What is an Audi Suspension?

What is a Suspension?

A vehicle's suspension is a complex system of components designed to support the car's weight, absorb impacts from the road, and ensure a comfortable and stable ride for the passengers. It is an intermediary between the road and the vehicle, softening the blows from potholes, bumps, and other road imperfections.

At its core, a suspension system comprises springs, shock absorbers (or struts), and linkages that connect a vehicle to its wheels. The springs support the car's weight and absorb large bumps, while the shock absorbers or struts dampen vibrations and smaller jolts, preventing the car from excessively bouncing an impact. The linkages, including ball joints, control arms, and bushings, provide structural support and maintain wheel alignment.

In essence, a well-functioning suspension system is crucial for passenger comfort and vehicle safety. It ensures stability, maintains contact between the tires and the road, and ultimately plays a pivotal role in the handling and braking capabilities of the vehicle.

What is an Audi Suspension?

An Audi suspension is a culmination of advanced engineering, innovation, and a deep understanding of driving dynamics. While it retains the primary function of any suspension system - supporting the vehicle's weight and absorbing road impacts - Audi's suspension is distinctive in its commitment to delivering sporty handling and luxury comfort, a combination not easily achieved.

One hallmark of Audi's suspension is its adaptability. Many Audi models are equipped with the brand's Adaptive Air Suspension, which automatically adjusts the firmness and damping characteristics based on the road conditions and driving style. This results in an optimised balance between comfort and performance. With the push of a button, drivers can transition from a plush, relaxed ride to a firmer, sportier setup.

What Areas Are Tested With An Audi Suspension?

  1. Shock Absorbers and Struts: These components are critical for dampening the vibrations and jolt from road imperfections. Technicians will typically check for signs of leaking fluid, worn-out mounts, and any unusual noises. A dysfunctional shock absorber or strut can reduce ride comfort and compromise handling.

  2. Springs: Springs bear the vehicle's weight and are responsible for maintaining its height. They also absorb larger bumps and impacts. When checking springs, technicians look for signs of sagging, cracks, or breaks, ensuring they are not worn out and provide the right amount of tension.

  3. Linkages encompass various parts like tie rods, ball joints, and control arms. These components ensure that the wheels move in tandem with the car's suspension. During a test, signs of excessive wear, corrosion, or damage to these linkages are identified.

  4. Bushings: Made of rubber or polyurethane, bushings act as cushions in the suspension system, minimising vibrations. They are checked for signs of cracking, hardening, or any deformities that might reduce their efficacy.

  5. Wheel Alignment: A misaligned wheel can lead to uneven tire wear, compromised handling, and decreased fuel efficiency. Technicians use specialised equipment to measure the wheel angles, ensuring they follow Audi's recommendations.

  6. Adaptive Systems: Some high-end Audi models are equipped with adaptive suspension systems. These automatically adjust based on driving conditions and driver preferences. This system's functionality, sensors, and electronic components are rigorously tested for accurate responses.

  7. Suspension Noise: Any unusual noises when driving over bumps or during turns can indicate issues. Technicians will often perform road tests to listen for clunks, rattles, or squeaks, which can pinpoint underlying problems.

  8. Tire Condition: While not a direct part of the suspension, tires play a pivotal role in suspension performance. Worn-out or unevenly worn tires can strain the suspension system. Technicians often inspect the tires for wear patterns, as they can indicate issues like misalignment or problems with the shocks or struts.

Why Is An Audi Suspension Test Important?

Audi vehicles, renowned for their blend of performance, luxury, and cutting-edge technology, rely heavily on their sophisticated suspension systems to deliver a driving experience that aligns with the brand's reputation. Ensuring that this intricate system is functioning optimally is where the significance of an Audi suspension test comes into play.

  1. Safety: At the forefront of any vehicle maintenance is the safety of its passengers. A compromised suspension can reduce vehicle stability, especially during sudden maneuvers, making it potentially hazardous. By routinely testing the suspension, potential issues can be detected and rectified early, ensuring the vehicle's safe operation.

  2. Ride Quality: Audi is synonymous with a smooth, plush ride. A malfunctioning suspension system can lead to a rough, jarring ride, diminishing the driving pleasure. Regular tests ensure that the distinctive Audi ride quality is maintained.

  3. Vehicle Longevity: A compromised suspension system can cause undue stress on other vehicle components, such as the chassis or tires. By ensuring the suspension is in top shape, the longevity of the entire vehicle can be enhanced.

  4. Tire Wear: An ill-maintained suspension system can lead to uneven or accelerated tire wear. Regular suspension checks can prevent this, ensuring uniform tire wear and extending their lifespan.

  5. Fuel Efficiency: A misaligned suspension can increase rolling resistance, causing the engine to work harder and consume more fuel. Regular tests can keep the vehicle's alignment in check, optimising fuel efficiency.

  6. Performance: Audi's are celebrated for their sharp handling and spirited driving dynamics. A perfectly tuned suspension is key to this. Any issues or discrepancies in the system can impact the car's handling and cornering abilities.

  7. Cost Savings: Major repairs and replacements can be circumvented by routinely testing and addressing minor suspension issues. This saves money in the long run and prevents potential breakdowns or malfunctions.

How Often to Have an Audi Suspension Changed?

The suspension system is the backbone of a vehicle's driving experience, especially for a luxury brand like Audi. Keeping the suspension in optimal condition ensures the vehicle remains safe and comfortable and delivers peak performance. However, unlike routine oil changes or tire rotations, there isn't a universally set interval for changing the entire suspension. Here's a closer look at understanding the nuances of this process.

  1. Typical Lifespan: Suspension components vary in their lifespan. While shocks and struts typically last between 50,000 and 100,000 miles, other components might require attention sooner or later based on driving conditions. It's essential to be guided by your vehicle's manual or consult an expert for your particular model.

  2. Driving Conditions: Vehicles frequently driven on rough or unpaved roads or areas with significant potholes and speed bumps may experience faster wear on their suspension components. In such conditions, more frequent inspections and potential replacements are advised.

  3. Performance Issues: If your Audi begins to exhibit symptoms like excessive bouncing, nose dives when stopping, or drifting during turns, these could be indicators that certain suspension components need replacement.

  4. Regular Inspections: Instead of a predetermined interval for changing the entire suspension, regular inspections are more practical. During routine service visits, having the mechanic check the suspension can help identify worn-out parts before they pose a bigger problem.

  5. Visual Checks: Sometimes, a simple visual check can highlight issues. Sagging corners, leaking fluids around the shocks or struts, or damaged bushings can be telltale signs.

  6. Noise: Unusual sounds like clunking, rattling, or squeaking when driving over bumps or during turns can indicate potential suspension issues that warrant a closer look.

  7. Tire Wear: Uneven tire wear can sometimes be attributed to a misaligned or worn-out suspension. Regularly checking your tires for uneven patterns can act as an indirect indicator of suspension health.

  8. Safety Considerations: Remember, a faulty suspension doesn't just affect comfort; it impacts the vehicle's handling and stability. Any doubts regarding the suspension should be promptly addressed to ensure safety.

When to Have an Audi Suspension Changed?

Audi's suspension system, a blend of innovation and engineering precision, is pivotal in ensuring the vehicle's performance, safety, and comfort. While routine maintenance is crucial, specific signs and circumstances suggest that it might be time to consider changing parts or even the entirety of the suspension system.

  1. Noticeable Ride Deterioration: One of the most distinct indicators is a noticeable drop in ride quality. If your Audi starts feeling bumpier, less controlled, or more floaty than usual, it's a clear sign that your suspension components might be wearing out.

  2. Excessive Bouncing: If your car bounces multiple times after going over a speed bump or a pothole, it suggests that the shock absorbers or struts might be failing and need replacement.

  3. Vehicle Sagging: If one corner of your Audi is sitting lower than the others when parked on a level surface, it could indicate a damaged spring or other suspension component that requires replacement.

  4. Drifting or Pulling: If you notice your Audi drifting to one side during turns or pulling to one side while driving straight, it may be due to worn-out suspension parts affecting vehicle stability.

  5. Unusual Noises: Sounds like clunks, squeaks, or rattles when driving over uneven surfaces can signal that parts of the suspension system are loose or damaged.

  6. Uneven Tire Wear: If your Audi tires are worn out unevenly, especially in patches or on one side, it can result from alignment issues stemming from a deteriorated suspension.

  7. Visible Damage: During routine checks or maintenance, if you or your mechanic notice visible damage like fluid leaks from the shock absorbers, cracked bushings, or corroded components, it's a telltale sign that replacements are in order.

  8. Steering Issues: Difficulty in steering, especially at low speeds or a feeling of the car being unresponsive, can often be traced back to suspension problems.

What Can't an Audi Suspension Test For?

While an Audi suspension test is crucial for assessing the health and performance of the suspension system, there are certain aspects it cannot directly detect. These limitations necessitate a broader approach to vehicle maintenance and inspection.

  1. Internal Damages: A standard suspension test primarily examines external components. Without disassembly, it cannot detect internal damages within shock absorbers, struts, or springs.

  2. Alignment Issues: While a suspension test can highlight potential problems with suspension components, it can't directly diagnose alignment issues, which require a separate wheel alignment procedure.

  3. Steering Components: Steering-related problems might only sometimes be traced back solely to the suspension. A dedicated steering system check might be necessary.

  4. Brake Issues: Although closely related, suspension tests don't inherently identify issues in the braking system, such as brake pad wear, calliper malfunctions, or brake fluid leaks.

  5. Electrical and Sensors: Modern suspensions might have adaptive components, but suspension tests can't directly diagnose electrical or sensor-related problems in these systems.

  6. Transmission or Engine Problems: Vibration issues caused by problems in the transmission or engine might manifest similarly to suspension problems. However, these require separate diagnostics.

  7. Damage to Non-Suspension Components: If impact or collision damages extend to non-suspension parts of the vehicle, a suspension test won't directly identify these issues.

  8. Worn Tires: While related to suspension health, tire wear can also be influenced by factors like improper alignment, inflation, or driving habits. A dedicated tire inspection might be needed.

Can I Perform an Audi Suspension Change at Home?

Changing the suspension of an Audi at home is a significant mechanical undertaking that demands a high level of expertise, specialised tools, and a meticulous approach. While it's technically possible for experienced DIY mechanics, it's crucial to understand the complexities involved and consider the potential risks.

  1. Specialised Tools: Changing a suspension system requires various specialised tools, including spring compressors, torque wrenches, ball joint separators, and more. These tools might only be readily available to some home mechanics.

  2. Expertise: A suspension system involves intricate components and precise adjustments. A deep understanding of mechanics, alignment, and suspension geometry is necessary to ensure a safe and effective installation.

  3. Safety Risks: Changing suspension components involves working with heavy parts, springs under tension, and the vehicle lifted off the ground. One wrong move can lead to serious injuries.

  4. Alignment: Altering suspension components can affect the vehicle's alignment. This requires specialised equipment and expertise to ensure the wheels are properly aligned, maintaining safe driving conditions.

  5. OEM Compatibility: Audi's suspension components are engineered to work harmoniously with the vehicle's design. Choosing aftermarket parts with compatibility can lead to better performance and safety risks.

  6. Electronic Systems: Many modern vehicles, including Audis, have electronic systems that interact with the suspension. Changing components might necessitate reprogramming or calibration.

  7. Warranty Considerations: If your Audi is under warranty, modifying the suspension might void the warranty if not performed by authorised technicians.

  8. Time and Patience: Changing a suspension is time-consuming and demands patience. Rushing through the process can lead to mistakes.

  9. Professional Inspection: A trained technician can identify other potential issues during a suspension change, preventing future problems.

B8/B8.5 Buyer's Guide and "Looking to buy" Question Thread

Long overdue, but I think that it's way past time that we compiled purchase advice into one single thread which hopefully we can get stickied. If anyone has additional specifics to add, post it below and I'll work to integrate as much as possible into this initial post. Anyone with questions about a purchase they are considering can feel free to post here for advice and feedback.

For anyone looking to buy a used or CPO B8 ( through ) or a B8.5 (-), they're great cars and generally very reliable. This thread will hopefully answer some common questions about the cars, and provide some specific things to consider and watch out for when purchasing. If you are looking at an older or higher-mileage car, please see the bottom of this post for maintenance to be aware of.

- was the first year the B8 platform was sold in the US. It was also the only year that the 3.2 V6 was available. Most 2.0T motors from this year, a decent percentage of '10s, and some '11MY cars were affected by severe oil consumption, requiring a PCV replacement (stage 1) and usually a full engine rebuild for new pistons and rings (stage 2). These repairs were almost exclusively done by Audi dealerships. If you call a dealership with the VIN of the car(s) you're looking at, they'll be able to tell you if stages 1 and/or 2 of the consumption fix were completed. If stages 1 and 2 completed, you're in the clear. If they weren't, or if only stage 1 was done, run; you don't want to pay for that $4-6k repair out of pocket. On a car with an unmodified motor, Audi extended the warranty for this car to 80,000 miles. Some people have had the repairs covered with modified cars, and some have also been covered until slightly over 100,000 miles. YMMV on both of these. The other early-build issues were intake manifolds cracking, control arms which caused a vibration at high speed, usually above 65 MPH and a power steering hose that would cause the wheel to shudder during slow-speed parking lot maneuvers. These were covered by Audi under service bulletins. If a seller has proof that they were resolved or Audi confirms that the repairs were done, you'll probably be fine. A lot of and a small percentage of cars also have a manufacturing defect which causes the turbo to fail prematurely. The wastegate was made of an insufficiently strong metal, causing it to bend over time and bleed boost. It isn't serviceable and requires a turbo replacement. A dealer should be able to confirm whether a given car was affected and whether or not the turbo was replaced.

- cars have significantly fewer issues than s. A much smaller percentage were affected by the intake manifold, oil consumption and turbo issues, and the control arms and steering shudder were resolved.

- cars were yet better; the oil consumption issue was almost completely resolved by mid-year production and the issues with the faulty turbo are no longer present. also marked the switch to the 8-speed automatic transmission (8AT) from the 6-speed (6AT) auto used in and 10 models. and '12 Premium trim level cars no longer have heated seats as standard equipment. Prem+ and Prestige do still include them.

- cars had no significant issues, however a very small percentage still suffered from high oil consumption.

- was the switch to the B8.5, which is mostly just a facelift. The Avant was also discontinued in the US and replaced with the Allroad, which has a higher ride height and additional body cladding. The engines and transmissions carried over, although some automatics with Quattro can run E85. The major mechanical change was the switch to electric power steering from the B8's hydraulic system. There is a noticeable difference in feel, and if you're debating between a and definitely drive both. Some early Allroads had defective electric steering racks. Audi replaced them under warranty.

- through cars didn't change much aside from slight variations in equipment, and a slight power bump. had larger shift paddles on the S-line steering wheel with the automatic transmission, and also included the S-line exterior (see below) and push button start as standard equipment with the Premium Plus trim level.

General minor issues that exist regardless of model year are wheel bearings, coil packs (updated versions of the coil pack largely eliminated this one), PCVs, and door lock solenoids as they age. The CVT transmission is also not known for smooth operation or longevity. Timing chain tensioners should be replaced around 100,000 miles as a preventative maintenance item. Any time the engine is apart, or around the same 100k mark, a carbon clean out can't hurt.

I won't even try to go through all of the variations of equipment and trim level, but I'll run through the basics.

Trim Levels:
- Premium
- Premium Plus
- Prestige

Engine/Transmission Possibilities:
- FWD/CVT (all years)
- 3.2 V6/6AT ( only)
- 2.0T/6MT (all years)
- 2.0T/6AT (-)
- 2.0T/8AT (-)

Premium model cars come with halogen headlights unless the lighting package is specified, and some do not have seat heaters. HID/LED headlights can be easily retrofitted into B8s for about $1,000, however B8.5s are more difficult to retrofit. Premium trim B8s have halogen tail lights, while some higher trims/packages (which vary by model year) also came with LED tail lights. These are difficult to retrofit into non-LED cars. B8.5 Premium trim package cars come standard with halogen headlights and tail lights, however higher trim levels (and Premium trim cars with the lighting package) come with HID/LED headlights and full LED tail lights.

For the high-end features and amenities that Audi is known for, Prem+ and Prestige cars are the way to go. Prem+ adds tri-zone climate control, automatic headlights and wipers, bixenon HIDs with LED DRLs, more display options in the gauge screen, and other minor features. It is highly recommended to get a car with Quattro; the FWD/CVT cars are not as high-performance or reliable as the Quattro models with the manual or automatic. If you're looking at pictures and it isn't specified, MMI controls behind the shifter (towards the rear of the car) means it is equipped with navigation. If not, the area behind the shifter will be blank and there will be a knob just below the MMI screen for audio control, and one knob (for Premium trim cars) or two knobs for climate control will exist on the console below that regardless. I annotated some pictures below to illustrate this.

Get a manual assuming that it would work for your use case. It transforms the character of the car completely, and makes it feel much more like a sports sedan. They retail for higher prices but hold value better. 5% or less of B8/B8.5 sedans are manual, and all Avants and Allroads were automatic.

The sports package (slightly lower sports suspension, 18 or 19 inch wheels, amazing sports seats, 3-spoke steering wheel, and S4 sway bars so there's a little less flex) is also very desirable, as is the S-line package. The contents of the S-line package varies slightly by year, but it has everything the sports package has, plus S4 front and rear bumpers, side blades, and even better seats. The Titanium/Black Optics package (the name changed midway through the B8's life) was available on standard and S-line cars and contains a gloss black grille surround along black window trim. The S-line Competition Plus package was available for and , and contained everything in the S-line package plus more aggressive front and rear bumpers and the black optics package.

A note on cars with S-line bumpers: for most of the B8.5's model run Audi offered an "S-line appearance package," which gives you the S-line front and rear bumpers along with side blades and (for some reason) S-line fender badges. The interior and suspension were left unchanged. This does NOT make the car an S-line, as all "true S-line cars" have the exterior equipment, interior changes, and sports suspension.

If you are looking at an older or higher-mileage B8, please see the list below. Thank you to member Zach L for aggregating all of this together.

- Timing Chain Tensioner: The original Audi design is faulty. Replace around the 100,000 mile mark (immediately if you just bought a car over this mileage without any record of the repair). Severe engine damage will result if the original part fully fails.
- Fuel Filter: Replace every 80,000 miles.
- Transmission fluid and rear differential fluid: All transmissions, even manual, and even though Audi says they use "lifetime" fluid. Fluid change should be done every 60-80,000 miles.
- Lube sunroof tracks: Seems unimportant until your sunroof fails. The OEM sunroof grease is proprietary. White lithium grease is an alternative, but not as good. Do this at 80-100,000 miles.
- Brake fluid and coolant flush: These should be done every 2 years regardless of mileage, especially the brake fluid.
- Intake valves carbon cleaning: Ideally every 40,000 miles, but most do every 80-100,000 miles. Helps fuel mileage, engine smoothness, and power. If the car has been burning oil and repaired, this becomes a higher priority as burnt oil will create carbon buildup.
- Timing Chain and Guide Rails: Replace every 120k miles to be safe. The guide rails are made of plastic and ruts wear into them from metal chain sliding across. See pictures below.

For more specific date on the oil consumption issue, here is a chart illustrating the percentage affected by high oil consumption by model year. For MY cars it was damn near 100%, so just assume it will need to be done if it isn't documented. Thanks to @audrobotic for tracking this down.
