How Much It Costs to Replace the Engine Mount on an Audi A4

Replacing an engine mount on an Audi A4 typically costs between $350 and $900 per mount at a professional shop in the United States, depending on model year, engine type (gasoline vs. diesel, four‑cylinder vs. six‑cylinder), whether the mount is hydraulic or electronically controlled, and local labor rates. Parts usually run from about $120 to $450 each, with labor commonly adding $200 to $450 per mount.

What an Engine Mount Does — And Why It Matters on an Audi A4

The engine mount on an Audi A4 secures the engine to the chassis, isolates vibration, and keeps the drivetrain properly aligned under acceleration, braking, and cornering. When mounts wear out or fail, the car can develop harsh vibrations, clunks, and even drivetrain misalignment that, if left unchecked, may damage other components and reduce safety.

Because modern Audi A4s often use hydraulic or electronically controlled “active” mounts, replacement costs are higher than for simpler rubber mounts found on older or less complex vehicles.

Typical Cost Range for Audi A4 Engine Mount Replacement

The following sections break down the typical price ranges owners can expect, based on model generation and mount type, acknowledging that actual invoices will vary by region and workshop.

Overall Cost Range

From current repair data and shop estimates in 2024, these are the broad price ranges for replacing a single engine mount on an Audi A4 in North America:

The list below outlines approximate cost brackets that most Audi A4 owners will see for a single engine mount replacement, providing a quick financial snapshot before diving into details like parts, labor, and model variations.

• Typical total cost per mount: $350–$900
• Parts only (aftermarket standard mount): $120–$250
• Parts only (OEM / electronic or hydraulic mount): $250–$450+
• Labor (independent shop): $200–$350 per mount
• Labor (Audi dealer / premium shop): $250–$450 per mount

These figures give a workable planning range: a relatively simple mount on an older A4 may cost toward the low end, while newer models with active mounts and dealer labor can push costs toward or above the high end.

By Generation and Engine Type

Different A4 generations and engines use different mount designs, which affects pricing and labor time.

The following list breaks down cost tendencies by common Audi A4 generations and engine types, helping owners place their likely costs within a narrower band.

• B7 (2005–2008) – Simpler mounts on most trims:
  

  • Parts: ~$120–$220 per mount (standard or hydraulic)
  • Labor: ~$200–$320
  • Estimated total: $320–$540 per mount

• B8 (2009–2016) – More use of hydraulic and electronically controlled mounts:
  

  • Parts: ~$180–$350 (aftermarket to OEM)
  • Labor: ~$220–$380
  • Estimated total: $400–$730 per mount

• B9 (2017–present) – Complex mounts, especially on higher-output engines:
  

  • Parts: ~$250–$450+
  • Labor: ~$250–$450 (more involved procedures on some models)
  • Estimated total: $500–$900+ per mount

• Diesel and performance variants (e.g., S4) – Often use heavier-duty or active mounts:
  

  • Parts frequently at the upper end of the range
  • Labor can be higher if access is tighter or procedures are more complex

While exact numbers hinge on VIN-specific parts and local wages, this generational overview shows a clear trend: newer, more advanced A4s tend to carry higher mount and labor costs than earlier models.

Parts Costs: OEM vs. Aftermarket and Mount Types

The cost of the mount itself is the largest single variable, especially because Audi uses several different mount technologies in the A4 lineup.

Types of Engine Mounts Used on Audi A4

Different mount designs provide different levels of refinement and durability, which in turn affects price and repair complexity.

The following list explains the main mount types you may encounter on an Audi A4 and how they influence replacement cost.

• Conventional rubber mounts
  

  • Used mainly on older or base configurations.
  • Least expensive, simpler design.
  • Typical cost: ~$80–$150 (aftermarket), somewhat more for OEM.

• Hydraulic (fluid-filled) mounts
  

  • Common on later A4s to reduce vibration and harshness.
  • More refined feel but more expensive to replace.
  • Typical cost: ~$150–$300 (aftermarket/OEM mix).

• Electronically controlled / active mounts
  

  • Found on some newer or higher-output A4 engines.
  • Can change stiffness based on driving conditions.
  • Most expensive, sometimes require coding or adaptation after installation.
  • Typical cost: ~$250–$450+ per mount (often OEM only or limited aftermarket).

Knowing which type is fitted to your car is key to getting realistic estimates, as an electronically controlled mount can easily cost two or three times as much as a basic rubber one.

OEM vs. Aftermarket Pricing

Drivers also face a choice between original Audi parts and third‑party alternatives, each with cost and quality implications.

The list below outlines the typical trade-offs between OEM and aftermarket mounts for an Audi A4, giving a clearer picture of where savings are possible and where they may not be wise.

• OEM (Original Equipment Manufacturer)
  

  • Purchased from Audi dealers or OEM-branded suppliers.
  • Best assurance of correct fit and performance.
  • Often required or strongly recommended for electronically controlled mounts.
  • Cost: frequently 20–50% higher than aftermarket, sometimes more.

• Aftermarket (reputable brands)
  

  • Brands like Lemförder, Febi, Corteco and others often supply parts close to OEM quality.
  • Cost savings can be significant, especially for hydraulic mounts.
  • May ride slightly harsher or last somewhat less long, depending on brand.
  • Cost: typically $120–$250 for most A4 mounts.

• Budget / no-name mounts
  

  • Lowest price, but often shortest lifespan and worst vibration control.
  • Not recommended for a car with the refinement expectations of an Audi A4.

In practice, many independent European specialists use high-quality aftermarket mounts that balance cost and durability, while dealers almost always fit OEM, explaining some of the spread in estimates.

Labor Costs and Time: What You’re Paying For

Labor costs for engine mount replacement on an Audi A4 reflect both the hourly rate and the complexity of accessing and supporting the drivetrain during the job.

How Long the Job Takes

Engine mount replacement is rarely a quick “unbolt and swap” process on a modern A4, due to tight packaging and the need to support the engine safely.

The next list summarizes typical labor times and factors that can make the job quicker or longer on different Audi A4 configurations.

• Typical labor time per mount:
  

  • Approximately 1.5 to 3.0 hours per mount in most cases.
  • Left and right mounts often have similar labor times, but one side may require more disassembly.

• Influencing factors
  

  • Engine layout (2.0 TFSI vs. V6 vs. diesel).
  • Quattro vs. front-wheel drive (driveline packaging can affect access).
  • Whether subframe components or brackets must be loosened or lowered.
  • Presence of rust or seized fasteners on older cars.
  • Need for electronic coding or initialization on active mounts.

• Labor rate
  

  • Independent European specialist: commonly $110–$170 per hour.
  • Audi dealership in major cities: commonly $170–$250+ per hour.

These factors combine to explain why two shops may quote very different totals for seemingly the same job, even when using similar parts.

When You Might Need More Than One Mount Replaced

A failing engine mount rarely fails in isolation; by the time symptoms appear, other mounts may be worn and related parts can be stressed.

Multiple Mounts and Additional Components

Owners are often quoted for more than a single mount, which can significantly alter the total bill.

The list below describes typical add-ons to a basic engine mount job and how they influence cost.

• Replacing both main engine mounts
  

  • Commonly recommended if one side has clearly failed and the other is heavily worn.
  • Labor overlap can reduce time: replacing both might be 2.5–4.5 hours instead of simply doubling the single-mount time.
  • Expected total: often in the $700–$1,500 range for both mounts, depending on parts choice and shop.

• Transmission mount (or “rear” mount)
  

  • Sometimes replaced at the same time, especially on higher-mileage A4s.
  • Parts are often cheaper than engine mounts, but labor can add 1–2 hours.
  • Total adds roughly another $200–$500 to the bill, depending on design.

• Related hardware and consumables
  

  • New stretch bolts, brackets, or bushings if specified by Audi’s repair procedures.
  • Occasional need for alignment if subframe is loosened or lowered.
  • Potential added cost: typically $50–$200.

Accepting a quote for multiple mounts can feel costly up front, but often prevents having to repeat similar labor later when the remaining worn mount inevitably fails.

How to Get a Realistic Estimate for Your Specific Audi A4

Because individual A4s vary widely by year, engine, drivetrain, and installed options, the surest way to nail down cost is with VIN-specific quotes.

Steps to Narrow Down Your Price

With a few preparation steps, owners can quickly obtain accurate quotes and avoid surprises when the car is already on a lift.

The list below outlines practical actions to get solid, comparable estimates tailored to your specific Audi A4.

• Gather key information
  

  • VIN (Vehicle Identification Number).
  • Model year, trim level, engine type (e.g., 2.0 TFSI, 3.0 TDI).
  • Approximate mileage and whether the car is Quattro or front-wheel drive.

• Call at least two or three shops
  

  • One Audi dealer for a benchmark OEM quote.
  • One or two independent European specialist shops.
  • Ask them to price both OEM and high-quality aftermarket where appropriate.

• Ask for a line-item estimate
  

  • Separate parts and labor.
  • Note the estimated labor hours and hourly rate.
  • Ask if new hardware or alignment might be required.

• Clarify diagnostic and follow-up charges
  

  • Any fee for confirming the mount is faulty (some shops apply this to the repair).
  • Additional cost if other mounts or related parts are found to be worn.

Completing these steps usually yields a spread of realistic quotes, from which you can choose based on cost, reputation, and whether OEM parts are important for your situation.

Can You Drive With a Bad Engine Mount — and Is DIY Worth It?

Many owners confront the issue only after noticing shaking or clunking, then wonder how urgent the repair really is and whether they can save money by doing it themselves.

Risks of Delaying Replacement

A failing mount does not usually strand the car immediately, but delaying repair carries real downsides.

The list below outlines what can happen if you continue driving your Audi A4 with a worn or broken engine mount.

• Increased vibration and noise
  

  • Noticeable shaking at idle and when shifting between drive and reverse.
  • Reduced comfort, particularly on longer drives.

• Drivetrain stress
  

  • Extra movement can strain CV joints, exhaust components, hoses, and wiring.
  • Premature wear in related mounts or bushings.

• Safety and control issues
  

  • In severe cases, engine movement during acceleration or braking can be abrupt.
  • Potential interference with other components if a mount fails completely.

• Higher eventual repair bills
  

  • Damage caused by excessive movement may add to the final cost.
  • Waiting until multiple mounts fail can mean more extensive labor and parts.

While a slightly worn mount might not be an emergency, once symptoms become obvious—especially clunks or visible engine movement—prompt replacement is usually the cheaper and safer option in the long run.

DIY vs. Professional Replacement

Some mechanically inclined owners consider replacing engine mounts themselves to save hundreds of dollars, but on an Audi A4 this is not a simple beginner job.

The following list highlights factors DIY enthusiasts should weigh before attempting engine mount replacement on an A4.

• Tools and equipment required
  

  • Safe way to support the car (stands or lift).
  • Engine support bar or suitable jack with appropriate blocks.
  • Torque wrench and often specialty sockets or extensions.

• Technical difficulty
  

  • Limited space in the engine bay, especially on later generations.
  • Correctly supporting the engine is critical to avoid damage.
  • Some active mounts may require diagnostic tools for coding or adaptation.

• Cost savings
  

  • Labor savings can be substantial: potentially $200–$450 per mount.
  • Mistakes, however, can be expensive if they damage surrounding components.

• Warranty and resale considerations
  

  • Dealer service with OEM parts may help preserve warranty coverage and service history.
  • DIY work is harder to document for future buyers.

For most owners, especially with newer A4s or active mounts, professional replacement is generally the safer and more predictable route, even if it costs more up front.

Summary

For an Audi A4, replacing a single engine mount typically costs between $350 and $900, with parts running about $120–$450+ and labor adding $200–$450 depending on shop type, regional labor rates, and vehicle configuration. Older A4s with simpler mounts sit toward the lower end of that range, while newer B8 and B9 models equipped with hydraulic or electronically controlled mounts, serviced at a dealer, tend toward the upper end.

Owners can refine that estimate by identifying their exact model, engine, and mount type, then seeking line-item quotes from both a dealer and at least one independent European specialist. While driving for a short period with a mildly worn mount is sometimes possible, significant vibration, clunking, or visible engine movement are signs that prompt replacement is wise—both for comfort and to prevent collateral damage that can make an already expensive repair even costlier.

How do I know if my Audi engine mount is bad?

One of the most common engine mount symptoms is increased vibrations while using your vehicle. If you start your engine and notice that it is making more noise than usual and you can feel more vibrations than usual, this is a key sign of a worn engine mount that may need replacing.

Is it worth fixing engine mounts?

No you can’t repair a motor mount, it needs to be replaced. If you don’t replace the motor mount, your engine is not being held stable and it can cause other problems from the vibration and movement of the engine.
