NHTSA campaign 25V080 / Audi 93AA covers certain 2022 A7 E plug-in hybrid vehicles whose high-voltage battery may overheat, increasing fire risk. This current campaign expands and replaces NHTSA 24V898. Audi uses diagnostic software and available online vehicle data to identify batteries requiring further action. Eligibility and instructions are VIN-specific.

How to Fix

Check the VIN and current campaign instructions with Audi or NHTSA immediately. Dealers install advanced diagnostic software free of charge, monitor available vehicle data and replace affected battery modules or batteries as directed. Follow any Audi instruction not to charge the vehicle until the remedy is complete; vehicles without online data are advised by the campaign not to charge until the final remedy is available. Do not substitute a 12-volt battery, charger or portable EVSE.

Audi service action 27BQ covers certain 2019-2020 A7 vehicles in the United States and Canada. A defective starter-alternator may prevent the start/stop system from working and can increase emissions. This is a VIN-specific service action; it does not establish the former broad MMI, 12-volt battery or 2019-2025 electrical-failure narrative.

Common Symptoms

  • Start/stop system does not operate
  • Starter-alternator fault identified by Audi

How to Fix

Ask an authorized Audi dealer to check the VIN in Elsa for an open 27BQ action. Eligible vehicles receive a replacement starter-alternator at no charge under the action. Diagnose any current no-start, warning-light or infotainment concern separately; do not buy a battery, maintainer or scan tool from this summary.

NHTSA campaign 21V159000 covers a passenger front airbag whose cover score line — the engineered tear seam that lets the airbag open through the dashboard — may not have been manufactured correctly. In a crash the airbag can deploy improperly and eject plastic debris into the cabin, injuring the occupant it is meant to protect. Affected vehicles include 2019-2021 A6 sedan and A7, 2020-2021 A6 Allroad, S6 and S7, and 2021 RS6 Avant and RS7, with model-specific production windows. The A7 window is August 7, 2018 through December 9, 2020. Dealer and owner notification was planned for May 7, 2021.

Common Symptoms

  • No driver-detectable symptom - defect is only identifiable by VIN and inspection
  • Airbag warning light in unrelated cases should still be diagnosed

How to Fix

Free recall remedy: the dealer inspects the passenger airbag score line in the instrument panel and, if necessary, reworks it to specification at no charge (no replacement part is used). There is no owner-visible symptom and no warning light for this defect, so check open recalls by VIN and ask an Audi dealer to confirm campaign inclusion and repair history; absence from an open-recall search does not establish that the vehicle was never affected. This is worth checking on any used C8 A7 whose recall history is unclear.

On certain 2021 Audi A7 vehicles, a software fault can prevent the rearview image from appearing when reverse is selected, sometimes leaving the infotainment main unit inoperative. Recall 22V742 / 91DZ addresses this rear-visibility noncompliance; a missing image increases reversing collision risk. VIN eligibility must be checked rather than inferred from model year alone.

Common Symptoms

  • Black or blank screen when reverse is selected
  • Rearview camera image never appears
  • MMI main unit unresponsive or dark

How to Fix

Contact an authorized Audi dealer without delay to check campaign eligibility and arrange the free 91DZ infotainment software update. Audi estimated about two hours for the work, with extra workshop time possible. A later, separate campaign, 25V900 / 90TV, includes certain 2019–2025 A7s; ask the dealer to check both campaign histories and diagnose any continuing loss of camera image. Use extra caution when reversing if the image is unavailable.

Certain 2012–2013 Audi A7 vehicles are covered by recall 16V646 / 24BZ because the under-hood fuel hose may deteriorate and leak. Fuel near an ignition source creates a fire risk. A separate campaign, 17V781 / 20AR, concerns a fuel-line compression point on certain 2012–2014 A7 vehicles. Ask Audi to check each VIN and campaign history independently; one completed repair does not establish that both actions are complete.

Common Symptoms

  • Fuel odor in the vehicle
  • Fuel leakage from the affected under-hood hose

How to Fix

For an eligible vehicle, an authorized Audi dealer replaces the in-tank fuel pump and under-hood fuel hose free of charge under recall 16V646 / 24BZ. Ask the dealer to verify VIN applicability and completion history for this campaign and the separate 17V781 / 20AR fuel-line recall. If fuel odor is noticed, immediately contact the nearest authorized Audi dealer for inspection advice; do not treat prior recall work as proof that a new fuel odor is harmless.

The A7 shares the C7 platform with the A6 and uses the same 3.0T supercharged V6. The supercharger nose cone front bearing degrades with age and mileage, producing an increasingly loud whine under boost. The bearing can eventually seize, causing internal supercharger damage and significant power loss.

This issue also affects: Audi A5, Audi Q7, Audi S5

Common Symptoms

  • Whining noise that increases with engine RPM
  • Louder whine under boost/hard acceleration
  • Supercharger sounds louder than usual
  • Slight loss of boost pressure
  • Fine metallic particles in supercharger oil
  • Noise absent at idle, present with throttle input

How to Fix

Replace the nose cone bearing assembly. Aftermarket upgraded bearings from 034 Motorsport or JHM are recommended over OEM. The repair can be performed without removing the supercharger. Change supercharger oil every 50,000 miles as preventive maintenance.

Typical repair cost:$500 - $2,500

All A7 models with direct-injection engines (2.0T, 3.0T supercharged) suffer from severe carbon buildup on intake valves. The 3.0T CREC engine in S7 and RS7 models is particularly susceptible and will likely fail after 60,000 miles if carbon is not removed. In direct-injection engines, fuel bypasses the intake valves, leaving them exposed only to oil vapors from the PCV system. These vapors bake onto valve backs as hard carbon deposits over 60,000-100,000 miles. Carbon restricts airflow, causing rough idle, misfires, hesitation, and power loss. In severe cases, carbon prevents valves from seating properly, causing compression loss and valve damage requiring engine replacement. AudiWorld reports the ONLY effective fix is walnut blasting every 60,000 miles. This is preventive maintenance, not a "if needed" repair.

This issue also affects: Audi A5, Audi Q5, Audi Q7

Common Symptoms

  • Rough or unstable idle (engine shakes)
  • Hesitation or stumbling on acceleration
  • Significant power loss (especially noticeable on S7/RS7)
  • Poor fuel economy (3-5 MPG drop)
  • Check engine light with misfire codes (P0300-P0306)
  • Engine runs rough when cold, smooths when warm
  • Hard starting or extended cranking

How to Fix

WALNUT BLASTING: Remove the intake manifold (supercharger on the 3.0T) and blast walnut shells through the intake ports to remove carbon ($800-$1,500 for A7; $1,200-$2,000 for S7/RS7 due to complexity). Requires specialized equipment - not DIY-friendly. Confirm heavy deposits by borescope before paying for cleaning; there is no manufacturer-set cleaning interval. PREVENTION (owner-community practice, not an Audi instruction): some owners fit an oil catch can to reduce PCV oil vapour reaching the valves, and keep oil changes on time; results vary, and a catch can may affect warranty or emissions compliance. Fuel or oil additives cannot reach the intake valves on a direct-injection engine and are not a remedy.

Audi TSB 2039995/2 applies to 2012-2015 A7 vehicles with the 3.0 TFSI engine when a rattle lasts about one to three seconds on the first start of the day. Audi attributes the supported sound to one or both upper timing-chain tensioners and states that this brief condition does not damage the engine. The bulletin does not support the former universal chain-jump, DTC or 2012-2018 failure narrative.

This issue also affects: Audi S4, Audi Q7

Common Symptoms

  • One-to-three-second rattle on the first start of the day

How to Fix

Have a technician reproduce and compare the exact first-start sound using Audi’s bulletin. If it matches, follow the VIN- and engine-specific repair procedure for both upper timing-chain tensioners. Diagnose a longer rattle, warning light, running fault or different noise separately; do not order a complete chain kit from this summary.

The 3.0T V6 thermostat housing in the C7 A7 develops coolant leaks from the plastic housing and its O-ring seals. The housing is located at the front of the engine and cracks or warps over thermal cycling. Coolant leaks onto the serpentine belt area and can cause belt slippage or overheating if coolant loss is significant.

This issue also affects: Audi A5, Audi Q7, Audi S5

Common Symptoms

  • Coolant puddle under front of vehicle
  • Sweet coolant smell from engine bay
  • Low coolant warning light
  • Coolant visible on serpentine belt
  • Temperature gauge reading higher than normal
  • Steam from engine bay
  • Coolant residue around thermostat housing area

How to Fix

Replace the thermostat housing assembly with an updated part. The O-ring seals should always be replaced. Some owners upgrade to aluminum aftermarket housings for improved durability. The water pump should be inspected during this repair as it shares the same coolant circuit.

The 2014-2016 A7 3.0 TDI was part of the Volkswagen Group 3.0-liter diesel emissions scandal. These cars contained undisclosed software that reduced NOx aftertreatment during normal driving, and they were covered by the Second Partial Consent Decree between Audi, the EPA, DOJ, CARB and the California Attorney General. EPA and CARB approved an emissions modification specifically for model year 2014-2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5 diesels. The settlement required a recall of affected generation-2 vehicles. For the older generation-1 Touareg and Q7 diesels, Volkswagen had to offer buyback or lease termination and, if approved, an emissions modification alternative. This matters to any used A7 TDI buyer: an unmodified car may not pass emissions inspection in some states and carries a documented compliance history that must be checked.

Common Symptoms

  • Emissions inspection failure on an unmodified car
  • Dealer notice of a mandatory emissions modification

How to Fix

Free remedy: an authorized Audi dealer performs the approved emissions modification (engine and emissions-control software, and hardware where specified) at no charge, and the settlement extended emissions-related warranty coverage on the modified components. Verify by VIN through Audi's diesel information portal whether the modification has already been applied — many used A7 TDIs changed hands mid-program.

The S7 with the 3.0T supercharged V6 (2012-2018) uses an electromagnetic clutch to engage the supercharger. Over time, the clutch disc wears out or the torsional isolator (damper) fails, creating a loud rattling, grinding, or "bag of marbles" sound from the front of the engine. This is most noticeable on cold starts or under load. A failed clutch prevents the supercharger from engaging, causing significant power loss. A failed isolator damages internal supercharger components, requiring complete supercharger replacement. Oil contamination accelerates wear—if oil becomes contaminated with dirt or debris, it causes premature failure of internal components. AudiWorld forums report failures between 60,000-120,000 miles, with repair costs of $1,500-$5,000.

This issue also affects: Audi A1, Audi A3, Audi A6

Common Symptoms

  • Loud rattling, grinding, or "marbles" noise from front of engine
  • Noise most noticeable on cold start or light throttle
  • Significant power loss (feels like naturally aspirated V6)
  • Check engine light with underboost codes (P0234, P0299)
  • Supercharger whine disappears (clutch not engaging)
  • Belt squeal from supercharger pulley
  • Metal debris in oil (severe internal damage)

How to Fix

If caught EARLY (noise but no power loss): Replace supercharger clutch ($1,500-$2,500 with labor). Clutch can be replaced without removing supercharger. If SEVERE (grinding + power loss): Replace complete supercharger assembly ($3,500-$5,000 installed). PREVENTION: Service supercharger oil every 40,000 miles despite Audi saying "lifetime." Change engine oil every 5,000 miles with high-quality synthetic. Avoid aggressive launches—gentle driving extends clutch life. Budget for this repair if buying a used S7.
