Kestrel Take

Forty-one complaints is a thin public record, and thin means few people filed — it is not a reliability rating. What is in there is worth your attention: two of the four recalls are fire-risk campaigns on the 2.0T coolant pump, one is a fuel line that can weaken and leak, and the steering cluster is owners losing power assist with a 'do not drive' message and a four-figure quote. This is a $12,000 car with $5,000 repair bills in it, so the decision is not about the car, it is about the paperwork: pull the VIN on NHTSA, confirm all four campaigns are closed, and budget for German maintenance before you buy rather than after.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 41 owner complaints for the 2014 Audi A6, and 4 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. The largest single group is the fuel system at 20%. That is notable without being overwhelming — worth checking, not worth panicking about.

4 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2014 Audi A6

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Fuel line can weaken at a compression point and leak — recall, and owners still smell gasHigh — wallet impact

Recall 17V781 covers 2012–2014 A6 and A7: a compression point in the fuel line can weaken and leak, which near an ignition source is a fire. Dealers replace the line free. Owners here describe exactly that — a fuel smell in the cabin and trunk that gets stronger under acceleration, a puddle under the car near the exhaust, and in two cases the car losing power and stalling in traffic. If you smell fuel on the test drive, stop and check the campaign status before anything else.

Repair cost: $0 with the recall — verify it was performed; $400–$1,100 for a fuel line replaced outside it

Electromechanical power steering can quit with a 'steering malfunction — do not drive' warningHigh — wallet impact

A fifth of this record is the electric steering rack failing, usually at startup or without warning while moving: the assist disappears, the dash tells you not to drive it, and the wheel goes heavy enough that owners describe fighting the car home. One owner was quoted $5,100 by an Audi dealer for the rack. Another reports Audi mailed a limited extended-coverage letter in 2021 for the steering unit on certain 2011–2016 models — ask an Audi dealer whether this specific VIN carries that coverage, because it is per-VIN and it may have expired. On the test drive, turn the wheel lock to lock while parked and listen for whining or notchiness.

Repair cost (estimate): $1,900–$5,200 — about 42% of what this car is typically worth

Passenger seat occupant sensor mat fails, so the passenger airbag may not fire (recall)High — wallet impact

Recall 18V370 covers the A6 sedan back to 2012: the body-sensing mat in the front passenger seat wears, the Passenger Occupant Detection System misreads the seat, and the passenger airbag may not deploy properly in a crash. The dealer installs a PODS repair kit free. Most of this cluster is owners chasing that recall — parts were back-ordered for months in 2018 and 2019 — and one owner whose car fell outside the VIN range was quoted $1,172 for the module. Sit in the passenger seat and watch the 'passenger airbag off' light behave as someone sits down.

Repair cost: $0 with the recall — verify it was performed; $900–$1,400 for the module outside it

2.0T electric coolant pump can block or short and start a fire — two separate recallsHigh — wallet impact

Two campaigns, 17V002 and 18V229, both cover 2012–2015 A6 cars with the 2.0L turbo: the auxiliary electric coolant pump can clog with cooling-system debris or short internally, overheat and catch fire. The first campaign was a software fix that cuts power to a blocked pump; the second replaces the pump outright. A car that only ever got the software update is not the same as a car that got the new pump, so ask which was done and check both campaign numbers on the VIN lookup.

Repair cost: $0 with the recall — verify it was performed; $350–$750 for the pump if paid for

2.0T oil consumption — the level drops between services and the warning comes on earlyMedium

One owner here bought the car with 99,141 miles and had the low-oil warning within 103 miles of driving. Audi's 2.0T family has a long history of piston ring oil consumption, and on a car this age nobody is fixing it under warranty. Check the oil on the electronic gauge before the test drive and again after, ask the seller how much oil the car uses between changes, and treat 'a quart every 1,000 miles' as a price negotiation, not a quirk. A ring and piston job is engine-out money.

Repair cost (estimate): $0–$400 for a consumption test; $4,000–$7,000 for pistons and rings — around 57% of what this car is typically worth

Walk-Away Red Flags

✗Any fuel smell inside the cabin or from the trunk, worse in warm weather
✗A 'steering malfunction' or 'do not drive' message on the dash, even once
✗Airbag warning light lit, or the passenger-airbag-off light ignoring an occupant
✗Oil level below the minimum mark on a car the seller says was just serviced
✗Seller who cannot name which of the four recalls have been closed

Good Signs

✓All four campaigns shown closed on the NHTSA VIN lookup
✓An invoice for the replaced electric coolant pump, not just the software update
✓A steering rack replaced under Audi's extended coverage, with the paperwork
✓Oil consumption documented at less than a quart between 10,000-mile services
✓Service records from an Audi specialist with carbon cleaning listed
