Unconfirmed issues

Reported

Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.

S-tronic gearbox judder and mechatronic wear

Emerging

Owners report harsh, slamming gearchanges when re-accelerating, often starting around third gear, and full mechatronic unit failures needing a new ECU, mechatronics pack and clutch pack. It has turned up anywhere from well under 50k miles to past it, and one failure was tied to a dealer never renewing the S-tronic fluid on schedule. Repairs range from around £1,000 for a fluid change and adaptation reset up to £10,000 for a full unit replacement. No TSB or recall found for it.

V6 diesel engine cracks and coolant-in-oil

Emerging

A handful of 3.0 BiTDI owners report coolant turning up mixed into the sump oil, traced to hairline cracks in the block or head, showing up from around 47k miles. The fix is a new engine, quoted anywhere from £6,000 to £22,400, sometimes rising past £15,000 for a full replacement. Audi hasn't confirmed it as a design fault and it doesn't hit every car, but it's turned up on more than one separate 3.0 BiTDI, so it's worth flagging on an out-of-warranty V6 diesel.

V6 TDI emissions recall (NOx defeat device)

Confirmed pattern

The 3.0 V6 TDI diesel A7 was caught up in the VW Group emissions scandal: around 127,000 UK cars were recalled in January 2018 over what was described as an unacceptable shut-off device, with a further 60,000 recalled in May 2018 after excessive NOx was measured in normal driving, deliveries of the V6 diesel paused while it was sorted. The fix is a free software update at a dealer. It only touches the 3.0 V6 TDI, not the petrol or four-cylinder diesel A7s, so check the recall was actually carried out rather than just logged as due.

Suspension knocks and a harsh ride, worse on S line and big wheels

Partly in the MOT data

Reviews and owners both flag the ride as the A7's weak point rather than the smooth cruiser you'd expect: Honest John's own review notes S line cars on their lowered sports suspension feel noticeably stiffer, and Parkers lists a fidgety ride on standard suspension as one of the model's downsides. Separately, owners report suspension damage after impacts, one case running to £5,000 in wheel and suspension repairs after a steering fault. The measured MOT data for this shape backs suspension as the standout weak point, though it doesn't say whether it's springs, dampers, bushes or the optional air suspension actually wearing, so a knock or clunk on the test drive counts for more than any guess at which part.

Steering rack and EPS faults

Emerging

A small number of owners report electric power steering trouble, from a steering rack needing replacement around 50k miles for about £2,600, to a car where the steering froze twice with no fault found by the dealer. It isn't a high volume of reports, but a steering fault is safety-relevant and the repair isn't cheap, so it's worth a proper check on the drive.

Panoramic sunroof cracking or shattering

Disputed

Owners occasionally report the panoramic sunroof glass cracking or shattering with no obvious impact, one case blamed on hitting a pothole while running large 21-inch wheels, costing around £6,000 to put right. Whether that's a manufacturing weakness or just stone chips and road shock finding a weak point in tempered glass is genuinely argued over, and there isn't enough of a pattern to call it either way. Worth checking your glass cover regardless.

Viewing one? Ask this

Built from the two sections above.

Accelerate firmly from around 30mph and check the gearbox doesn't slam or hesitate through the shifts. Harsh slamming from third gear onwards points at the reported S-tronic/mechatronic fault, not just a cold gearbox.
Pull the dipstick and check under the oil filler cap on a 3.0 BiTDI for any milky, mayonnaise-like residue. That residue means coolant is mixing into the oil from a cracked block, an expensive engine job.
Look up the registration on the government vehicle recalls checker before viewing. Confirms whether the 2018 NOx/emissions recall on the V6 diesel was actually carried out, not just logged as outstanding.
Drive over a speed bump or rough patch at low speed and listen for knocks from underneath, especially on S line cars. Clunks or a harsh ride fit the suspension wear this shape's MOT data flags as its main weak spot.
Turn the steering lock to lock at a standstill and feel for notchiness or any momentary loss of assistance. A steering rack or EPS fault can show up as a brief hesitation before it fails properly.
Check the panoramic sunroof glass closely for stone chips or hairline cracks around the edges. A crack here is a roughly £6,000 repair, and it's not clear if it's a fault or bad luck, so don't assume it's covered.
Ask for the full service history including any S-tronic gearbox fluid changes. A missed fluid change has been directly blamed for at least one mechatronic failure.
