2024 Audi A6 — MOT failures & pass rate
493 MOT tests on the 2024 Audi A6 are in this dataset, and 97.4% of them passed. Executive cars of a similar age fail 4.9% of the time, so this is 2.2pp better than the group it competes with. Failures cluster in lighting & signalling, tyres and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (2.8%) and tyres (1.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and hydraulic brake callipers — headlamp aim alone was recorded 22 times.
Mileage matters less than usual here: the 2024 A6 fails 1.7% of the time in the 0-30k band and 0.0% at 60-90k, a spread of only 1.7 points.

What to check before buying a 2024 A6
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 2.8% of tests. Start there.
- Lighting & signalling (2.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (1.6% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (0.6% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
