With a national DVSA MOT pass rate of 77.26% across 264,162 tests, the Audi A4 demonstrates a solid, if not exceptional, performance on the UK's roads. This figure represents the percentage of cars that passed their MOT test, and it's important to remember that such statistics reflect vehicles presented for testing, not their overall lifetime reliability. Failures often cluster with a car's age and how well it has been maintained, rather than being an inherent fault of the badge itself. The most common failure category for the Audi A4 is 'Lighting & electrical', accounting for 27% of all failures. This typically means issues with bulbs, indicators, or wiring, which are often relatively inexpensive and straightforward to fix. Following this, 'Tyres' contribute 20% of failures, highlighting the importance of checking tread depth and general tyre condition. 'Suspension' failures, at 17%, suggest inspecting shock absorbers and springs, while 'Brakes' at 14% indicates a need to check pads, discs, and fluid levels. For anyone buying a used Audi A4, these common failure points offer valuable areas to scrutinise before purchase. A thorough visual inspection of all lights, a check of tyre wear, and a test drive to listen for suspension noises or uneven braking could save future hassle. Currently, there are 3 Audi A4 models available on Motoring Today, with prices starting from £10,990 or a representative monthly payment of £256. Finance is, of course, subject to status.
