This 2015 Audi A4 diesel is a concern: its first-time pass rate of 61.1% sits well below the UK average of 80%, meaning nearly four in ten fail their MOT on the first attempt. The good news is that dangerous defects are essentially absent from this cohort, so safety isn't the issue—it's recurring minor niggles that catch owners out.
With a median mileage of 93,710 miles and an average of just 0.33 failures per vehicle, these cars are running reasonably hard for their age but typically rack up multiple small problems rather than one catastrophic one. Before buying, budget for pre-purchase inspection specifically targeting electrical and fuel system niggles on the TDI engine, and expect to spend on remedial work before MOT if you pick up a second-hand example.
The 2015 Audi A4 Ultra SE Technik TDI passes its MOT first time more often than most UK vehicles (91.2% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 761 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
