This 2012 Audi A4 TDI is a reliable worry—62.7% of these diesels pass MOT first time, well below the UK average of 80%, which puts it in the lower reliability bracket for its age and mileage. The good news is that dangerous defects are essentially absent (0%), so when failures do occur, they're typically fixable rather than safety-critical issues.
With a median mileage of 123,731 miles at 12 years old, these cars have been driven hard but not unusually so, and the 0.64 average failures per test suggests wear-and-tear rather than catastrophic problems. Before buying one, budget for a pre-purchase inspection and expect that some investment in maintenance will be needed—many examples will require work on suspension, emissions, or general aging components.
The 2012 Audi A4 Technik TDI passes its MOT first time more often than most UK vehicles (86.9% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 970 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.
