On the safety side, the most frequently flagged dangerous fault is tyre tread depth below requirements of 1.6mm.

A typical Audi A4 Technik 35 TDI S-a owner drives around 10,519 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres.

Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
