On the safety side, the most frequently flagged dangerous fault is tyre tread depth below requirements of 1.6mm. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired.

A typical Audi A5 S Line ED 1 40 TDI QUAT S-a owner drives around 7,950 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.
