Before you view it

What to check before viewing

The Audi RS6's most common MOT issues, turned into things to ask about or look for.

Brake pads

High priority

Ask when the pads were last replaced and check the warning-light history.

Tyres

Worth checking

Check tread depth across the full width on all four; uneven wear suggests alignment or suspension issues.

Vehicle-specific check

Worth checking

Check the car’s number plate on MOT Wise to see its own MOT history and any recalls for its build years.

Windscreen

If you have time

Inspect for chips and cracks in the wiper sweep area (Zone A) — these will fail an MOT.

Each row is one generation of the RS6, shown at the age printed under its fail rate. So rows can be different ages. Fail rate is the share of MOT tests that ended in a fail, retests included. A rating is given only when there are enough tests to place the fail rate in one rating band with 95% confidence.
