Before you view it

What to check before viewing

The Audi A6'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.

Brake discs

High priority

Ask for the date and mileage of the last disc replacement; visually check for a deep wear lip and rust pitting on each disc.

Tyres

Worth checking

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

Suspension bushes and joints

Worth checking

Listen for knocks over speed bumps and ask about recent control-arm or anti-roll-bar work.

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.

Each row is one generation of the A6, 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.
