Im a new member. Have had an A4 (B9)for two years its well serviced and in good mechanical condition. With the start of the cold weather at switch on numerous warning lights appear some staying after engine starts. The car will run OK with no obvious driving problems
Residual lights are usually Tyre pressure, cruise control ,abs, and engine warning.
Battery is New, Resetting the fault codes using a diagnostic unit from my local garage works but the faults re appear.
Any suggestions
