What should I look for in a used Audi A4 saloon?
Generally this generation of Audi A4 is reliable, but there are some issues.
The 2.0-litre diesel models can burn oil over time and some owners don't check the level, relying instead on the oil warning light. This is dangerous, and could cause permanent engine damage. Consult the service book to find out when the oil was last changed, and then check the dipstick to see if it's low.
