Whenever I start my Audi A4, the engine seems to shake for a few seconds before settling down. It's worrying me. Is this normal, or is there something wrong with my car?
ReplyThis shaking is a common occurrence in Audi A4s, and is known as 'cold start misfire'. It is not a cause for concern and is a normal function of the car's cold start system.
It is likely caused by deposits and build up in the engine's fuel injectors. A professional cleaning service or using a fuel system cleaner can help resolve this issue.
