Hello, I have an audi S3 8l 2000 APY engine and I'm facing a very frustrating problem. The car was driving just fine but the last month or so, sometimes the car as soon as I turn the key, the dash lights and indications will start flickering instead of being steady and the car won't start or will start after many tries. Also, if the car does start and I turn it off and on again in a short period of time, it won't start at all even if I try 5 times. My mechanic cannot find what causes the problem, and I'm desperate for solutions. Do you guys have any ideas? Thanks in advance
