Hi dear, My car is an audi A5 convertible, S line TFSI, 1984cc, 2009 model. I have experience something that have occurred about two times whilst driving. My car engine came to a stop while driving. But all the other electrical components like lights, air conditioner, stereo are still have power. I switched the engine off and turn it back on and the engine starts running again as normal. I have station the car and left the engine to run and the engine didn't stop. I don't know what actually going on with my car. Can someone share with me if they have encounter such, or they know the how to solve this problem please. Thank you
