Hi I just changed fuel filter on my audi a4 1.8t, quattro, 2003, and after I changed it car won't start. I also vent the fuel injections but nothing happened. Can you tell me what can I do or how to fix it, so my car will start again? thanks,rado
You have the fuel and vacuum connections reversed on the filter.
