I had a problem with my Audi A4 1.8 Turbo 2005, it seemed that they were the injectors because I was unstable and spent a lot of gasoline, in the end I looked online and stopped with the fault, only a pressure valve, it cost me $ 850 pesos and I save myself to the workshop.
This is the video that made me save a money !!
Greetings and luck !!
