My 2004 Audi A6 Quattro Turbo 2.7L ..My car will start, but won't run long.then just shut off, ,it will restart, ,what do you think it is,,,,I have heard from it being the ECU,,fuel pump, fuel filter
The ECU is allot of money, check to see if the injectors a leaking also check the pressure at the rails as well change the fuel filter. Then have the ECU tested..
