Yesterday when I tested the passenger side pump it was running 15-20 sec, then the engine stopped, during the testing the driver side pump returned to normal It.druw 8 Amp. The car is running fine today, the same thing happened 6 months ago ,I drove the car 3000Ml then it acted up . Why is the pump acting up occasionally ,as a DC motor either it is working or not , why is it going mental in a 6 month period? do you have any other suggestion beside replacing the "good running pump".?
How the two fuel pumps are synkronized? why only one pump is running continously. ?
what is the reason vw using two pump instead one .?
