Hi just to comment what recently happen to my car, I got water on my fuel tank, I assumed it was the petrol that I filled, but the point is I have to take my car to the dealer because it did not acelerate above 3500rpm... so I was told that the high pressure fuel pump was damaged, so they change this and pressure regulator just in case, I give you the part number changed, and I doubt they do something else, but this is the main reason I am writing this, because the hesitation is gone and I do not know if it was something with the pressure regulator or the pump... and if these parts has something to graduate ?
the part numbers:
71739713 fuel high pump
what I noticed now, is that my fuel consumption goes up like 1 lt, example I was doing on the city 12 lt/100, an now 13-13.5
