1998 Audi A4 1.8T FWD - Just Keeps Dying
Hi Guys. I have a 1999 1.8T FWD MANUAL. We cannot figure out the problem with the fuel supply. The car has had an UPSOLUTE chip soldered into the ECU 6 years ago and no problems for 2 years. The car has had 3 fuel pumps, 3 fuel filters, cleaned gas tank and the problem still persists. The car just dies when idling like the engine cannot get fuel. The first 2 times, the fuel pump was busted and so we replaced. Before putting the 3rd fuel pump, we cleaned the gas tank to make sure there were no sediments causing pump failure. After using the car for about 1 month, the car died again with the same problem. I am starting to think that the chip is causing this problem. Any ideas?
