| Description of the problem | Starting at around 130,000 miles, when gas tank is at a quarter or slightly less, the car looses power and acts as if it is not getting fuel to the engine. When this happens while driving down a highway at typical highway speeds, power is lost for 10-15 seconds, rpm drops to around 2000 or less (while in "drive"). Then all of a sudden, the engine jerks to life, and i can drive the car normally, up until i have to refill the tank. The stalling doesn't repeat itself until the next quarter tank. When the quarter of a tank issue happens in the city at slower speeds, the car dies, dashboard engine lights come on, and i have to pull over, and crank the starter 3 or 4 times, and eventually, it starts back up again with normal driving resumed. One time i was driving up a hill, lost power, and had to pull over quick. When the quarter of a tank issue happens while parked, engine at an idle, the car dies, and i have to crank the starter a few times to restart the car. This problem only happens once per tank cycle, only at the (approximate) quarter of a tank position, and doesn't happen between the full to 1/4, or the 1/4 to empty phase. I know i am not out of gas, as i'm filling up the tank to normal levels. The fuel pump has been replaced twice, and the fuel filter once. My mechanic charged $80 to diagnose the car, only to find a code about a spark plug that misfired - which of course will happen during fuel starvation. Spart plugs replaced, but the problem happend again. I've called 3 or 4 vw repair shops, and nobody has a clue how to fix this, especially when i bring up the quarter of a tank issue. The only way to prevent this from happening is to fill up before hitting 1/4 tank. Irritating !!!! Issue going for about a year now. |
