I have a 2009 GLI TSI that I've had chipped for about 9 months. The fuel pump keeps going out on it. I'll get down to a quarter of a tank and the car will shut down. First time it happened I took it to the dealership and they fixed it but 5 months later-now- it is happening again. I can put fuel in it and it's fine but it's just when it gets down low it shuts down again. Even if I take the performance map off and put it back to stock it still does it. If this problem is due to the APR tuning I need know because if it's not I need to trash this car. Has any one else ever had this problem???
