Hello I have a problem. My TT engine loses the pressure at 4 and 5 gears after 7-11 sec. The engine first makes over 1.5 bar overboost then it jumps to 1.2-1.3 bar and then it goes up to about 0.6 bar when of course I press full throttle all the time when let go between time gas for 2-3 sec. then it builds up pressure again. I was able to pull up the 4 gears to 230 earlier without letting go of the accelerator, now I have to let go a few times gas pedal to reach 230. Someone knows the problem.. And I also constantly get the ignition coils capput. I only changed the car for 1 year but I already changed 4 spouls. One coil even lasted only 4 months. Someone had had had it already.
