weird boost problem
« on: 22 September 2011, 16:02 »
I've had a weird boost problem with my car for awhile, a few months back i got my 1999 1.8t agu remapped and it felt brilliant! couple of weeks later i drove my car and it would not go above 0 on the boost gauge (psi) i rang the guy back up and took my car back to him and he checked over everything and it was fine but try changing the throttle body, i changed and cleaned throttle body, also changed n75 valve from stealers, plug for n75 valve, boost and vacuum hoses to all silicone ones and still a problem. Another day i turned my ignition on to listening to some music for 1 min then started the car and took it for a drive amazingly i came on boost around 15psi, I've now noticed that when i go to drive my car i have to get in the car, turn the ignition on for 20 sec then start it and the car runs fine but if i don't do it i don't get no boost i don't get it?? I think its down to an electrical problem somewhere but haven't got a clue. Also i dont know anyone with vagcom

Any ideas???

No idea but it says to leave the ignition on for 30sec min before starting.

Imagine those faces at the petrol station. :grin:
