[Mk2] [Turbo] Boost problem

Post by neilgam1 »

Hi have a boost problem.When car heats up it still boosts the same as when cold and idles about 1000-1100rpm. If you let the car idle for a minute or two the car will then boost full. Any ideas wat could be wrong?

Could be faulty ECU water temp sensor, which is separate to your temp gauge sensor.

Will try the water temp sensor first and see what way it goes.
