Title: Intermittent boost loss
Post by: Lukesheehan on July 25, 2023, 06:29:04 pm

Hi looking for some advise if anyone has had this fault before. The car will drive fine but intermittently will lose all boost. If I turn the car off then on. The boost returns and will Drive fine again. No engine lights come on. And there are no codes logged. The dv has been changed along with the hpfp. Any help would be greatly appreciated thanks.

Mine did the exact same thing 6 months ago. Vcds came up with an over boost fault code. I cleared the code and hasn't done it since.

000564 - Boost Pressure Regulation
               P0234 - 001 - Limit Exceeded (Overboost Condition)
