Hi all,
Thought I'd post to see if anyone has any advice. Basically have fault code P0234 over boost issue.
Believed this was down to the map sensor and previous owner provided new Bosch map sensor (however not 100% sure this is genuine). This did not sort my issue and have change a few of the common problems to see if this sorted. This included new PCV, dv and N75.
I'm thinking whether it could be down to a non genuine map sensor and thought see what others think.
The car is a gti dsg. Car runs sweet when driving fine and boosting hard and then boost just cuts out and car goes into limp mode. It's very intermittent and no real pattern to when it happens.
When this happens if you turn the car off and back on again, boost is back and car drives as normal.
Any info is much appreciated
