Happy to do your OBD whenever as well.

You almost certainly have a boost leak
You need to do a boost leak test.
Search the forum for how-to.

The car is over boosting. I checked it with a boost gauge. I bought a spring from 034 but looks like they supplied a 2.2bar absolute pressure spring. I am sure this is the problem. What is the factory documented spec for boost.

2.1 absolute they say:

Put a stock spring in it or get a remap to suit the stronger spring.
