Boost issues

[Dan5481]

i have had my car recently diagnostic scanned by kwik fit and after the scan my boost level seemed to dropped to standard (i have an amd remap) after 50 miles or so the car turned itself off and then went back to mapped levels. Now i have scanned the car with a copy of vag com that i have and it will not scan the car, it just stops responding????
The boost level have now dropped aswel from he remapped level and ideas??

You may have more luck if you post in the correct section for your car and let us know what model/engine etc.

I would repost in the audi section...Try checking all the little vacuum pipes connecting with the turbo and check the large intercooler pipes for leaks.
