Hi Guys,

I have a 2007 Audi Q7 3.0tdi (BUG)

Sometimes when driving goes into limp after car is warmed up (no codes on dash) plugged it code reader getting the following:

"Control circuit for controller for Turbocharger 1 (J724): Electrical
Malfunction P3348 No Signal/No communication - Intermittent

Boost Pressure Regulation Limit Exceeded (Over boost Condition) P00234
Upper Limit Reached

Any body experienced this or has a good idea how to resolve?
