I got a code today 00665- Boost pressure regulation control range not reached  :sad: Reading into what others have suffered it could be anything to do with the turbo. Including pipes, egr valve, wastegate etc so still not quite in the know but getting there i have said take it back to the garage the work was done last time and see if they can work it out with this information  :smiley: cheers for the link  :smiley:
