He found air charge pressure problem and told me that it could be the turbo building up to much pressure. I found the TNG to be adjustable so I loosen the nut on the rod but realised that the rod needed to be unscrew and that the rod is held on a lever by a clip. It's a tight fit so does anybody knows if adjusting the rod would cure the pressure issue, I wouldn't want to waste a day working on the turbo. Thanks for your help
PS : I didn't read the codes on the Vadis software

the VNT rod on the turbo is factory set matched to the individual turbo , if you tamper with this you will alter this calibration and will need a new turbo anyway as the air flow wont match the expected and will get the MIL / message up again!
