Hello an thankyou for excepting me to the group. Currently having a problem with my wifes qashqai 1.5dci.

Long story short engine went it to limp mode on her an after investigation turbo was caput so brand new unit fitted dpf chemically cleaned new filters oil the lot now runs sweet but just wont rev up properly like its in limp mode still an like theres not boost. An if you drive it a short while the traction control light comes on, on the dash but not faults logged. Thought it could be blocked exhasut gas pipe with sensor. But not that as not blocked an tried new sensor. Tried new vacuum sensor an not different. So wondering if it could be boost leak??? Any info would be appreciated. One last thing is i have monitored the throttle percentage on the computer compaired to rpm an it only gets to 20% when foot to the floor an randomly drops off even wheb revs are still at 3000 rpm. Could this be a throttle position sensor fault or does it do this in limp mode as to reduce rpm.

Sorry for the essay an thankyou again
