OK, will wait bit longer.


 


More info:- when turn car off then restart, it clears completely. Also taken cowl off engine - there's T piece pipe from turbo to airbox, centre of pipe goes back to centre of engine opposite oil filler cap which has broken clamp and wasblowing oil out. Could this be cause or electrical prob? Turbo appears clean and no wear visable on propeller.

Hi,my name is mike and I will do my best to assist you with your question.
Before the vehicle goes in to limp mode does it run normal?
Customer: replied 4 years ago.

yes runs perfectly normal, then revs drop like stone - bit scary when overtaking and my babies are in car

Expert:  Mike Kelly replied 4 years ago.
Ok the issue that you are describing is a turbo issue. This is consistent with the turbo falling under boost,this can be from the turbo boost valve sticking or the turbo impeller bearing sticking at times. The best way to check these is with the use of a scan tool to monitor the turbo performance while driving.
