Hi all looking for some much needed advice. Have a 2006 2l diesel with 99k miles on the clock. Recently lost power but turbo working ok. It seems it just isn't generating the power on the other end. Checked the pipes and no splits etc. Checked the vacuum valve and thought this was the culprit so replaced it and still nothing. Dpf light flashed for about 20 mins on a motorway run but then disappeared. No other lights on dash. More recently it has been running very rough on cold starts although not sure if this is related to the power problem. Any ideas??

 

Remove the DPF, go for a drive & see if the power has returned. ( Yes it will be very noisy)

 

Cheers grim_reaper. Don't think dpf problem though. Had pushed the waste gate arm and it gave us a boost. Seems the turbo boost valve isn't sucking though

 

Hi, what was the outcome of this please?
