    every now and then, usually motorway driving the turbo just stops working, anyone else got the same problem what could it be?? o and turning the engine off and restarting it after a few seconds cures it....

    What engine / year / mileage / fuel / driving style etc??

    If it's a VNT on high mileage it could be the vanes sticking but you need to get it on a diagnostic first as it could be electrical, have the MAF and N75 been changed??

    limp mode and could be for many reasons.

    i recon yours could be a boost leak causing it. does it smoke?

    get it checked out on a diagnostic machine before trying to guess at what things could be wrong
