Vauxhall Vivaro 03 1.9d - Carrow
Hi all, can anyone help with a problem on the above vehicle. It will only rev to 1500rpm, the fuel filter has been changed but with no difference. A diagnostics check has shown no fault (although not a dealership check as they were too busy).

Any thoughts or suggestions gratefully appreciated, my friend is tearing his hair out!!

These modern diesels are too complicated for 'poke and hope'. It needs to go to a main dealer for proper diagnostics. It can go to a Renault garage as it's the Renault engine in these.

UPDATE: A disc from the egr valve had come away and lodged itself somewhere, partially blocking the intake. Don't how it happened but no damage seems to have been done & it runs fine now.
