So it's  a diesel turbo.

I still don't know if it has the 6 cylinder BMW lump or the 4 cylinder Vauxhall  :-\

If it also lost rev counter then it will be the cranksensor.

Hi,
As all the other chaps have said. codes must be read first. I have had exactly the same issue on my DTI (aswell as other members).

It could be something as simple as an old EGR valve (loosing it's ability to pull the plunger up) or a leak in the small rubber vacuum pipes around the EGR valve and the vacuum pump which sits at the back of the engine.

Don't let it get you down, it will be fixable or drive round 'able' in the short term.

Keep us all informed as it all helps

On a DTi, you'll probably have P0400 or P11xx, both are "Critical System Malfunction".

In all cases, clean up the EGR, the boost sensor, and check all vac pipes (particularly the rubber elbows) for small splits.

.....and double check the large U shaped rubber coupling at the rear of the head that connects to the vac pump.  :y
