This car is the 109 dpf model.

I've spent a fortune on this problem resently. Its been in and out of my local independent garage so many times I've lost count.

The car has intermittent boost presure. When pulling away from a standing start it has'nt any turbo boost at all, but when the engine is running above 1500 rpm at a settled speed the boost can kick in like it should if I need to accelerate, but not every time!

The car has done 90,000 miles with regular full service history.

Parts I've had fitted include the following.

New Turbo, New DPF, New Thottle body, new fuel filter. new airfilter and new egr value.

The engine management light works, because it comes on then goes off like it should when I start the car but it does'nt come on to show this fault! My mechanic has been using his 'Snap on Solex' computer to look for faults but can't find any on that either.

I've also noticed in the last week or so that the engine cooling fan is on and working hard and is often still on for another 2 minutes after I have finish driving the car but the Temp gauge just reads normal! The engine cooling fan never used to be working as often as this during the summer months!

I'm sure all these parts I've had were'nt necessary and i've fallen out with 2 garages over this.

I've either got a very bad car or the mechanic's don't know what their doing!

If anybody has come accross this problem before I'd be glad to hear from you.
