As far as I know diesels don't use a MAP (manifold absolute pressure) sensor as they don't have a throttle plate to generate a vacuum...

Or do you mean a hot wire MAF (mass air flow) sensor ?

Simon,
couldn't say if it was universal on diesels but mine has one on a little tube off the intercooler.
Citroen don't call it a MAP sensor but that is what it is. This is in addition to the MAF.
Before the MAF was changed there was also a fault code indicating a defective MAP sensor.
Replacing the MAF restored the performance and I never got around to replacing the MAP, which may well still be defective.
Possibly why my economy is rubbish, come to think of it.

The 2.5 does as it's got a Bosch Electronic pump on it, The Bosch version of the Lucas EPIC, so it will...

John, go and have a look over on Club-XM as there are a large number of 2.5 owners over there and they might well be able to help..

I can't as I only do petrol these days...

What makes you believe the MAP sensor is into trouble?

I can confirm that Jon's car does have a MAP, as I diagnosed it, and told him to post on here, as I didnt know where to get one from.
The MAP has a large alloy body and the pipe is bolted on via a banjo fixing. It is the biggest sensor I have seen
Hopefully some on ecan help, as this car badly needs it to correct a running issue.

If it's the EEC95 engine, then it's still available from Citroen (1920 3L) - £185 though! Alternatively looks like Amazon or e-bay.

The earlier one (1920T7) is NFP from Citroen, but appears to be shared with BMW - This mob look to able to supply one: http://bmwfans.info/parts/catalog/13622244674/
