Hi,
I've diesel magiced it, as per the boy, I've checked the fuel filter for water - none. I've had it diagnosed - nothing showing. Looking under the bonnet I notice an electrical connection to the battery, blue that runs to a 15 amp fuse near a box with ZF on it. I'll replacethat soon as I get a connector. Also looking in the fuse box thingy under the bonnet I notice that no 1 relay is missing - maybe its supposed to be. Does anyone know what its for? A stupid question - of course somebody knows. It goes into a purplish connection. The car is a 96 2.5 td elite estate.
Thanks, john

As for missing relay, see relay box layout posts in Tecnical Information section.

Is the pipe from the bottom of the inlet to the boost pressure switch OK?

Yes i think the guy who did the diagnosis fouind a propblem with this but sorted it and made no difference.

According to Mrk DTM Calib its a test connector.

Nothing plugs in to that then

Is it smoking a lot either at idle, or when booting it?

Check the inlet track from the airfilter, to the turbo, through to the intercooler and into the inlet....make sure that none of the pipes have come off.

No

Hmmm, out of ideas at the moment.  Hopefully one of the diesel experts can suggest something...

Hi
What year is the car? I seem to have the same problem with my 2.5td at the moment but my car is a 95 vintage. Mine does not appear to be maturing gracefully!!!

Try looking under the pellum ( not sure of spelling) chamber - the large aluminium air intake that sits on the RHS of the engine. Between the underside of the second and third air intakes there is a sensor - unclip the electrical socket and try the engine again to see if that makes a difference. Leave the sensor in the casting. I believe it is an air intake temperature sensor. Let me know if there is any change - it certainly made a difference to mine!!!

Hi CF Mine is a 96 so I'll have a look. I think the word you're looking for is plenum which broadly is a space to allow air circulation. I'll let you know.

So you have checked all the inlet piping then?

well apart from the title anyone know what it is or isnt doing? does it tickover but not rev when pedal pressed? does it not pull under load? have i missed somthing, or what???

Hi, sorry I had an earlier post - it revs up to about 3,500 -3,700 when not under load and to about 3,000 - 3,100 when driving gets up to that no bother but won't go any higher - a pain in the arse as the auto box keeps dropping to a lower gear. A previous owner reckoned it may have the wrong fuel pump. I've had it diagnosed and he could find no fault.

There's no many bits of plumbing! Wouldn't the diagnostic chap have noticed loose or missing pipes - or am I just being naive?

Hi
After reading your posted message of today I think your problem might be different to mine experience. On my vehicle it would, under load, rev to about 2k then hesitate for rather a long time before steadily starting to rev again. It would then rev to the maximum with some effort. As I said previously, the problem was the air temperatre sensor below the plenum chamber. It is located below the intakes of cyclinders 1and 2 not as I stated before. I cleaned the sensor, checked that there was some kind of resistance and replaced it - all now appears to work fine. While doing this I looked inside the plenum chamber - it was absolutely caked in thick grease. I cleaned out as much as possible - not an easy task to do well. Also the plenum chamber is not easy to remove fron the head as it fouls the bulkhead. I did contemplate removing the studs which hold it place but thought better of it. Needless to say the car is running again and sounding OK.

sounds like a maf sensor or boost sensor fault poss air temp fault but almost definetly a sensor
