Title: 2.5td omega elite estate won't rev
Post by: maceanruig on 13 September 2007, 15:54:25

Hi there, I'm brand new , been recommended this sight by phate???. I just bought a '96 2.5td elite estate which I drove from Gloucester up to my home near Dundee. The guy I bought it from said it had been sitting for a few months (try a year and a half!) and that he had put contaminated diesel in it which had destroyed the fuel pump. As repair was going to cost over £600 he bought another one off ebay. But he thinks it is the wrong one. With no load the car will rev to about 3700 and on load to about 3100. So it was interesting to say the least coming up the road. But to be fair the car ran like a dream apart from that, with the only problem I could see being the warning for the windscreen fluid which  doesn't go out even now I've topped it up. A friend suggested the problem might be a sensor, I forget what he called it near the top of the pump, but I disconnected it and it ran the same. Anyone any ideas? Sorry that I've been so long winded!

The windscreen one is easy - that'll be level sensor in side of bottle.

The engine....    ....is it smoking excessively?  Check fuel filter is full of diesel.  Empty diesel out of fuel filter, and fill filter with 'Diesel Magic' and let that run through (might run a bit rought for a few secs).

I'll have a think.

Glad you took my advice of joining. I am sure someone on here will have an answer for you soon. Hopefully the costs wont run as high as £600  :o

I'm not a diseasle person... However, I have dabbled a little, who fitted the pump?  Has it been timed up properly, is what I'm insinuating!   Also injectors maybe a little cac'd up...

am i missing something? i thought the pump had to be matched to the ecu,ie you cant just change pumps willy nilly.did we not find this out with the tractor?

From what I can gather, if the pump is newer than a certain date, and the ECU is older than a certain date, it won't be happy...   ...its in BMW TIS, but cant find the article at the moment...

I'm not sure if this is the correct way to respond. Thanks to The Boy for the advice. I unscrewed the nut from the bottom of the filter - there would be water in there if that's the problem? Haven't got the diesel magic yet. I'm just a bit wary off taking things off in case it stops the whole shooting match. To add it do I just undo the big screw on the top of the filter? Also the water bottle sensor. Of course the water bottle would be hidden deep in the bowels. I took the front grill off. I take it the cylindrical thingy to the left with the electrical attachments and a water cover thingy is a motor. I felt to the right hand side and thought I could feel an electrical connection is that the sensor and is it simply a case of pulling it off - if you know what I mean!

The washer sensor is in the left side of washer bottle - much easier to remove bumper tbh...

To fill filter with diesel magic, unscrew entire filter ;)
