Revs holding and dropping
Hi. Having some serious problems. I have just replaced the turbo and egr. As before I was having problems with not getting over 40mph. I've reassembled the car now. I have taken it for a spin when once again been loosing power whilst driving. I parked up raised the revs to 3000 held it for couple of minutes and there it was. It started to reduce my revs. It sounded like it was great 1 minute and the next like the revs were being jumpy. No lights flashing at all. Soon as let off the pedal and reapply the power is there again but does the same thing over and over at different held revs. I'm at the end off my tether and need some serious help please. All filters changed. Banjo clear. No loss off coolant. No hold light of or flashing. Nothing. Any help appreciated.

I think you need to have an other go at the filters and your fuel tank. You could also use a test bottle with fresh clean fuel making sure the pump filter is perfectly clean.

On my year 2000 variable vane turbo, just one of the turbo solenoid valves caused me power loss. First replaced with a second hand valve, which was worst (almost permanent power loss) and then a new one. I have had no further power loss since this fix.
What makes you think it is the turbo itself? I have been told by at least one specialist they are quite reliable. If you've got warning lights showing they should help you determine if its a problem with the Engine Management System.
In my case Premier Bongo have always found that the two warning lights I had showing have always been as a result of a faulty Turbo Solenoid valve.

How can I find out if my fuel pump needs replacing
Re: Revs holding and dropping
Not sure if you've checked this - there's a small pipe from the elbow on the inlet manifold, to the top of the diesel pump. Check it's attached properly and not split.
Also, is this pipe is oily?

Problem solved... I took the sender unit off today and inside the bottom was some serious carnage. In the tank there were bits of leaves and plenty off bits and bobs floating around. I took the pipes of the diesel filter and blew them through with a compressor. Cleaned the tank out with Karasene and then put some lovely clean diesel in. Put all back together and runs like an absolute dream. Bongo love
