Diesel fault, recommended refurb diesel injector companies?
Discussion
I'm after some advise if you lot can help me out at all.
Does anyone have any experiences with diesel injector companies which sell refurbished diesel injectors?
I've found a few companies and as always there are some great reviews and some terrible reviews for all them.
I was wondering if anyone has used any companies that have been great and they would recommend? If so who?
The fault I have is:
2008 Citroen Dispatch van with a 1.6 HDI engine in it.
When the vehicle is warm and has been driven for 10-15 minutes, when underload (pulling out of a junction or accelerating) the engine light comes on, the engine starts to knock, smoke heavily, (it occasionally revs itself), then cuts out.
The fault codes stored are 'high pressure fuel pressure' too low.
If you clear the faults and leave the van 5 minutes it starts up straight away and runs with no issues.
So I suspect one injector is intermittently sticking open or leaking, dropping the fuel pressure and putting unrequested fuel in the cylinder causing the smoke, knock and revving.
This is a very intermittent fault, I recently took my van out for a 40 minute drive and it only happened once in this time.
I've done a leak off test and all injectors are ok

Hi Moopig, I purchased a 2003 Peugoet 406 HDI estate, I was told it needed injectors, did a leakoff test, no leakoff, had some oddball fault codes, so wrote them down and cleared fault codes, car would run badly, then cut out or rev itself up and slow down at will!!
Very strange, put my scanner on it and studied lots of data, recording some of it to study, and found fuel pressure rising and falling all by itself, no input by throttle pedal or anything, was a bit stumped at 1st, anyway looked at the fuel pressure sensor wiring, it was sheathed in that hard plastic tubing, very carefully pulled it off, all 3 wires to the fuel pressure sensor had no insulation on them and were touching each other, causing the car to rev up when the 5 volt wire touched the signal wire, or stalled when 5 volt wire touched the 0 volt wire.
Took the suspect part of the loom off, replaced with some quality wire, put it back together, problem solved, car has been perfect ever since now on 166K miles.
OH and I paid £165 fot it 3 years ago.
So far the cheapist car I've ever owned.
I hope that gives you something to look at, it may not be that but it could be worth looking at.
Good luck.
