Engine hunting after fuel filter change |
|
Just serviced my 2006 D3 and for the first time I've changed the fuel filter (130000kms) turned it over after fitting the new filter and it ran for a few seconds then stopped. OK - so there is air in the system, so I found the bleed valve on top of the engine and purged it. OK - engine starts and idles fine. Took her for a spin and now the engine "hunts" on acceleration at about 2000 revs. Again I purged the valve, but no air.
Anyone know if there is any more bleed valves ? or other way of getting all the air out of the system, or have I kicked off some other fault ?
Any help would be greatly appreciated
Thanks
Phil

Hi roastbeef (Great name )
Worth checking the pipes have been put on the correct way , easy to make the mistake and this would cause problems. No more bleed points btw

Hi
Did you use an original filter as sometimes after market. Filters can cause problem s
Did you cycle the ignition 30 times without starting if not you have got air in the system
Cheers

The D3 is a self prime system with a spill off back to the tank., I would go for its sucking in air make sure the seals are all ok and the filter bowl is on good and seated well.
I have changed loads of fuel filters and never had to do anything special just turn the key on waited 20-30 secs before starting it.

This is one of two things first check the high and low pressure hoses aren't crossed and if this is correct change for a new filter genuine spare.
Had this issue you describe and the filter solved it
Hope this helps 2007 D3 HSE Artic Frost Silverish

Hi
it is self prime but a LR. Tech told me not to crank it to get the fuel through
but to cycle the ignition 30 times as there ids primes the system for them

Thanks guys, I changed the hose connections today just in case I'd got it wrong, but no, that made it MUCH worse. So it must be the filter - it was a Mann filter (yellow and green box) so I'm of to the dealers tomorrow to get a genuine one.
Cheers
