BogMonster Posted December 3, 2005 Share Posted December 3, 2005 Start the engine and let it idle don't rev it AT ALL or it will stop and then you will have to bleed it!! It will idle for about 5-10 sec then you will hear the revs drop slightly and it might "hunt" a little as the air is purged from the system, then the revs will pick up again and once they have, Robert is your mother's brother If the vehicle has a sedimentor bowl you can bleed that in the same way after draining/cleaning but I am told you must not do both at the same time or it will die, i.e. clean sedimentor, let it bleed and run for a bit, then change fuel filter, and bleed again. No pressure in a Tdi fuel system. To be honest even on petrol EFI systems where there is pressure retained in the system, it's much easier to just hold a rag round the union when you undo it, than arse around with the "ofishul Land Rover fuel system depressurisation procedure" - all you get is a "ffft" when you loosen the union and that's it Quote Link to comment Share on other sites More sharing options...
