Did you fix the faulty EGR valve? If not, I would be looking there and getting it sorted. And may need to clean the inlet manifold out, probably gunged up (I recall you posted that the MAP sensor was well and truly cacked up, the rest of the inlet system will be just as bad).

the inlet manifold is not dirty its fairly clear once its warmed up it runs perfect and has been ok since the last cold snap in november the map sensor had not been out and cleaned since vehicle was new 135000mls ago only now its gone cold again its playing up again ,also nothing showing on diagnostic tablet . i spoke to local land rover mechanic about egr he said the way ive disconected it only direct air passing through so no recirculating , must be a sensor i might try cylinder head temp or. water temp sensor as these apparently control ecu fuel/air supply
i took out new map sensor and its still clean as new,
is this the land rover experience thats talked about 😂😂😂😂
 
Thanks for your help
windblower i started her today frosty morning ticked over for 2 minutes then stopped i restarted and sat there holding 1500 revs till temp guage moved up to minimum let her tick over and went out she ran perfect its a sensor but i dont know wich one coud be head temp or water temp or ? another that sends message to ecu sorry to be a pest i may have to take it to someone but i can usualy sort things i just rebuilt engine on john deer tractor ( no stupid sensors ) is this progress i wouldnt touch the wifes new car
by the way wheres the vcv valve

its worth a try but today fuel level in tank went below half and it ran awfull i filled to the top and it ran well ,i wonder if its sucking a bit of air on tick over but better when revving im going to inspect the filter fitting ,long shot but hey ho
 
Could well be the root cause of the problem. I think the 2.4 has an in-tank pump as well as the pressure pump on the engine - but that might be the 2.2 model - will check later. Long time since I looked. Could be a build up of muck in the tank around the pump? Also how long ago did you change the fuel filter? Mine began to drip as it got a bit of corrosion from the outside due to how long I left it. There is a thread (or two) in the Puma engine section from a few years ago, dealing with bleeding the system after a filter change. Should be easy to find it, there ain't too many threads on this model engine.

Checked. 2.4 does not have an in-tank pump. The high pressure pump (on the engine) incorporates the low pressure pump.

ill change filter tomorrow i fitted the one on it in november i recall it was hard to push up and turn maybe just maybe the locating lugs may not be lined up ,the tank was full to top to save priming and next day it ran perfect but got worse as tank level went down it might be getting a bit of air on tick over and ok when revving 🤞
 
I do recommend filling the filter with fuel before fitting it. Otherwise there will be a lot of air in the fuel system - unless you bleed it of course.

hi windblower just thought id let you know the problem i had we changed fuel rail pressure sensors and valve on the pump then had to do a relearn with computor dont know witch one was causing problem so changed the three to delphi parts it took a bit of starting after but eventualy got it running seems ok now after a week of driving bloody nightmare but thanks to your imput i spoke to a transit chap who said its a common fault with them so fingers crossed 👍

yea haynes defender manual says you cant change pressure sensors on common rail you must replace whole rail but transit manual says you can same engine i think LR tell them that so to make on spare parts 😵‍💫. future reference for other parts eh
