Hi all - its arrived - the dreaded replacement maf unit - fitted the unit with trepidation plugged it in checked all the other bits were in place - fired the old girl up and let her idle - seemed fine - selected drive pulled off and :D :D:D:D all working fine power there when you pull off...

hope this maf unit works when in get it - or where will this go ... from here for sale nearly good p38 nice to look at but has issues goes like a train if you unplug a few things....

Hi Dave - looked all over for one of these - oem unit £175 via bearmach - the 2218400 pierburg unit - no one can definitely say if the maf is naf ( excuse the pun) - with a fortune already spent on this car over the last month or so i'm risking £58 instead of £175 - although lots of...

here we go gave your suggestion a try --just went round the block --- disabled the egr took the pipe off -and plugged the maf back in---:ballchain: "stuff this" egr back in maff out :car: ...:crazy_driver:

ummmm no - hope this doesn't mean waste of £60 on a maf - or having to buy en egr modulator valve - gonna give it a try NOWWW -see how it goes:crazy_driver:

WOW these facts and figures are all too much for a numpty like me - lots of clever people on here - great to see - by the way i hope I'm not doing any damage to the lump under the bonnet running without the maf plugged in ( whilst waiting for the replacement to come ) BUT ITS GOING REALLY...

glad the filter change went ok - i now bow out on the pump / primer thing sorry for bringing it up - at least i will be able to change the filter without moaning next time -thanks for that ...one for wammer seen a maf on flea bay same reference as mine £58 probably try it - its new but i...

ok ta - will keep it all nice and standard get the air flow unit --- :)

not the argument - if it had a primer i wouldnt have flattened the battery trying to get the stupid in tank pump to push the fuel through - took so long to fill the filter that the battery gave up - lets have a primer - then the fuels there before we spend any battery life ... no brainer :amen:

Whoops :o - only trying to help - 5 mins to change the filter one hour to start the car one flat battery trying to get the fuel through . one jump lead assist from my old pajero . if i had a primer would have been away. Imagine the scene - range rover runs out of fuel - wife’s...

thanks all - what happens if i ignore the maf unit and pull the pipe of the egr - this will in effect disable the egr - stopping all the crap recirculating - i ran a pajero for a few years with a castrated egr ( someone took it off and blanked it ) that had no ill effects .. looks like...

i'm no expert but it is easy - but i didn't do it properly make sure to fill the new filter with fuel before putting it back on - there's no priming pump on the filter housing ( most of the jap cars have a pump to prime system after a filter change , these expensive top of the range cars don't...

ok Lads - yesterday looked at the maf unit give it a wipe - looked at the egr valve gunged up took it off really good clean checked by hand that it was not ceased in any way seemed ok - fired up after the clean test drive no difference . today changed fuel and air filters - test drive - no...

Changed the filters no difference - so took advice from one of your comments :):):):) --- unplugged the maf unit WOW :eek::eek::eek::eek: pulled like a train -thank god for this site - hopefully the maf unit will put it right ..thanks all

thanks all - i must say its great to get all this response to what must be a common problem to this particular model with the 2.5 engine ( guy who had this before me had it from new and only his his wife drove it ,had loads spent through its life on running repairs service every couple of...

so the pump ??? if faulty is it likely to not give enough fuel through - eg starving the engine like tickling the throttle instead of proper levels - until one day finally failing -- if so why am i able do full top speed - don,t compute - wouldn't it cut back through lack of fuel at high speed...

how do you know when the tank pump is iffy - is it try it just in case or is there a definite answer - i notice the previous owner had put a non return valve in the fuel line so is there a previous pump issue with the car - Going back to the core reason for this - if the car is sluggish and...

sorry - meant that it was slightly dirty but not as gunged not dusty - mileage about 70k so may need a looking at - gonna get my spanners taaaaa

Hi again -just took the flexi cooler pipe off to look at the condition from the egr valve end - the valve area was all bunged up a bit but the intercooler pipe going to the valve, and the outlet of the cooler (with the pipe off that end) seemed quick clean a bit of dust on the rag that went...

sounds like a bit of a task - will have a look thanks
