Per TSB 08-005-11 DEC 2010 ceramic glow plugs are no longer no longer available, replace with metalic and reprogram ECU - kit part # 68090434AA

I don't have a copy of the TSB but see discussion at viewtopic.php?f=5&t=58806 and http://www.alldatadiy.com/TSB/04/060445fu.html which also references the TSB as including an ECU reprogram and GDE says the same thing.

Perhaps when all else fails your dealer should read the instructions.

Does anyone know if the ECM needs flashing on the 2005 UK model chereokee jeep 2.8crd when fitting the new 5v glowplug kit, ive heard that the US does but when i asked my dealers service department about it they said they hadn't heard about a flash for that and had no paper work for it, they were convinced the glowplug module reduces the voltage down

You have the 11 volt plugs, no?
Don't upgrade if you don't have to. Beru, Etecno1, Bosch, Champion, etc. all have the 11volt versions for Cherokee.

Ive been having starting problems first thng now for over 12 months but fine thru the summer ? i had a new set of crap 7v VSP Steel plugs fitted Feb this year but it didnt cure the problem, so ive been checking to find other faults but i didnt know till a couple of weeks ago which actual plugs where in there as i had them fitted at a garage i dont normal use, as my mate who i use normally was in Australia for 3 months (nice), take a look at the differences in these plugs....

.................... thats why im changing got to do something to try to get it starting first thing

Isn't this a video for a VW? As far as I know, these are too short (physical length) for our application. I remember that there was a complaint about the seat (the part that seals it to the block) being very thin too.

If you have a 11 volt system, you could have burned out a few of those 7 volts plugs.

All engines for KJ 2005-2007 (so both European and US models) had "low voltage" glow plugs. 05-06 were ceramic, 07 was metallic.

Regardless of where you live, you need a new ECU flash if you have installed the new metallic plugs on a car previously having the ceramics.

I agree with you there about KJs , what i could do with is a email address direct to jeep in the US so they could contact my dealer or flash issues directed at the Uk

whosthedaddy07 - try Jeep contact info at http://www.jeep.com/webselfservice/jeep/index.jsp or get your dealer to pull a copy of that TSB I referenced earlier in this chat or get a copy from the AllData folks.

I have not seen the TSB but I know it documents the needed part numbers and it references the need for the reflash so I presume it provides information on how to do the reflash which should be available online to any Jeep dealer thru the corporate internal computer system.

So do the UK Cherokee's have low voltage 7 or 11 volt?

There are NO LIBERTIES outside of North America KJ's are called Cherokees elsewhere

Never mentioned Liberty.
whosthedaddy07 has a Cherokee, lives in the UK.
Clarification please.
