My son's 2006 XKR needs another ECM. The car got parked for a period of time, mice got in it and chewed a bunch of wiring (mostly throttle body/fuel system wires). Huge mess. And we unwittingly started the car in that condition. I spliced and soldered all the wires back together; the engine will start and idle, but no throttle response. Sent the computer off to have it checked out...they confirmed it was fried.
From what I've read so far on this forum, it appears a used replacement ECM has to be from the same year and I'm guessing a certain VIN# range. And it's not just a simple "plug and play" operation...I obviously don't have the tools for the job. Can anyone recommend a knowledgable mech in the East Texas area? With only 70K miles, it seems wrong to put it to pasture just yet. But the car's not worth investing what the dealership wants to fix it.
Much obliged for any help.

They are up East and recycle all types of wrecked Cars... I got an extra ECU from them about 6 months ago for about $450.00 as I wanted an extra.....They take Credit Cards up to $500.00...If it is over that it's COD....When I got mine they had several XKR's which had been Totaled...

Thanks, RJ237! Will try to contact Bob. Decatur is 3-4 hours away...I could trailer it that far.

 

Thanks, bcprice36 for the link! Will check it out!

 

 

Bob will also know what else is needed (e.g. to reprogram immo).

edit: I've sent him a PM with this thread URL

 

If an X100 and not X150 the eCM's pretty easy to access but you'll need a broad flatblade screwdriver.

Once out simply look at the part number on it and check ebay, I bought exact number modules for both my transmission and engine for less than £200 for both, and they both worked!

Although appreciate it may have been easier to purchase for my 96 than your 06.

 

Thanks everyone for the feedback.
zray - As best as I recall (it's been a while since we checked) the dealership in Dallas wanted nearly $5000 just for a new computer, and couldn't commit to what labor would be.

JagV8 - Thanks for giving Bob a heads up! He has messaged me. There may yet be a little life in this cat!

 

The ECM required is part number C2N3339 (XK 4.2 liter Supercharged From VIN (A40265) To VIN (A46332))
The module needs to be that part in that VIN range.

I talked to my buddy (still works for the Jaguar dealer) and he said he never had any luck with used modules for the 2003 onward ECMs.
He always got a VIN mismatch message. The older 4.0 engine cars were different and you could install a used ECM with just a simple Immobilization Setup.

Looks like a NEW ECM might be your best option.

I just replaced an ecm on my daughter's Chrysler with a used unit and just had to get it reflashed for her vin ($125). Are our jags different in that respect?

 

According to Bob in the previous post, yes, if you have a 03 or newer car.

 

It all has to do with the VID Block.

Info for ya'll.

bob

 

This is probably a dumb question however is it possible to xfer the chip containing the vid block from an old ECU to another ECU so long as it is not fried of course?

 

I don't know what the IC looks like. If it is some kinda SMT (Surface Mount Technology) that was wave soldered, I would not mess with it unless it was my own personal car.

I'll do lots of strange experimental things on my own cars but I have 5 other cars to drive if I screw up!!!

I have found a Jaguar ECU Man in Holly Lake, TX [ www. Foreign Auto Computer.com ] You can buy a XK8 or XKR rebuilt ECU or have yours rebuilt or reprogramed for the security system in you Jag...! This is the best one I have come across and it is in Holly Lake,Texas!
Holly Lake, TX is in N/E Texas.....up around the Canton area...………….1-800-241-6689
