Cooked ECU

Unless there are topside switch failures, or check sum failures I'd be putting the ECU replacement on the back burner until everything is checked out.

Add: what I'm thinking about is something like mturri's experiences on this Td5 D2. He was getting long lists of injector open and short (same as high//low) which was finally traced to a rubbed harness. See this d2 thread: http://www.aulro.com/afvb/discovery-...e-harness.html . I'm not sure what the rub points are on a defender but I'd think full inspection from ecu to the injector loom plug would be in order.

Forgot about that part paul....

I like the harness idea, I have seen this also but didn't cause those huge faults like the OP

I spoke to the bloke today and politely asked him what the fault codes were, and he got very defensive that it is the ECU.

Two he mentored were injector open circuit and something along the lines of 160 can fault (?)

I'm away with work till Friday but have told him that I will probably pickup the vehicle and mull it over while I stockpile some coin. What I think I'll do is take it to KLR automotive in Kingsford. Hopefully if it is the ECU they will be less than $2000, I'll give them a call tomorrow. Cheers

If I decide to take it via home insted of direct to KLR I will inspect and test the loom with a MM. My background is electronics technician, so I'm happy to do this but the mechanical stuff is way over my head :-(

well don't forget to ask us plenty of questions then! many a vehicle has been repaired and owner been educated in the process on this forum !

a great sense of accomplishment doing things yourself, and lets face it getting to know your td5 or any other landy for that matter is great fun indeed!

So I picked the car up this morning and took it to Brad at KLR. Like most of you he also didn't think it was the ECU at first, but rang me this afternoon and confirmed the ECU was at fault!

He was able to put the new one in same day and I'm back on the road! Happy days... Fortunately he was cheaper than quoted at the other place and we chatted about Land Rovers and mods etc for half hour or so when I picked it up. One satisfied customer!

When I bought the car I said to myself that I would stash a small amount of money away for repairs due to fine British engineering, but didn't think I would be up for $1500 in the first month! Hopefully no more problems for a while...

Cheers all for the help.

I suspect that i am by no means the only member on this board that is really pleased to hear your good news.

Not only did you get further confirmation that your problem was indeed the ECU itself that was fried, but at the same time you got a cheaper quote for replacing this.

I would certainly join in your hopes for no more problems, however, i guess someone must be the devils advocate and as such i must point out that TD5 ECU's are not exactly well known for self destructing.

We would all feel really bad if whatever destroyed your old ECU destroyed your new replacement.

As such i would advise that you still follow all advice in respect of checking possible problems that the many fine members of this board have advised.

If you can retrieve or ask Brad if he's still got the old ECU I would be interested in having look at it - happy to pay postage. I've been doing a bit of work on the ECU software, but need an ecu that I can use for tracing circuits without having to pull the ecu out of mine. Doesn't really matter if it's completely cactus for this purpose.
