New ECU !!!!! You're Kidding

[Bugman]

Hello again,

It seems things are going from bad to worse for me. You may remember this original post about a new main wiring harness loom in the Extreme TD5 as a result of the oil leek.

http://www.aulro.com/afvb/showthread.php't=34061

Well after two weeks at the stealer in Launceston they're now telling me the car still isn't going and they're talking possibly buggered ECU.

Apparantly the codes are showing an engine fault (and for the life of me I can't remember which one now). But when they've independently checked that fault they've found no problem. They can't clear the fault and are now pointing the finger at the ECU and even asking if I want them to order in a new one. No!!! that's for sure.

It's actually a Bruce Davis ECU fitted by MR automotive in Brisbane but the car is now in Launceston and I'm in Hobart. It hasn't been easy.

They're telling me they've sent off the diagnostics to Landrover Australia tech support for answers - If I don't get any I was wondering if I should send the same things off to Bruce Davis. Or is there anyone in Tas actually doing this.

Being 200km from the car is also having its own problems. Anyone got any ideas?

I need to know what year your disco is, and is it an auto or manual.
Thanks, JC

Sorry cock, I didn't mean to cause you any embarrasment - just thought the info would help.

...........so it looks like he'll have to wait for an alternative

[incisor]

not good news, there is a few of them out there...

[Captain_Rightfoot]

Damn one went on Fleabay only a day or two for about $150 aus. :(

[spudboy]

Is there anything physically different about the Davis ECUs or is it just reprogrammed with the original bits still there?

Justin

Have you got a NNN50020 or NNN000120 sitting there?

We should be able to test his vehicle if you do.

And... I can get the original sorted for a good price.

I have a spare Defender ECU here if need be (older MSB version)


P.s> French ECU is repaired and due here Monday.
Please PM me with your delivery address.

There is a DII ecu on ebay at the moment.

Hope this may help.

Hi Brett,
get them to try the Turbo Valve, its a little elec switch that can fail and will only show a fault but not what it is. I had this problem with my TD5 Disco and Harry at MR Auto found it by a process of elimination cost $62. for the part + Labour half hour to fix.
Hope it is something simple like that
Cheers

Lads,

I have an update.

PLR may have been on the money.

It seems poor and inconsistent voltage may have been the cause. The crankshaft sensor was getting the right info back to the ecu to say the thing was atually cranking over antherfore no putting fule where it should be.

At this stage I have to thank the dealer in Launceston who have investigated this non stop and eventually were given the lead where the problem may be from Landrover Aus.

It was a new one on them as they had never seen it before.

It seems my years of beach work had badly corroded the main termnal wire to the starter motor and the starter motor itself was in the same shape. As a result the sensor was getting the right voltag and therefore playing havoc with the ECU.

This bit of info may be handing for others facing th same prob.

Short cut is I'm picking up the car tomorrow with new wound starter motor plus cables as well as new wiring looms to replace the original.

Yes a few dollars but at least she's going.

Thanks for the Help.

Justin - I've asked for a written report from Buckby's which you may be interested in for future work.

Great news Brett, Thanks in advance for the report, should be helpful for diagnosis in the future!
As said, beach work and corrosive environments play havoc with electrics; especially since the starters and alternators are poorly sealed and low down on the Td5 engine!
Good to hear it is going again.

do you think your problem might be connected to this: http://www.carelect.demon.co.uk/rrdisco2.html

seems the same sort of thing.

Are you saying the starter motor was the cause ?
If so, LR actually released a bulletin a few years ago relating to this issue.
