There are few things, if any, worse than intermittent faults to try to track down. It's usually something dirt cheap to fix, like a bad connection of some sort, but finding it can take so much valuable time up that I've often wished something expensive had gone kaput for certain. Time=money.

Oh, I fully agree; not a suitable environment for ****ers. But do please remember I do this kind of thing for a living. Almost all the tests I carried out were very light-touch and couldn't possibly have damaged the ECU. The loading an oscilloscope places on a circuit is feather-light (30pF || 1Mohm) and the crank sensor emulation procedure was precisely the voltage level the ECU would be expecting and I delivered it via a 600ohm source impedance, so no danger of burning anything out there either. And yes, I took the customary anti-static precautions. Do give me SOME credit FFS!!!;)
If I can persuade the bloke to return me the old ECU I'll open it up and check those caps you or Shifty mentioned, btw. If it's one of those that's gone I'm sure to have an equivalent 'in stock' so can fix it; get some money back by re-selling it on fleabay.:)

Was not saying you are a muppet but just trying to explain things to others that may not be as clued up on electronics. A little knowledge can be a dangerous thing and unfortunately youtube seems to be full of armchair experts encouraging people to carry out some very dubious practices in the pursuit of saving money. It will be interesting to see what you find wrong with the old ECU. Keep us informed.
 
I don't expect to find anything obviously wrong with the old ECU and don't plan to waste very much more time with this issue. It stopped being fun when I ran up against the roadblock of the coding problem. I'll test those capacitors and visually inspect for anything which looks like it might have burned-out, but that'll be the extent of it. The dustbin will be beckoning invitingly!;)
 
Would have been so much easier to have bought a Hawkeye or Nanocom in the first place, they lose little value on the secondhand market and the problem could have been diagnosed in a few minutes :rolleyes:

Anyway, despite the above I'm pleased the OP has the problem resolved ;)

So ... are you driving the fender yet or not?

Sadly not. It was supposed to be ready on Wednesday but the new ECU hasn't turned up in the post yet, they've told me. Monday on this island was a bank holiday so that didn't help matters much. This is something you just have to get used to living out here in the middle of the Irish sea. Patience is a virtue I don't possess in infinite quantities. :(

+1 with Shifty.

IMO, ECU,s dont just fail.

Have a browse on Disco3 site, some epic "faults" all caused by "mechanical" electrical problems, crushed wires, dirty connectors etc.

Ive been putting a paper together, for a work related project, on best practice for maintenance of electrical equipment, lots of really meaty stuff from US Navy/Air Force on how to fault find problems, rectify and prevent electrical problems. The US navy ones are good, try keeping a modern jet air worthy, when daily its getting drenched in salt water!

It really isnt rocket science and it doesnt cost a fortune. Believe it or not, cotton buds and tooth brushes feature a lot in their official guide notes!

Ill post up some links if anyones interested.

I suppose this thread did remind everyone what a bunch of muppets LR dealers are though, so I guess something good came of it!

I learnt a long time ago that even the most reliable things can and do fail, I currently have 4 dead Storm ecu's on the shelf that may or may not get fixed,they don't have the best reputation in the world of ecu repairs...
 
I finally got the 'ender back today. Final bill for the new ECU was 233 quid inc VAT and fitting which was a pleasant surprise. Shame the first thing I did when I got it home was to lock myself out of it, though! :mad:

That was a bargain especially if they supplied the replacement ECU.

Yes they did and yes it was!
This guy also told me that when the actual ECU itself blows, there's no diagnostics out there that will tell you. It's the one failure they're unable to identify, it seems.
 
Hi all,

Pleased to hear that you finally got everything sorted Landlover99. Sadly I am late to this thread but having read it from beginning to end I just had to comment. I bought my TD5 110 in November with 134000 on the clock, all was running well until the week before Christmas when on 2 occasions it just stopped running, luckily after I had parked up!

A few days later that was it, would not start but nothing obvious wrong. Got the local garage to have a look and they were convinced that it was fuel starvation and so they went down that route. Fuel pump and pipes (snapped when removing old pump!) replaced and still no joy. They then started looking for other culprits but luckily I think they ran out if interest so towed back home.

Once I had it back outside the house I decided to use the free cover provided by my bank to get a hopefully more professional idea, luckily the chap from the AA who provided the cover had previously worked at the local main stealer. Even before he put the diagnostics on he said it would be the ECU, which sure enough it was.

Long story short, not only did I need a new ECU, but I have also ended up forking out for a new fuel pump and pipe work, injector loom and various other bits and bobs, also had to hire a car over the Xmas and new year period and didn't get the Deffy back until mid Jan!

If I had owned a Nanocom at the time I would have found this out straight away and would have been back in the road for Xmas eve.

Best advice I would give a new TD5 owner would be to buy, or make friends with an owner of a Nanocom.

Cheers

Andy

My Nanocom has paid for itself several times over.
