Hi yeah i just found that out ….. my central locking fob wont work and the garage was hoping to re program a new one using the obd ??…….. the central locking has a imobilisor attached , so i’m told so engine wont turn over
Be easy to find wires and delete them. You only need a live to pump and a live to starter solenoid and you're away

Hmm, i would think that's an aftermarket device, nothing to program as such.
1. sounds like you need to change your garage.
2. give more details as to what you have.
3. then help will happen

At that time computers were still relatively in their infancy, laptops had not been invented!
"The IBM PCD (PC Division) later released the IBM portable in 1984, its first portable computer that weighed 30-pounds. Later in 1986, IBM PCD announced its first laptop computer, the PC Convertible, weighing 12-pounds. Finally, in 1994, IBM introduced the IBM ThinkPad 775CD, the first notebook with an integrated CD-ROM."
Reminds me of the story of the AA man called out to help an MGB owner in trouble. The owner allowed him to spend 15 minutes looking for a spot to plug his diagnostic in!!!!!
Before pointing out the car was made in 1963!

Well that opens the tin of worms doesnt it
.Sorry I cannot help anymore as dont know the TD5 and as a conversion it could be a mix.
How do "they" the garage think its the immobilizer?
Can you work on it because they could spend hundreds of your hard earned beer tokens to find the problem.

Maybe one of the new owners swopped over the whole loom, from a later vehicle including all the problematic electronix. You can try using RAVE or summat to help you look for all the sensors and other sh!t that would come from one, RF, immobiliser etc etc.
Best of luck with your worms!!!

That would be setting alarm bells ringing for me.
A 1984 vehicle isn't a Defender. It is a Land Rover Ninety. And an early-ish one at that. As standard that would have a 4 cylinder petrol or diesel engine, or a very few had V8s. As has been said, no electronics at all on the engine, No ECUs, nothing powered at all on the vehicle, all manual, I don't think it would have had wind up windows, but sliding Series type.
And the amount of work needed to do that conversion is enormous, virtually everything would have to be replaced for Td5 compatible components, and I think the chassis would have to be modified to take the engine and gearbox.
I would be wondering of it is in fact a complete Td5 Defender which has somehow acquired the identity of a 1984 Ninety.
Some clear pictures of the vehicle would be helpful in clearing some of this up.

This makes a lot of sense.
Ouch!
looks like a ringer.
I'd be looking for signs the VIN number has been replaced/ tampered with, on the chassis or wherever it is stamped in/on.

I wasn't making an accusation, it could be a legitimate conversion.This makes a lot of sense.

But the work required would be enormous. Another change would be the fuel tank, and it's associated chassis mounts.
A Ninety has a tank under the seat, and a mechanical lift pump mounted on the engine.
A Td5 Defender 90 has a rear mounted tank, with an electric fuel pump inside it.
I was really just trying to help the chap. If he doesn't know what vehicle he has got, or what parts of what vehicles he has got, it is going to give him trouble every time something goes wrong, or he needs to order parts.

Well I'd still look for this first, then, if as you say there has been an enormous transplant we would be able to move on with helping him out.
Just wondering why anyone would do this, rather than simply changing the engine and driveline.
According to this 1984 was a critical year and yes they did have wind up windows etc.

So maybe the changes weren't quite as radical as all that.
Put it this way, it must all have worked at least for a while so, as usual, nothing is unmendable!

The windows are trivial. Different doors, and a bit of extra wiring will give you electric windows.
But the different engine, gearbox, associated mounts, fuel tank, mounting the several ECUs is quite a lot of work and expense.
I would be interested to see a picture of the vehicle from the rear. A Ninety chassis and a Td5 Defender chassis are visibly different.

As you say, it'll be interesting and I'm sure we'll be able to help him.

Hi here is some photos … the original army guy built it up from the chassis over a number of years while in service , vin/engine numbers (TD5 turbo diesel )etc all match i knew it was a 90 and i mistakenly called it a defender in prev message……i’ve been using it as my everyday car but its now stuck outside my house so taxi to work tomorrow ?
…. i can only think to call a auto electrical guy in to hopefully bypass the immobilisor ??

That has been built as a Td5 Defender 90, on a brand new Td5 galvanised chassis. I doubt if there are any Ninety parts on it except the numbers and the registration document.Hi here is some photos … the original army guy built it up from the chassis over a number of years while in service , vin/engine numbers (TD5 turbo diesel )etc all match i knew it was a 90 and i mistakenly called it a defender in prev message……i’ve been using it as my everyday car but its now stuck outside my house so taxi to work tomorrow ?
Which from your point of view makes life easy, you can treat it as a Td5 Defender 90 and ignore the rest.
