Appreciate your help man! Do you know if anyone has a td5 d2 nanocom for sale on any of those places you mentioned? Probably still be cheaper than a new one from England at this point and I'll need it for my air suspension regardless

Already done more work to this truck than my last two utes.... Let the fun begin

Not at the moment but I look often. They don’t come from England, they come from Cyprus. Colin from BBS is a member on here but we don’t see him much now. D2 and P38 cars are getting on now. You might get lucky I sold mine when the car was off the road for some time. Regretted it and had to get another one when my Disco became my daily driver again.

What do the temperature and fuel gauge do with the ignition turned on? It's there a red light on in the temp gauge?

If you pump the throttle pedal 5 or 6 times, the fuel pump should go into a purge cycle and run for quite some time whilst cycling on and off occasionally.

If you can't hear this, report back.

I will need to go plug it all back in, I was going to just try a new ECU as i found 2 for $50 each off a guy online. From memory the temp gauge sits at halfway and the fuel gauge was on full with a red light on one of them

Check the ECU fuse, I think it's in the fusebox under the steering wheel from memory.

Checked it, all looks fine... Will try a new ECU and contact cleaner on everything tomorrow and see if it fixes anything...

Shack will know more about this than I do, but I think the ECU will have to match the old one, and will need to be programmed. But, I’ve never done it myself so I don’t know for sure.

Yes, you will need some way of re learning the security code. Otherwise the new ECU will show as immobilised.

It's quite possible the original ECU has died with the dash lights you are seeing.

It's also quite possible that there is a power problem somewhere as well.

I'd definitely be choosing that first.

It's really hard without any diag gear.

I saw one on marketplace for $880!!! the chap is in Ballarat. Read through description etc, and it looks like they are a reseller, kind'a sort'a ... they have products and services, but they don't have any products, nor any services available!

Not sure if scam, or new website for new business, or what.

You might get lucky, I have seen them, but these days people like us who hang on to their Discos hang on to their Nanocoms as well. Tf you bite the new bullet you'll get it pretty quickly, and some of the prices people ask are nearly the same as new anyway. We used to be able to get a group discount on here, but I think the demand is falling. I kicked myself when I realised what I had lost, and the one I sold was also unlocked for some other things. That goes with the device, and you need to pay again if you want that functionality. The D2 TD5 kit does work with some of the functions on a TD5 Defender, but not the other way round. I was able to help someone with their ABS, for example.

Anyway....

Oh, and don't be tempted by some of the others out there that claim to work with Land Rovers. Sure, they can do some things, but it's important to understand that the TD5, while it has a OBDII style plug, it is NOT OBDII compliant. NAS cars probably were, because the US mandated it some time before the ROW. And they were mostly V8, in the Disco at any rate. You might find a Bearmach Hawkeye I guess. They did most of what you need, but they have been out of production for years.
