You might change your mind when you see the price of a throttle pot. That said, I have a vague recollection of seeing a more reasonable replacement based on a put together adaptation of a different pot and mounting. Anyway, whatever. As for the butterfly - yes, absolutely. Take off the plenum...

Vacuum test is quite easy. First get yourself a vacuum gauge. You'll need to attach the gauge to the plenum, I pull the vac pipe for the heater on my RRC, not sure if there is a suitable vac port on a D1 but would think there may be a blanked off port you could use. Do not use the vac line to...

Sounds intriguing. I suspect there is something simple not playing the game. If it passed MOT emissions the engine is fundamentally sound. The cat test does two measurements, idle and fast idle although there is no load. Maybe a little obscure but at this time of year depending on...

Apart from the air suspension ECU and combined memory seat and mirrors ECU all you really need is a multi-meter. AFAIK there is no "diagnostics" for seat ecu; the internal battery leaks and destroys the board and some of the pins on a couple of the chips. Unfortunately the board has two layers...

1990 makes more sense. It can be a minefield. Mine is an HA Vogue SE on a '91 J plate but that was a change over year so some bits are 1990MY, for example, the swivels, other bits are 1991 on. Good luck with it, the ABS can be, well, errrmmmm, challenging. Once it is working fine and no warning...

Clearly there is an ABS fault. Your first move has to be getting the blink codes from the ecu. Once you know why the red light is on you can then troubleshoot the system. If pulling to the right, check all the calipers (front and back) are working correctly. Sticking pistons are a common...

RRC and ABS oh joy!! The brakes are relatively good generally but the rear calipers are prone to seizing. Disco 1 has a similar issue. Don't be fooled by the lack of action and/or fluid. The RRC ABS system has two parts, the hydrostatic system and the combined power and hydrostatic system. To...

Sooooo, you've replaced the hydraulic booster unit. Simple enough. There is only 1 pipe connected to the accumulator, this is not likely to have anything to do with no rear brakes. Now, as it happens the braking system is two in one. you have a HYDROSTATIC CIRCUIT and a POWER CIRCUIT. The POWER...

Hi Jai, nice to see you're still about. Me, I'm doing better. Walking is still painful; it's a bit like having two sprained ankles, especially first thing in the morning. Apart form that not too bad. Just completed some repairs on the Rangie. The back axle was weeping where the diff pan rotted...

Mmmmmmmmmmmmm........ Whitwell. Jai, don't we know somebody who got stuck there once?

I have owned my '91 RRC for almost 15 years. I have used it for green laning and it has been abused but it still keeps going. Rot repairs should be expected for any RRC. If you can find a reasonably straight one that has been looked after then go for it. However, if you are not able to do...

My Rangie is having surgery (again!). The rear diff pan has finally rotted through and more chemical metal is not the answer so I thought I'd just pop the rear axle off, get a diff pan - weld it on and put it all back - simple, a few nuts and bolts, a couple of wires and brake pipes how hard can...

Slow down! As said glittery stuff is a stop leak potion of some sort. Check the radiator core isn't blocked - do not attempt to clean the core with a pressure washer, you can destroy it that way. Viscous fan tool???? what's wrong with either 1.1/4 or 32mm spanner - works for me? Don't forget...

OK, I did find what I had in mind. https://www.rswsolutions.com/index.php/discovery-i-abs-codes/267-discovery-i-abs-blink-code-procedure Note this relates to the D1. The system is slightly different but it has broadly similar characteristics and is also a WABCO system. Most of the codes are...

OK, let's see if we can work through this. I don't have a reference for an ABS error 2-3. You say it is constant? Have you actually cleared ALL the error codes. The ECU stores multiple errors and sometimes it can take a while to clear them all down. I assume you found the diagnostic plug and...

FWIW maybe have a quick blast through this: https://www.v8forum.co.uk/forum/viewtopic.php?t=8569 I saw another thread on LR4x4 that might be useful. Will post a link if I can find it.

What coil are you running? A "performance" coil could be a problem. Big coil will burn out the ignition amp that's why you should stick to standard amp and coil. There is no advantage from a "big" coil. Also, on timing yes the V8 will run at 12 degrees advance; I set mine at 12 degrees running...

You didn't say you let it run dry. Sounds like you have a bucket of air in the system. I understand what Discool is saying but I'm not sure if it is essential; time and much brake fluid should enable you to bleed the system through although I am not aware of a DIY method for activating...
