Opps and so it is. 😉☺️ Been a long day. My disco has two identical resistors which were taped to the coil but only one is used. There was a post on it years ago so i went out and had a look and found both, apparently there was an issue (may have been engine not running) and the exact resistor...

Ok the 3.9 ECU also has a connection to to the coils neg terminal via an in-line resistor. Attached is a copy of the 3.5 hot wire diagram. All i can find at the moment.

Although I had a RR 3.5 flapper I didn’t know much about it as I didn’t have any issues and LR service it, but in my quest for knowledge I do have a Haynes Manual for the 3.5 RR I’ll have a look see first at the relevant wiring diagram. With my 3.9 Disco there’s a 12v supply from the ignition...

The reason possibly is when a winch is fitted the airflow would be restricted. Theres was a post a year or so from a owner of an auto whom was concerned about air flow so was looking for suggestions on rising the auto box oil cooler thats behind the grill higher, no mention of the AC condenser...

You may or not be lucky, some times a superseded part number can mean just the part now has a different means of attachment. I expect it would be difficult to find what the differences were if any, even with the aid of Google.

No, if its a Range Rover the 3.5 was “flapper” the 3.9 “hot wire”. For a D1, all EFIs were hot wire. but the 3.5 air flow sensor had a different part number to the 3.9 and then there was two part number changes to follow the last one being mid 1995. So for the D1 possibly not.🤔

The solenoid clicks and it has its own issues with its contacts, if u can hear it in side the car, if your still using the original item. So from ignition switch to the relay I forget at the moment where it was but there was a relay under the bonnet that I removed some times for vehicle a...

I assume the click u hear is the starter relay so check that the relay has switched voltage to the starter solenoid, is the solenoid engaging to switch voltage to the starter ? and so crank the engine. 13.3v seems ok following a full charge it will settle to around12.8v … depending on how...

DIY if you have the skill and the diy tools to do it as Ive done in the past… not on a Land Rover. But for precision, the kit that some garages now have to check the steering i’d go there.

Definitely you won’t find it on a 3.5 V8, it doesn’t have one manual or automatic.

My disco runs just ‘north’ over the central line, as your gauge also runs just over the central line, being west as its a horizontal display 😊 If it stays that way like mine its not an issue.

Looks similar to the dash that my 1987 3.5 so an EFI other than mine was MPH. As you have a 300 Tdi engine fitted so you require a coolant temp sensor part no. AMR1425 indicated by a green band. Thermostat if interested is ERR2391. The range rover dash illuminated indicators are self explanatory.

Hi to you. I’ve never heard of re-programming a D1 remote fob, but after disconnecting and re-connecting the vehicles battery the fob has to be re-synchronised to the security ECU, simply done by pressing the lock button on the fob around 4 times the central locking will then lock. So assuming...

Ok, look for as they may have added by a previous owner of the vehicle the blue bag that was fitted at the rear of the centre console and the roller blind covering the boot. Both were added a year or so latter from the 1990MY disco and are now collectors items, sometimes found on eBay.

Ok GA 1990 and so one of the first then, 3 door models were on sale around September 1989 with the 1990 model year, with the 200tdi or 3.5 with carbs. non electric windows, steel wheels plus the blue upholstery. It was rumoured that the 3.5 carb V8 was surplus RR stock. Definitely a dealer fit...

Bull bars for the D1 like the previous RR slotted through the under bumper spoiler to bolt onto the leading edge of the chassis. Then for the D1 there’s the A bar and made of … shall we say made of plastic and foam, which appears to me a lot lighter and a bit thinner but even that is only an...

The ignition warning light and rev counter are two different circuits, turning the switch to position 2 the lamp should illuminate and the spinning alternator turns it off, the alternator supplies a pulse signal for the rev counter, now its possible that you have a faulty alternator, the new...

Well 1990 V8 thats a classic if it’s one of the first EFI D1. What ever the age of D1s they just have a standard key that can be copied at most shoe repair shops. As the vehicle has central locking with a remote fob but the alarm wasn’t a standard when it left the factory, and option fitted by...

Don’t expect a reply, the OP hasn’t been seen since Aug 2017. I’ll have to look out for that book 😊

Yes there is an easy fix. Stated in the workshop manual the is idle speed is 673 to 728 rpm at normal running temp. The idle adjustment is on the throttle side, you may find a anti tamper plug fitted. Perhaps check at the mixture the same time You may find a Haynes Workshop manual handy as it’s...
