Certainly a few clues of an HG failure being mentioned 🤔

Its definitely not a vent it cap, so has been modified, looks like its a 20mm hole so per have they intended fitting a sensor. The vent to stop a vacuum will be either a 5mm hole on the side or the cap is manufactured to include a vent...

I assume the tailgate was functioning 100% before. So whoever did the work in replacing the tailgate would have left some pencil marks to aid realignment when fitting the replacement, something similar to bonnet and side doors removal and...

Have you read the Handbook ?

As already mentioned you will find the info in the owners handbook. Whit most modern cars theres two handbook, basic and the full on version which u have to download from LR via their app. Then look for the chapter ‘driving modes. Not a disco I...

I should have mentioned - it is a discovery sport. I didn't see a separate forum...

SOLD. Sold it after 26.5 years of ownership, it was just a replacement for my rusty 10 year old car RR, I didn’t need the disco after the first 2 year, the job I had for it landscape my new garden was now finished, but kept the disco as it as it...

Not normal D2 V8 UK spec engine then. Here in the U K we have a D2 with a Thor 3947 engine, which is so call by Land Rover a 4.0 litre D2, a different engine to D1 but the same CC as a D1 V8, which is called a 3.9. So where in the World are you?

I’m If you have grease in the steering swivels the you will have Teflon coated swivel balls, if the balls are chrome then they will have fill and drain plugs plus early swivels also had a level plug as fitted to my old RR 1987 so the oil could...

Now corrected😊

I think you mean "do NOT" but yes that sounds sound!

My quick search gives me a LR part number as STC778 Kit headlamp cover so possibly nothing to do with adjustment, anyway unfortunately they are obsolete.

Wading plugs are only fitted on vehicles going into water that having a timing belt and/or a clutch, autos and/or a timing chain don’t need them.

I have explained what is dim-dip and how it functions already.

🤔 my 1987 RR wasn’t equipped with dim-dip nether was my TVR in 1985.

Yes, a resistor which is mounted at the rear of engine bay, just unplug it to remove the dim-dip function.

🤔 Pink relay ? No such thing fitted to a D1 and the only item that dips the headlights with the side lights on is the lighting switch. With D1s dim-dip feature, when the side lamps are switch on the headlight dip beam is then on but in a dim...

It works again now so we will pretend it never happened

No. So unless there is a timer unit somewhere set at 10 minutes 🤔 then I would suspect an iffy light switch or intermittent wiring connection.

As aways now, expect questions on issues with the D1 & 2 have already been asked on LR forums https://www.landyzone.co.uk/land-rover/discovery-2-tailgate-lock.127980/

Just pop into the the main dealer and pickup a free accessory catalog for the DS, or as we can nowadays just Google 😊 https://accessories.landrover.com/gb/en/discovery-sport/carrying-towing/carrying/vplcr0137-roof-rails-silver-finish-panoramic-roof/

Other faults with the fob that will give issues is, iffy button micro switch's which can be replaced, if your careful, and battery terminals at their joint with the PCB

I've just found my second key and this one has enabled me to open and close the vehicle remotely! I'm a bit ashamed because I should have thought of that first. So my problem is really with the key and not with anything else. I'd like to say a...

The Wanner gun has an air release valve, so no issues there. 😊

I purchased mine back in 1966 when I purchased an MG which had grease nipples on the steering. Still have it for my disco now fitted with a flexi spout to make things easygoing around both props.

I'm almost certain that here is no MAP sensor on this system. The ECU uses a full range throttle potentiometer to determine a load signal. You will need to check for flash codes. The 14CUX ECU was a primitave unit so if you have an engine light...

Your central locking operation is simple to the D1 as much the driver’s door lock is called a master the others are called slaves so when the drivers door locks or unlocks the others follow, its a long while ago but the D2 forum was full with...

The good news the mechanism appears ok, but the standard procedure as stated in the owners handbook is when locking with the key in the driver’s door lock you must always unlock via the fob otherwise the alarm will activate, and that isn’t ? ☹️

Best to decide if it’s mechanical or electrical. Mechanical issues were known with either the locking or unlocking motor, both are housed within the drivers door lock, the issue was resolved. When locking or unlocking do u hear any sounds. For...

The retaining screw is to ground the receiver against possible electromagnetic interference, the item’s functional earth is within the loom, possibly a black wire.
