Found the manual, easy enough to find which is quote surprising.
So puzzled now it appears the MFU is bringing in the relay as i can feel it switching.
But why, unsure why as i see one side of the coil is 12v permenant supply other side is via a NPN & MFU.
So whats putting this on initially?
Lots to think about, weekend job to get head round it.
The part the MFU plays is the intermittent wiper delay timing but only when that function is switched on. Plus theres few other things like the headlamp washer operation sequence and interior lighting delay.

The wipers on my 200tdi disco have stopped parking and working on intermittent. I'm thinking its the park switch.
Does anyone know if the park switch is replaceable separately or do I need a new motor assembly. I think the 200tdi motor is different to a 300tdi because all the ones i've seen online are for 94-99. Might be the same as a RRC?
Any help appreciated
At the motor check u 12v supply that will be a black/ green wire. The brown/light green is from the wiper relay, black wire of course is earth.

The park switch is within the wiper motor housing, so if your motor has a detachable cover remove the screws and look inside.

Its not impossible for the wiper switch position to be faulty with the contact stuck in a made position, so further investigation with a multi meter is required.
Below is a diagram taking from LRs electrical workshop manual for the D1, which is available on-line.

The first time I started my V8s engine after fitting the Janspeed system the idle speed went at 2000rpm for around two minutes the dropped down to the usual around 750rpm thanks to the ECM doing the adjustment.
The system is still fitted and is definitely fit & forget.

They can easily contribute to an engine misfire, such as misinformation to the management system on the air fuel ratio as an example.

Hello everybody.
I'm driving a discovery 2 V8 ans I have a lot of problems.
Now when I'm driving around 1500/2000 rpm,suddenly the engine rpm drop to 1000 and then come back to normal.
Or I feel like a "push" or shocks when I'm driving
Also it has less power and one time i heard a bang i think it was coming from the exhaust.
I've put new spark plugs but I still have those problems.
I don't know if I have to look at the ignition or the injector.
Please if someone can help me
Tks everybody
As the engine has full electronic management system and even linked to the auto gear box if fitted, the needs to be plug into a diagnostic test kit to give u an idea of what is what. Iffy o2 sensor are notorious for issues, the same as the other sensors for that matter.

Why not remove the sealing strip, shown as no.3, clean and u may find the area of leak and reseal, then refit a new sealing strip if necessary.
Strip: LR part number MXC8199 strip facia to windscreen sealing. Is LRs description.
1994-5 it all changed to the 300 series with the MA 081991

I had a contractor at work that had a newish D1 200tdi so it was a few years a go, he had an issue with the light being permanent on, even after following the various procedures and advice giving, but soon after we heard he has crashed the disco on a roundabout which put him in hospital.
We didn’t see him much after that, I still wonder if it was the locked diff locked or just his speed or both going around the roundabout as he did say he had trouble getting round but really didn’t know.Perhaps thats why LR state see your dealer as soon as poss if the diff lock light doesn’t extinguish.
-
This is what is stated in my D 1 owners handbook, it seem simples enough, as ive has never had to use diff lock in my 33 years of LR ownership.

Just add the switch and of course system programming is required.

Welcome to the forum.Engine stalling can be a result of a very dirty/blocked crankcase breather (flame trap), so remove and clean by soaking in petrol also check and clean, if required, the pipe to the plenum chamber.

Errr not quite mate!
To start with the EDC (Electronic Diesel Control) by the nature of it's name does involve electronics. This is more to do with the engine but is tied into the gearbox. This was only on Auto's from 1995 onwards.
Secondly you say the Auto's are a bit sluggish. Where did you get that from???
The 300tdi Auto's with EDC have more power than the manual ones and I can tell you they are much nippier than a standard 300tdi. You got it the wrong way round! Performance is noticably better with the Auto!!
Admitidly the old 300tdi Auto's before the EDC may have been sluggish but I wouldn't know as I've never been in one.
1. Theres no electrical link from the edc system to the auto gearbox
2. Brand new D1 diesels on a test drive so I purchased a petrol engine disco.
3. The 1996MY diesel D1 was given an engine power increase (edc) to compensate for the loss through the auto gearbox, due to poor performance feedback from owners of the 1995MY autos...
So Tdi manual 91mph auto 90mph, also similar with acceleration 0.3 seconds faster 0-60 for the Tdi auto, therefore manual and edc auto D1 are very similar in performance. Both in my opinion are sluggish.

I'm re-posting this as my earlier topic title gave no lead as to my question!
I've spotted grease nipples on the U/Js & Prop Shafts on my vehicle.
Is greasing these items a regular maintenance job?
And, if so, what be the frequency of carrying it out and what grease should be used, please?
Depends of the vehicle, off-roading mud and floods frequently. Street use ones a year which I do only takes 5/10 mins.

OK Welcome to the forum.
The air con kit behind the dashboard is identical for both Petrol or Diesel vehicles.
The V8 has a valve to cut off the coolant to the heater matrix when a/c turned down to cold, the diesel doesn’t thats the only difference.
I’ve never looked at a D1 without a/c so hopefully the number of dash vents is the same, (for the early RR it wasn’t) you will require the a/c dash switches, that about it, wiring diagrams and relays are available, most of the install will be mechanical
Years ago, early 90s, the LROi magazine converted a RR by transferring parts from a scrap RR standing along side, it took a week with two guys on the job.They later suggested that an aftermarket a/c install is the way to go, something was available back then.
Anyway the best of luck removal of the dash, it looks challenging from what ive seen on the www.

Welcome to the forum. Not much salt in Israel, you would be very hard pushed to find a D1 over here with wheel arches that haven't been welded in that good of a condition regards Stephen
Not that hard when u have a 1997 D1 thats never required welding sitting in your drive. 😀

Something similar to this product https://www.frost.co.uk/brushable-seam-sealer/

I am not sure it has one but the braking logic is of mind-blowing complexity. In the old days you pressed the pedal and the brakes actuated. Not any more..
I have the workshop manual but it is not that helpful and the IIDtool indicates no errors.If all else fails I will go to LR but would prefer not too since they are pretty incompetent here.
I will try bleeding first and go from there
Why not also replace all the fluid at the same time.

Hi I have same problem with my disco 1 3.9 v8i manual it will stall after a few minutes from starting doesn't matter if it is hot or cold and won't restart just turn over with out firing disconnect the battery for a few mins and will start five times out of ten will run allday then with no issues or will play up cutting out frustrating and dangerous if on the motorway and cuts out any ideas gents no engine check light and no codes in the ecu
Not all 3.9s have one but that’s a symptom of an iffy ‘spider’ immobilise. I put up with it for six months, even wouldn’t start when disembarking from a cross channel ferry, the a few minutes it started and was ok for the rest the day, until later another day the engine cut out in the third lane at 70ish.
Time to fix, one of the spiders functions is to cut the 12v supply to the coil, so I installed a single wire from the ignition switched supply where it enters the fuse board, then following the existing loom across the engine, protected of course, to the coil top. So its just an ‘overlay’ to the existing wire so no need to go anywhere near the spider.
Also a blocked crankcase breather can stall the engine. -
Something like this that i found taped to the coil on an engine bay clean up.
I have two at the coil one for the efi the other is associated with a manual gearbox which i dont have.

Hi and WELCOME to the Forum
Its not unknown and has been posted a few times in forums that when the gearbox is cold in winter the gearbox is sluggish to change up after D is selected, usually a fluid change clears the issues. Iv never had any issues with my gearbox selection so may not be that common, mines had the fluid changed a couple of times in its life so may or not helped.
Being unable to detect the gearbox selection is an good sign as it’s difficult to detect, if you can its usually a sign of wear, of course u know its dropping a ratio or two in kick-down.
Take the disco for a gearbox road test before and after the fluid change following the procedures below where possible. For more info download LRs disco workshop manual.

Firstly, find out what is stopping the engine, lack of fuel or ignition.
A blocked crankcase breather can stall the engine, a similar symptom to yours, so remove the flame trap and hose to the plenum clean in petrol and refit, or better still replace the flame trap and hose if necessary.A flat battery will give the chattering relay sound “multiple electrical ticking noise” when trying to crank.
Get yourself a Haynes workshop manual, I expect all u need will be in there, it helped me out in my 10 years of owning a RR3.5. Still have the manual far more info in it, than the manual for my D1.

Hi, you don’t say which door but parts catalogues have drawings such as below. The 200 locks are no different to the 300 series or the early RR.

There a diagnostic test that’s available to check the items that it’s associated with.
