At least I think that's what the nano said. Right hand blend motor on a friends 38 btw, forced it with nano and the percentages don't alter but fine testing the left hand blend at all percentages. We can hear the motor working though on both. Removing it and testing the motor with a 9v battery and all is good, no gears stripped either.
The board looks good too and as the nano doesn't give a potometer fault I'm assuming that is good. The cable going to the multiplug on the back of the hvac looks perfect too. He does have a spare set of unknown motors complete off a scrapper which we will fit later today(just the one, cut, solder, shrink wrap). Hopefully that will fix it and get the book off unless there is something we have overlooked! We are both a bit green on 38s but learning slowly lol!
Just had a Disco with Thor engine here, modified for off road use and the owner says he's won a few competitions with it. LPG converted (Prins) and was running slightly better on LPG than on petrol but on either fuel it was idling rough (as though it had a big cam in it), though the owner said he'd rebuilt the engine and it only has a standard cam. The two OBD error codes pointed to both front lambda sensors failed and lambda readings for both banks were full lean but I found when I blipped the throttle the lambda readings momentarily went rich as they should, which pointed to maybe the the lambda sensors (at least signal) showing actual mixture so the mixture actually lean. It was looking as though 2 failed lambda sensor heaters were causing the rough idle but when I unplugged the MAF and restarted the engine it ran perfectly, correct mixture on both banks and lambda readings flicking like they should.. It runs a lot better with the MAF unplugged but I warned the owner it might refuse to start, or start then refuse to run, or if it runs OK at light engine loads it might still not run OK under heavier loads. I asked him if the ECU had been modified, he said not. He's going to fit a new MAF, see how it runs with that fitted and maybe new lambda probes if it runs better with the new MAF but codes pointing to lambda's still reoccur.
Any other thoughts on it running better with the Maf unplugged?
As usual when I see a Disco / Rangerover I pointed the owner to this forum
The other day my RR failed its MOT due to one of the rear pads (left outer) being worn down to 1.5mm...all the others were 7/8mm. I completely re-did the rear brakes, changed the discs, replaced the pads, and cleaned the whole lot up. The only other thing i found is that one of the right hand carrier guide pins was fairly well seized... So what do we think happened? does all the pressure go to the LH rear because the circuit senses that the RH is seized. Why would only one pad - the LH outer be worn so badly, while the LH inner ie piston side was hardly worn at all ?
Quick question - are any of the aftermarket suspension height sensors 'any good'? Recommendations?
Does anyone fancy a go at this? It seems that for the price of fitting a new driver's door handle you could have another P38 for £1
(plus the cost of fixing all the other bits they're not telling you about lol)
Got a new one on the '99
Last night, I went for a drive and within about 30 seconds of setting out, with lights on, I got 3 messages:
RH Tail Bulb out, LH Tail Bulb out, License plate lamp bulb out.
Upon inspection, all 3 lights were merrily shining away. Shut off and upon re starting, got the same thing.
I have checked RAVE thinking it was possibly an earth issue. Found that they do not share a common Earth point, so non starter there.
Any clues as to where I look from here?
Hi guys,
Well, I've dropped in a few times over the last while to find answers to various things, but otherwise not been around for a while.
On the big plus side, the RR is still just trucking on. It's been more-or-less my daily driver for the last couple of years and just keeps on doing its thing. I know I'm asking for trouble in saying that....
Just passed it's MOT last week with 2 or 3 advisories - one of which was the exhaust having a mild leak. I also know that my front CATs are knackered (but at least they're quietly knackered, and not making that horrible tin-can noise any longer..) I've also grown too tired of the howling and roaring caused by the previous owner's centre silencer delete.
So it's new exhaust time, or at very least the front pipes and centre silencer. The problem is I find various part numbers for the down pipes. My VIN is A448*** and I get WCD105350, WCD105360, WCD000860.... and I can't readily see any difference. They all seem to say they're OK for a 4.0L V8 with CATs.
Can anyone point me in the right direction please? If there are any pitfalls/obstacles to doing this job I'd also appreciate a 'heads up' - I've seen some references to a gearbox cross member?
Any help and advice gratefully appreciated as always.
Ta.

Having fixed the issues on the RT side with distribution motor, I have turned my attention to the LH side distribution flap motor.
Nano shows error as "Motor short circuit to 12 volt positive"
The motor moves the flap just fine from recirc to fresh.
I have unplugged the motor and substituted in a blend motor with a good drive. Works fine. Same error.
I found the 2 wires at the HVAC head unit plug and snipped them and attached motor directly to the plug.
Same error.
I have swapped in 2 different known good, tested working head units and same error.
What am I missing? Nothing in that circuit is shorted to positive anywhere???!
Well, it's not so much an "Issue" as a real boneheaded maneuver.
I was replacing the diversion blend motor on the RH side of my LH drive '99. went well, and no more checkbook.
Having done the heater core on my 02, I was just breezing away putting everything back together, because I knew what I was about!
Replaced glove box fascia, having smoothly clipped in the cable release cassette........Without checking to be sure it was engaged....OOPs
Put in hinge fasteners and attempted to open the glovebox. Yea, Right! Latched, and the cable is not engaged.
So, what is the approved procedure for extricating myself from this??? Non destructively preferred.
I suppose it is the same as if the cable broke at the latch??
Thanks in advance for any suggestions!
Cheers!!
Edit...An hour later......
Had something to eat (And Drink!) and had another look.
I am guessing that if I use my super shallow ratcheting screwdriver, I will be able to remove at least the screws along the top of the
piece that holds the top in. Then attempt to either re seat the cassette or jigger the release with picks?
Fortunately, the aforementioned ratchet driver is in the tool kit on boat, so my only option tonight is another G&T.....
Any refinements cheerfully welcome!
Whilst diagnosing another issue with our 2001 P38 I noticed that the water hose than runs up and over the top of the alternator belt and into top of radiator had an unusual bugle to it. It was adding about 15% to the diameter of the rest of hose. I turned engine off and slowly opened the expansion tank cap and the affected area of hose decreased to its normal size. Engine cluster temp gauge rads 12 o’clock position and an infrared temp reader shows constant temp along hose from engine to top of radiator. This section of hose appears to be full of air, however, the small hose from top of radiator shows a constant flow of water when engine is hot.
I’m assuming that this is not a normal condition but am reluctant to change a hose just for the sake of changing a hose. I followed the manual for bleeding the air when I installed this hose two years ago.
Thoughts?
Starting (pardon the pun) to get intermittent start faults with 2001 P38. After driving a few times and a quick stop of say 5 minutes, when I turn key to start I get a “click, click, click” sound and no turnover. This will happen about another 4 or 5 times during start attempts and then the vehicle will start. Has happened 3 times over past 10 start attempts.
I’m leaning on replacing the starter. Vehicle has 151,000 miles and the original starter. Ground and positive cables all look good and power is getting to starter. Difficult to replicate the issue when underneath ……
Anyone have this problem in past?
Thanks in advance
I'm aware that one of the symptoms of the broken plastic washers in a GEMS ABS modulator is a 'clicky' brake pedal. Now for years my brake pedal squeaked whenever I applied the brakes but a few years ago that stopped and was replaced with a 'clicky' feel. As the braking performance hadn't changed, I put that down to a bit of wear on the pivot between the pedal and the pushrod rather than anything more serious.
Last weekend I drove to Amsterdam and back and experienced strange behaviour. I filled up with LPG in Belgium, then drove to Calais and the first time I applied the brakes the pedal went down much further than normal but coming off the pedal and re-applying the brakes, all was back to normal. Considering I'd just driven 120 miles at a steady 70-75mph without touching the brakes at all, this suggests to me that maybe the O rings inside the modulator are starting to weep slightly. I'm never going to be able to replicate the problem in this country (driving 20 miles without touching the brakes is considered a good run), so could just leave it but I think a modulator replacement is on the cards in the near future.
would anyone know or where I could download a workshop manual for a 2010 Discovery 4 tdv6 ?
like the rave one for the p38 as always handy to have one
Removed dash, and all associated, in order to replace both blower and blend motors.
Putting it all back together and I’ll be damned but I can’t find the 2 “plates” that are used at the bottom of glovebox to secure it to the vehicle. Can’t find the screws either. Got the upper three but lower set is missing. 2 days later I thought I’d ask here if anyone has a spare set hanging around in a jam jar somewhere that they would sell?
Thanks
Hi all, just joined up as looks like I am getting my old P38 back after 7 years in another owner hands. Going to be good to be back in a P38.
What is does, and where does it need to go?!?
I didn’t unplug it intensionally😆

Is the P38 truly a luxury SUV, or does its notorious reputation for electrical issues and reliability woes overshadow its appeal? What has your experience been with this vehicle, and do you believe the charm of owning a Range Rover outweighs the potential headaches?
Big red beast passed its MoT today with an advisory about replacing a distorted CV joint gaiter on offside.
Internet search says Britpart, Allmakes, GKN and Land Rover themselves all supply gaiters. Ruling out OEM as silly expensive what breed of replacement is of decent quality and likely to last? Word on the street is that many modern gaiters are sadly short lived due to material deficiencies. I suspect mine are original so they have had a decent innings.
The buggeration factor is such that it makes sense to do both side this year. If one has gone the other is unlikely to be far behind.
Also got an advisory calling for replacement of rear brake mudshield plate. Britpart are around £80 a pop and OEM twice that, which seems expensive for a simple plate. Is this something a breaker could supply economically, bearing in mind that a used part will almost certainly need sand blasting and painting or is breaking out the welder and sheet metal stocks the only feasible method of doing an inexpensive repair.

Considering the P38's reputation for both luxury and mechanical issues, can it truly be considered the best of both worlds for off-road enthusiasts? What are the most common pitfalls owners face, and do the benefits outweigh the costs in the long run?
Is the P38 becoming the next classic to invest in, or are we simply romanticizing a vehicle known for its quirks? As prices fluctuate and enthusiasts debate its reliability, what is the real future of the P38 in the collector's market?
