Which white bits? The small rack (think rack and pinion) that runs on the cog on the motor or the bit that it pivots on? I've got the rack that was on the original one but they are handed so that one is for the side to side movement (I found this out after getting one of them in place on the motor only to find the ball on the end was facing the wrong way). Not got the other bit that the thing pivots on as that was missing on the original mirror so I pinched the one off the spare.

No, I bought the car from a Range Rover specialist who by all accounts is pretty good (RRLondon). The owner bought it in to them and asked if they were interested in buying it as he'd been quoted a huge amount for sorting out the stuff for the MoT. They weren't interested in buying but offered to sell it on his behalf.

Incidentally, I must have had it idling for well over an hour last night while trying to get the running on LPG sorted. Plugged the Nano in to find a coolant temperature of 68 degrees. Definitely need to change the stat but I'll leave that until I get a mixer and replumb the vaporiser. No point in draining and refilling it twice.

B&Q will do you a cheap gas blowlamp which will be enough. I've found that if you slide the clamps right off the end you can get a thin cold chisel in the slots to open them up a bit too. If you use something like Stillsons on the adjuster, they bite harder the more grunt you put on them and don't round off the hex like a spanner will. First time I did mine I ended up laying underneath it, handing onto the chassis and pushing a pair of Stillsons with my feet. It moved eventually.

Yes, I had a spare mirror anyway but it was a non-memory one so only had 6 wires and not 8 like the memory one has. Got the little plastic rack out of that one and a white plastic piece that the mirror carrier pivots on and it all works now. Fiddly to do and as the teeth on the motors were a bit chewed it doesn't move completely smoothly but it moves and now points in the right direction. Took almost as long to get the glue from the duct tape the previous owner had used to hold the glass somewhere close to where it needed to be as it did to fix the mechanism.

You might need to reload the software from scratch so the dll files are installed, otherwise try copying them from the XP machine to the Win2000 and see if that works. Do you have an Alesei N or the earlier Alesei? They use different software and aren't compatible.

When you say it doesn't change on the button press, do you mean that ordinarily you switch to petrol before turning the engine off and leave it there until up to temperature? Why not leave it switched to gas so it switches when ready? The two main problems that stop a system from switching are a problem with the temperature sensor so the system thinks it isn't hot enough or a lack of gas pressure. If the temperature sensor has become disconnected so is open circuit, it will report -40 degrees so won't allow it to switch. If it beeps as it would when you run out of gas, then one of your solenoids could have died so the gas isn't getting through. Having a look around for anything disconnected and checking the solenoid coils would be a good place to start.

would appreciate some help. Have P38 Gems here on the mountain in Spain - LPG stopped working - just doesn't change on the button press - waits then beeps to make me press back to petrol. Have finally got the ECU lead from UK and downloaded Zavoli Alesei N software which loads and seems to work on my Win XP desktop (not connected to car) but does not run on my old laptop on Win 2000 . Says various dll files missing. Do you know if it should run or is Win XP the earliest ?

Might have been better to start a new topic rather than resurrecting one from a year ago. I'll start a new one for you and reply there.

There's receipts in the folder for work done on the LPG system and for the price the whole system could have been replaced at least 3 times. The venturi on the OMVL mixer is a plastic insert so could have been blown out by one of the big backfires that has split the airbox into 3 pieces but someone has obviously thrown it away not realising what it was or what it was doing in the intake trunking. But it came from London, enough said. While there are cowboys everywhere there seems to be nothing but in London. Having looked through the previous MoTs, it's been tested at the same place for the last 4 years and each time has failed on a number of things that seem unlikely. I suspect they were just failing it, telling the owner it was going to cost X hundred to put it right, he just paid it and they issued a pass.

Mine is the complete opposite, all the guys that work there are into cars (although there is one young guy who runs out the back as soon as he sees me approaching as he doesn't understand anything older than about 2000). They will have boxes of things like assorted copper washers, bleed nipples, grease nipples, nuts, screws, bolts, trim clips, body fixings, you name it, they've got it and you can buy one at a time. They are quite used to me walking in and asking for bits for 1960's cars, where even if they had a registration number (as most are imports that haven't yet been registered), it wouldn't help. If they don't have it in stock, they will get it for me tomorrow and it really is tomorrow too.

Continued last night. Fitted the new (Britpart) tailgate straps that the postman delivered (and I'm sorry Sloth, but they lined up perfectly and the bearings moved smoothly too), refitted the offside rear door trim (the little plastic pegs were in the door but not attached to the door card), got the passenger side door mirror working and the glass attached by it's clips and not held approximately in place with a bit of duct tape and decided to have a look at the LPG system. That has also been the subject of untold bodgery.

For those not familiar with a single point, a little explanation. You have a mixer, a venturi with lots of holes around the inside edge, attached to the throttle body. That is fed with gas at just below atmospheric pressure from the vaporiser via a stepper motor controlled valve to fine tune the mixture. The stepper is driven by a controller which takes a signal from one of the lambda sensors and causes the stepper to open if the mixture is too lean and close if it is too rich. The airflow through the venturi in the mixer draws the gas in so the more air being sucked in by the engine the more gas gets sucked in with it so the stepper is just there to fine tune.

All this lot was buried beneath the air intake trunking so not exactly easy to get to or see and a lot of the cabling had been bundled up and taped looking like it had been done fairly recently and the vaporiser is all new and shiny too (an OMVL R90E, rated for engines up to 6 litres or 380bhp, identical to the one fitted to my car). Pulled the trunking off to look for the stepper only to find there wasn't one there, it had been replaced with a manual valve that would normally be used on an open loop system on a carbed engine. The cable that should have gone to the stepper was in the recently taped bundle of wires. The software for these systems will show the lambda sensor output so you can see if it is rich, lean or happily flipping between the two as it should and it also shows how far open the stepper is so you can see if it is nicely in the middle of it's travel or at either end. Started to tune the vaporiser output pressure and got it so it was idling on gas with the manual valve in the mid position. Swapped the valve for a stepper and started to twiddle. Got it idling on gas with the lambda switching and the stepper moving nicely around the mid point. However, the adjusters on the vaporiser seemed wrong. There's two, one that deals with the actual output pressure and a second idle bleed screw that dribbles a constant supply through. This latter one is normally screwed fully home as it is only needed on a very low revving engine that doesn't generate enough suck to draw any gas through at idle and the adjustment on it is very fine, 1/4 of a turn makes a hell of a difference. That was partly open but the output screw was almost all the way out meaning maximum pressure. As soon as I opened the throttle, the lambda showed fully lean, the stepper went fully open and it still showed so lean it didn't really want to rev. At that point I gave up and decided it was time for food and a bit of head scratching.

Thought about it more and this morning went out to check my theory. My theory was that if the venturi was clogged, then the gas wasn't being sucked in, it was having to be forced in. So, off with the intake trunking again and looked and immediately could see the problem. The bloody venturi is missing from the mixer! Instead of a smaller opening with holes around the inside edge, there's just a hole with a pipe for the gas to come in. No wonder it won't rev, there's no way the airflow can suck any gas in through this......

Look like I need to get a new mixer too......

I'll have more of a play with it tomorrow and try various different combinations. I've got 3 different 4 digit numbers and two of those are allegedly the EKA (one in the service book and one written on the owners handbook) so with a bit of luck I'll be able to sort it with the Nano if it does all go tits up.

Mine cracked in exactly the same place.......

Any idea who did the original install? Usually the only time anyone says they don't like LPG is when the system doesn't work properly so they assume all LPG converted cars don't run right. I've had people comment about mine and ask how I put up with all the hassle and they don't believe me when I tell them it never gives any hassle, runs just as well, if not better, on gas than petrol and costs me less to run than a diesel. No brainer in my opinion and if it were my car I'd tell Guy Salmon where to stuff it (not that I'd be seen dead taking a car to a main dealers anyway).

I've emailed Marty to see if he is aware of this one and it may only apply to older cars, but I discovered something last night which I figured was worth adding to this thread. The BeCM in the Ascot says EKA disabled but I wasn't sure what effect this would have. The central locking currently doesn't work on the drivers door (so I've got to pull the latch and deal with that) but that means that I can lock it with the fob and the drivers door stays unlocked. Last night I'd locked it on the fob and then without thinking, opened the drivers door. The hazards started to flash showing that I'd triggered the alarm (sounder is unplugged) and my initial thought was, Oh sh*t, which one of the handwritten numbers on the paperwork is the EKA. Unlocked it with the fob and the hazards continued to flash. Put the key in the ignition, turned it on, dash said Alarm Triggered, RH Door, hazards stopped flashing but when I turned the key the engine started. No immobilisation, no press remote, no enter EKA, no nothing, it just worked and the engine started.

So, if EKA Disabled does remove the need for the EKA, it would seem to be the answer to an awful lot of grief suffered by numerous people.

Yes, saw that, it's free postage so cheaper and Furness have a good reputation but their's doesn't include the rubber mounts or bolts which I need.

Is this http://www.ebay.co.uk/itm/Range-Rover-P38-sunroof-motor-entstoert-/172734392420 all I need or is there anything else missing?

Seat bases can be swapped if you remove the actual cushion from the rest of the metalwork. I recently fitted a passenger side cushion to the drivers seat on my white one as the original was in a similar state. It means taking the seat out and stripping it down but simple enough to do, I even managed to find out why my heated seats weren't working while it was in bits and now they do.

They are so disgusting I'm tempted to use my mod status and delete the post.

But then I would have to change my name to RRToadhall.......

Seems the original part number was AMR3376, which then superseded to AMR6406 which was also superseded to AMR6477 so there were obviously a few improvements made to the design so you'd be better off going for the later number. There's one here http://www.ebay.co.uk/itm/AMR6477-FUSE-BOX-RELAY-FUSEBOX-RANGE-ROVER-P38-2-5-DIESEL-/162570054632 which is the correct one, comes with all the fuses and relays and free postage. From the look of the fuses (and the later part number) it looks like it was a replacement fitted not that long ago.

Got the rotary coupler half out and then decided to check RAVE. Found that the cables don't plug into it but are part of it. Checked continuity between the plug on the SRS cable under the dash and the connector for the airbag itself. All OK so reconnected with a squirt of contact cleaner in both plugs. Turned on the ignition and the dash said Airbag Fault, checked the fault with the Nano, cleared it, Airbag Fault on the dash disappeared and the SRS light went out. Success! The only thing on the MoT failure sheet that I haven't checked (because I'd forgotten about it) is the rusty ferrules on the brake hoses but I have a sneaking suspicion they will be as rusty as the ball joint boots are split.

Now I'm on to the more cosmetic side of things. So, the seat has definitely seen better days

I've sorted one or two minor things that were annoying me and then thought I would turn my attention to the sunroof. Along with the other error messages I was getting was one that every so often would pop up and tell me that the sunroof wasn't set. Poking the button did nothing so, having watched Marty do it on Smiler's car at Summer Camp, armed with my big screwdriver, I pulled out the interior light ready to start twiddling the manual adjuster. My theory was, judging by the mildew around it, that it hadn't been used for some time and the motor had just got stuck. First thing I noticed when I pulled the light out was a dangling socket so I figured it had been disconnected for some reason so had a look for something to plug it into. I think I have found the reason why the sunroof doesn't work......

The motor appears to have gone the same way as the viscous coupling and fan.

So it doesn't keep nagging me to set the sunroof I've gone into the BeCM settings and told it there isn't one, that should shut it up for the time being.

Edited to add that imgur does indeed work. Time to download all my pictures from Photobucket and close my account.
