That sounds like glow plugs and/or injectors.
Here is an interesting link to that kind of problem on a 2006 220D:

No, it is not the same.

Part number for Room Temperature Sensor - INCAR:
88625-50120
PS:
If you need the SOLAR sensor at a later time, you can get a cheaper one. That sensor was also produced for FIAT, Jaguar and Alfa Romeo - part number: 077450-0911 (look for it on ebay).

Looks like that is a temp sensor and light sensor in one.:

Auto-dimming feature was standard on MK3 models. MK3's and MK4's wing-mirrors have the same shape.
Some years ago I put an MK4 mirror-glass in an MK3 wing-mirror housing.
Only difference I can see is, MK4 models came with blind spot feature for the n/s mirror-glass.

The thought had crossed my mind but nothing on UK eBay at the moment.
And if you just send an email and ask them directly? Maybe you get lucky....;o)

Yes, that key-fob part number (89742-50640) is for the European model - see links below, but if I was you I would try to find a used one first by checking out car-breakers in the UK (via fleabay maybe?) and reprogram it to the car. I have reprogrammed a used one once. Keep in mind lots of LSs end up in East Europe

LS400 1996 and 1997
Cheapest way and decent quality is to get a key and chip from China via Aliexpress. Was about 14 bucks in 2014.
The China key was cut by a local key smith and the China transponder chip was programmed by the local Lexus dealer.
I was able to get the fob programmed with the "key/remove key/pat your head/rub your tummy dances" programming procedure, but not the key.
(Key Fob – 433MHz - 89742-50640 (LS400 8/95 – 7/97))
(Immobilizer Box – ECU – 89780-50010 (8/95-7/97))
Master Key - TOY 40 – long blade (89785-30020 (LS400 8/95 – 7/97))
PS:

For years I used Vredestein Wintrac Extreme very happily on my LS400. These have been superseded by the Vredestein Quatrac Pro. They are all season but with snow and mud markings and the tread looks similar to the Wintrac Extreme (those were snow tyres). Anyway I just bought a set(4) of the Quatrac Pro tyres for just under £500( for 245/45 /18 as I now have an LS430, so the right size for the LS400 should be cheaper). I would highly recommend the Wintrac Extreme tyres and hope the new ones will be good but as I am only starting to use them....
Please keep us updated on the performance of the Quatrac Pro tyres on your LS430.
TIA

Quatrac 5s seem to be a good trade off between performance (ie grip, not Nurburgring malarky) and price.
Anyone any experience of these?
Quatrac 5s have asymmetrical tread pattern with good traction and handling, but pretty noisy. Especially when driving with open windows.
I am okay with the Quatrac 5s, I like it a little louder.
This article confirms my experience. https://motorandwheels.com/are-vredestein-tires-quiet-noisy/
If you prefer the LS-quietness, do not buy them.
I would love to know how the Quatrac Pro (looks like it has a quieter tread pattern) and the Michelin Cross Climate (symmetrical tread pattern) on a 95-97 LS400 perform.
PS: The LS400 came with asymmetrical tread pattern.

LS400 1990 - 1994
Plugs torque: 18Nm
LS400 2000
Plugs torque: 17.5Nm
No mentioning of any sort of grease when reinstalling spark plugs.
PS:
- Remove spark plugs on an alloy engine only when engine is cooled down.
- Do not use anti-seize on spark plugs. Put them dry back in.

Known problem with cars in combination with an automatic transmission.
What's to stop it happening again?
How about avoiding dead stops and heat spots by pressing and releasing the brake a few times?
Always leave some meters for creeping forward on a traffic light.

Far better quality. Toyota original equipment (OE) bushings have some sort of reinforcement fabric in them, and after market ones not.
Bushings from Febi and Beck & Arnley will crack prematurely.
For example, Febest makes good ones for the Lexus Rx450h

Those center caps are discontinued. I went with Renault center caps. Same measurements.

A couple of (the hottest) months (on record) and no, it was a private sale.
Having looked at it in daylight, there's the front sensor which is probably fine but if I can get it out to clean and test it, I will. The rear, which is in the corner of the left hand speaker (correct me if I'm wrong) has the sensor cap wedged right between the glass and the parcel shelf so something's definitely afoot there. Annoying because it's probably a nightmare to get to - any advice on how to get to it gratefully received!
Do I need to be looking at the room temperature sensor as well? There are some conflicting opinions in this thread and whilst I can see the "Solar sensors have nothing to do with AC" logic, my research into other threads regarding air con and the fault codes I have make me come to the conclusion that the solar sensor does have something to do with it.
Edit: just read your post John and that makes a lot more sense.
I ought to add, that I've checked all the fuses and they are all ok and that the revs change when the AC is on so that's good too.
If you wanna change the thermistor cooler sensor (88625-47031) in the rear, you do it like this. See pic 2. That sensor looks like the one I replaced on a 1997 LS400.

Yes, it was an option on the MK3 model in 1995 - at least in Germany.

I wrote an instruction some years ago. Good luck.
Before you measure any rest current your car has to get into "sleep mode". Keep in mind that in order for the car
to sleep at all it must be off and nothing can be "touched" (no opening of the trunk or doors, no pressing any buttons
on the key fob etc.) If something is touched the timer starts all over again. How long it takes for it "to go to sleep"
I am not quite sure, but 30 minutes should be enough and rest current should be under 0,05Amps (50mA). For comparison
my 1997 LS400 has a rest current of 24,8mA. Alarm went off at about 11,82Volts.
Battery should be charged when less than 12,4Volts (75%).Procedure of how I did it and got a reading of 24,8mA:
- Turn ignition off and pull the key
- Open engine bonnet and close its lock with a screwdriver
- Close all doors
- leave the Battery connected and arm the anti theft deterrent system either by key or by key fob.....and check
security lamp if it works- to be sure leave the car alone for about 30 - 60 minutes (I went back to the car after about one hour)
- go back to the car's Battery and measure rest current without interrupting the current.
Before disconnecting the Battery put the pair of test leads (black one/-)to the negative Battery terminal and
the other (red one/+/amps or mA) to the negative terminal clamp.......now disconnect carefully terminal and clamp.PS: I put a Varta E23 (70ah 630a) in. That was 5 years ago and without any problems since.

Don't you rotate tires? Lexus recommends tire rotation at approx. 7500 miles on a 96 model.

Part of the pipe is flexible and my car's cracked right there due to the vibrations, temperature and age, I would think.
In a UK LS400 it is right in front of the driver and can cause dizziness due to carbon monoxide poisoning when inlet air turned on.

Those 9 spoke wheels won't fit the front axle of a 95-00 LS400 because of the 50 offset the have.
Original 1997 LS400 = 16"x7" (5x114.3, 60.1mm hub) / ET40 offset
You will need those 10 spoke wheels:

Would shifting in S mode be of any help in that kind of situation? That way overdrive mode is turned off (engine brake is being used) and the car is able to stabilize better I would think.
Battery drain?

Regarding Battery drain - should be under 50mA - on a 97 model its 24.8mA:

I am not quite sure, but 30 minutes should be enough and rest current should be under 0,05Amps (50mA). For comparison
20 minutes after arming the anti theft deterrent system my 1997 LS400 has a rest current of 18 - 28mA.
(before 20min it is about 40-50mA).
Alarm went off at about 11,82Volts.
