Chances are, the OEM compressor is a Denso unit, even if it uses R1234yf. I would try to locate the Denso part number, which is usually found on a sticker on the compressor itself, and look online for pricing. They're likely much cheaper than the ones that have a Lotus label attached.

It's possible there was still air in the lines. The slave cylinders are a rather solid Toyota part, but the seals can go bad on them eventually.

Assuming you found the ICM, the output from C9 to RC1 on the EMS ECU seem to pass through. No indication of what level of signal is being passed. Some ICM outputs are grounds, some are +12V. Testing it with a voltmeter should be relatively safe; with the A/C switch on, if you have your black probe on a body ground, and your red probe on C9 and no voltage is shown, then it's likely a ground output. Switching to continuity test, once the A/C switch is turned it, if it's a ground output it should beep. Conversely, if it's a +12V output, you should see that indicated on the first test, and there'd be no need to test continuity. If you want to remove the trinary switch from the equation, you can just put a jumper on the harness side pins for that connector.
One thing to note; your green box is only half-correct. It actually should encompass the "TRINARY SW COOLING FAN" beneath it, as that's all one unit (a binary pressure switch + a unary fan switch == trinary switch). There's actually 2 separate connectors for the different "sides" of the switch within the unit. Here's a picture of one I found for our cars:
Since Lotus updated the part number, it looks like they may have also updated the wiring colors from what's stated in the wiring diagrams. Might have to figure out which connector is which by pulling the front right wheel well cover.

The vehicle data sheet shows 0.745 kg of R134a, but the service notes mention recharging with 0.625 kg.

I don't see where the fuel filler flap solenoid is tied into the ICM or CDL. One side of the flap relay coil is on the battery positive, and the other side is wired to ground via the dash switch.
C9 on the ICM is an output, but I couldn't find mention of if that's high or low. You should be able to hook up a voltmeter and toggle the A/C switch and see.

Not to be a Debbie Downer, but any gas loss is indicative of a problem. Hopefully it's something easy and cheap to fix though.

I don't think there's a troubleshooting guide in the service notes, but I would check these in this order:
- Fuses (C28, R11)
- Refrigerant fill/pressures (if good, issue is likely related to electronics; if bad, likely a leak)
- If leak, refill w/ UV dye and find/fix leak(s)
- If not leak, check compressor, clutch, trinary switch
- Rinse/repeat until working again

What side do you need? I have a RHS spare.

That's how I used to get the front end up. Jack the rear on one side, put a stand with a puck under the front lift pad, set it down. Move jack to other side of car and repeat.

From the service notes. In numerical order, it should be:
1: Brown/Yellow
2: Black/Yellow
3: Black
4: Blue/Purple
5: Grey
6: Blue/Orange -
You may need the Homelink bridge for the Chamberlain/Liftmaster openers. The version of Homelink in the Evoras wasn't the most recent, so it may not be directly compatible with the security features of your opener.
See here for compatibility.

There's both the BOE CAI and the Radium CAI available for the NAs. I believe BOE ships worldwide; not sure Radium still makes their intake. Might be able to find one in the secondary market.

I've used Spraymax 2K clear before and it works great. Not just for automotive applications, but other things as well.

It's up near the pivot point of the clutch pedal. #14:

I'm not sure that's the case. It cuts the cruise control certainly but that's pretty much all it's there for.
The service notes indicate that the clutch sensor switch is also used to briefly cut fuel between shifts.
I replaced mine a few years ago when I was encountering stalling issues when slowing to a stop. Even though it wasn't throwing any clutch sensor-related codes, it seemed to clear up that issue.

Don't worry Dean, I've got you covered. Thought this would come in handy at some point in the future: https://divinehandcraft.co.uk/products/lotus-evora-logo-side-repeater-sticker-decal

I've not looked at the Toyota service bulletin, but the oil cooler hoses are flexible for a reason - they go between engine and chassis, which move relative to each other.
From what I can see on the videos, that setup is different to the Lotus, that looks like a heat exchanger setup, whereas the Lotus have an air oil cooler at the front of the vehicle. I'd double-check what you've got, with what you've ordered there...
I have never personally seen one fail on a Lotus (as yet).

Apparently later in the model years, Lotus used the all-metal oil cooler feed/return pipes. In the thread I had started on LT, Julian had posted a picture of his 12S heat exchanger housing with the metal pipes.
The oil lines that head towards the front of the car should remain flexible (#7 and #8 below), and I believe those are the ones that were covered under a Lotus recall. I believe those are also only present on S cars.

This set of rubber hoses was replaced (under TSB) on other Toyota 2GR-FE vehicles because of this very problem. Their solution was to remove all the rubber hose components and replace them with solid metal ones.
I actually bought the necessary parts to accomplish this, but never got around to doing it on mine, since the oil has to be drained first, and it's much easier to access this area from the rear seat access hole.
I've attached the Toyota TSB for reference. I had also created a thread about these potential Toyota TSBs and how applicable they would be to our 2GR-FE-driven cars: https://www.lotustalk.com/threads/2gr-fe-tsbs-and-other-part-updates.435937/
If you want to replace those rubber hoses with the solid metal ones, the part you're after is Toyota 15767-31020, which is the metal pipe and flanges, or the kit 04004-29131, which should include the 2 gaskets.

If it's the turn signal PCB itself, then you'll have to remove the headlight assembly and open it up to determine if there's an issue.
On the spare assembly I had purchased off ebay, I found the PCB power connector had come partially undone from its solder pads. It could be a similar failure in yours. If you plan on fixing it yourself, you'll probably want to drill out the rivets holding the heatsink to the PCB, and remove it. Then heat up the backside of the PCB (aluminum-backed) on a hot-plate or with a heat gun/hair drier, then try and repair the connector.

Strange coincidence that another one of these has been reported recently. I just repaired mine in Jan, and someone on the FB group is going through it now as well.
Something in the early non-Inteva latch release mechanisms bind as they age, and it results in neither of the handles working to open the door.
You can fix this yourself if you're handy, but it requires removing the 2 door striker bolts from the inside of the car. I posted a how-to over on LT:
https://www.lotustalk.com/threads/open-a-door-when-the-latch-has-failed-closed.475272
Give me a few to fix it; the mods deleted the wrong duplicate post which had all the info, and I have to recreate it in the second post.

Here's a thread over on LT that goes into depth on the window regulators. Unfortunately, they're fairly specific (electronics-wise) to our cars, even though the regulator/motor assembly can be found in various other vehicles.
The end-result is that no cross-reference parts have been found (yet), but there's the potential to make a wiring harness that would allow the regulators from Seat vehicles to work in our cars. Not sure what the progress is on that currently though.

It's rather normal I believe. Mine are like that, as are others I've seen while underneath their cars.
Not sure if there's a need for a fix. If nothing else, now our cars are even lighter.
Latest lotus spec serpentine drive belt?

Continental does have the Gatorback (now called the Elite) belts for the NA 2GR-FE, but not the S. They do offer their standard OE Multi-V belt in that size though (4071130).
From what I could find, it seems they're transitioning their Elite line back to a straight ribbed design. Not sure why, as I always thought the Veyance design was better, and one of the reasons for acquiring them.
