Wiper arm pullers are available quite cheaply if it does become difficult to remove. Link

Only the OEM stereo will give you the hybrid info sadly

The information is all contained within that thread showing what I used, but it is attached with sikaflex 522 adhesive. It's going nowhere, even if I wanted to remove it.

Even if they make a mistake, so long as you notice promptly they can go straight on to the MOT database and change it to KM. It isn't the end of the world, and doesn't create a dodgy looking MOT history.

The Consumer Rights Act 2015 trumps any supposed 3 month warranty. Everything about the vehicle should be of satisfactory quality, as described, fit for purpose, and last a reasonable length of time. If the engine blows up in six months time you can still expect a free of charge repair on a £12k vehicle that you have taken reasonable care of. Just Japanese are a reputable dealer, so are unlikely to disappear in a puff of smoke at the first sign of any problems.

The rear heating is unaffected by the state of the pollen filters. The rear has it's own fan, heat exchanger, and aircon coolant supply. It just recirculates air it pulls in directly from the inside of the car. Only the front fan draws in air from the exterior. Are you sure the fan in the rear is running? Is it a camper conversion?

I put a plastic C rail into the passenger side roof gutter and stuck it in with sikaflex adhesive. Had the drive away awning attached in some pretty horrific weather and that C rail never budged.

The only suggestion I can offer is to connect up with Techstream and read the codes. It could be absolutely anything.

If the 4WD, VSC, and hybrid warning light (car with exclamation mark) are lit the most likely cause is a hybrid fault, not a VSC fault. If they come on after a period of driving a common issue is the inverter coolant pump isn't pumping and the inverter is overheating. Whatever the issue, you need Techstream to find out what the codes are and to get live data.

You really need to get some live data out of this car with Techstream, or you are just throwing good money after bad.

You will probably have to remove the front passenger seat. The service plug is located under the rear right hand corner of the passenger seat. If you go to the 4 minute point of this video it shows the plug https://www.facebook.com/share/v/17XWgWV9dx/

A common failure point, but fairly easy and cheap to rectify. This post should help

WD40 is not the best choice for spraying on sensitive electrics. It leaves behind an oily residue that just ends attracting dirt. Electrical contact cleaner is the better choice as it washes away any contamination and totally evaporates afterwards. Get some, and use it to remove the WD40 from those connectors before you end up with more problems. However, even contact cleaner is unlikely to be the silver bullet you need. If the ECU has been having a regular bath but is now perfectly dry and intermittently working it is likely that it has suffered internal damage, possibly some corrosion. If you are feeling adventurous you could remove it and open it up. There might be visually obvious problems, there might not. It would be worth spraying it with contact cleaner whilst it is open, and you might get lucky and it was just some surface contamination or lingering damp causing an issue. Ultimately you either need to find someone willing and able to check for and repair the fault, or put a replacement ECU on and hope for the best. If you are prepared to travel, Kaspars Krumins in Wigan seems to get nothing but positive reviews for his work repairing Toyota hybrids, and he carries spares for Alphards.

If you are concerned that the rubber seal around the sunroof isn't sealing then don't be. The seal on the sunroof isn't designed to be water tight, hence the drain hoses. If there is a large visible gap then there could be an issue.
