As you are in Stirling, if you are potentially looking to do a bit of preventative maintenance on the hybrid system then look up Hybrid Battery Repair of Glasgow. They can do the thermal paste replacement on the IGBTs, amongst other hybrid related work. I haven't used them personally, but they seem to get good reviews.

ATH10 does have a 4WD light, but it purpose is to indicate a fault, as you state. The hybrid display on the stereo head unit shows the rear motor in use, but there is nothing similar on the ATH20.

The rear motor is just a normal part of the hybrid drive. Every time you accelerate, the rear motor will be used to get as much hybrid assistance as possible. If it wasn't working you would be getting warning lights on the dash.

There are no left hand drive headlamps, but luckily the lights don't lift up on the left. They have a flat beam and only light straight ahead at the same height. How you would explain that to the Swiss authorities I, do not know.

1. Across the car running under the front seats. 2. The cooling fan is under the front passenger seat. 3. 12V battery is in the rear of the centre console.

Yes, they are under the air filter housing

I checked the manual the other day. It uses the camera and the head unit. There are no sensors anywhere for the lane assist.

It uses the cameras, but I think if you have removed the original stereo it won't work anymore.

From looking at the part catalogue, it appears to be hidden in the dash attached to the heater unit.

I haven't got any specific advice, but I have heard good things about using a vacuum pump to remove all the air from the coolant system first, and then coolant is admitted. With no air to get trapped there should be no need to bleed it. This is a kit I found on eBay, but I have no personal experience of using one LINK

I bought this one. Works well, is easy to put on and take off, and packs down small for storing. https://amzn.eu/d/0aowWRXb

Unless I've missed it, you haven't mentioned the Webasto heater. An expensive, and useful, add-on.

Google Duvalay. Probably does exactly what you want, but they are expensive.

That is extremely cheap Karen. I'm sure you will get a quick sale, but it would be worth you looking around at the prices other campers are being sold for as I am sure you could easily put it up for twice that amount.

Put the chassis number into this website and it will tell you if it has been done. It probably has, but it shows up in the Car X report regardless. https://www.toyota.co.jp/recall-search/dc/en/search

Is a cheap OBD port dash mount speedo acceptable for an IVA test?

As you are in Scotland, Hybrid Battery Repair based out of Glasgow seem to get reviews from Alphard hybrid owners. https://hybridbatteryrepair.co.uk/ One of the most common faults is the hybrid coolant pump failing. If the lights aren't on when started from cold and then they come on after a short drive, this could be an indicator of a coolant issue. An easy way to check is to take the cap off the hybrid coolant radiator (the pressure cap on the right hand side when standing in front of the car) and you should be able to see the coolant level bobbing about with the engine running. If not the electric coolant pump has likely failed. Don't take the cap off when warmed up unless you like hot steam on your skin 🥴

That looks like someone has tapped into those circuits by trimming the edge off the fuse and soldering the wires on. Slightly dodgy and if the fuse blows it isn't a straight swap. Can't help you with what circuit is what unfortunately.

I'm guessing you want to keep the interior warm and limit cold engine starts? If you leave it idling it will stop and start the engine anyway as the hybrid battery charge cycles up and down, so fuel consumption will be minimal and it will stay nice and warm.

The maximum weight for your Alphard will be shown on the registration document as revenue weight. It comes from the information on the export certificate. For my 2003 hybrid it is 2435kg. I seem to recall from what I have read it is something like 400-500kg on top of the unloaded weight. The gen 1 hybrid has highest maximum weight of the gen 1models, but it also has the highest base vehicle weight

You need to find out what is draining your batteries. If it is just parked up with the fridge turned off, the leisure battery should not be getting drained in a week. Even then, it shouldn't drain the main 12V battery as well.

Presumably you have a camper conversion? To really know if the tyres are underrated you need to know the weight of the vehicle now, and when fully loaded. In an ideal world you wouldn't be taking the vehicle over it's stated maximum weight, but life isn't always ideal. 40psi isn't ridiculous for a camper conversion. When stopped in traffic I tend to put the gearbox in park, and apply the handbrake if on a slope. I don't like holding the weight of the car on the gearbox pawl so I use the handbrake, but plenty of people don't bother. I also don't like unnecessarily blinding the driver behind me with my brake lights. Using park rather than neutral has an advantage in my hybrid, but either or would be fine in a non hybrid.

The Nationwide cover is the same for breakdown. It covers the person, not the vehicle, and there are no restrictions on the vehicle that an Alphard driver need be concerned about.

A Nationwide Flex plus account for £18 a month gives full personal European AA breakdown with no age (or import) restriction on the vehice being used. It also gives Aviva travel insurance and there is gadget insurance as well.

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