You will now have to reset the windows so you can operate them from the drivers' door switches. Go to each door and lower the window halfway down then take it all the way up and hold the switch for 2seconds

You may have to click on a save button in the menu, failing that try a new camera

The chrome trim is held in place by the light clusters plus trim clips. You have to remove the trim panel inside the door, you then have access to the nuts that hold the lights on, once they are off the chrome trim is easy to get off. The original reversing camera is 6volt so you will need to get a converter unit, available on eBay, plus you will have to locate the correct wire at the head unit loom to trigger it. When I fitted my Pioneer AVEC unit, I found the easiest way was to fit a wifi transmitter unit in the tailgate connected to a new 12v camera, both powered from the reversing lights, then the wifi receiver unit in the centre console below the head unit. e.g. wifi transmitter/receiver unit https://www.ebay.co.uk/itm/187285465898

Put 38psi in all round, google the 4psi rule, follow the instructions and adjust accordingly

By the look of it, that retro fitted switch is not quite the right one for a series 10, see link for correct one plus it shows what wire does what https://www.ebay.co.uk/itm/165029893993

It could be that someone has spliced into the wiring, maybe for the rear fog switch, and the warning light is getting feedback. Check if the light goes brighter if you switch the front fogs on

I can confirm what Gamith has said, the toll card reader can be unplugged and removed, the power to it can be used for usb points if required, front fogs (and warning light) are controlled by the rotary switch on the lighting stalk

Kathryn, you did not say if it's just the blade or the arm as well, both are available on eBay e.g. > https://www.ebay.co.uk/itm/197316927881 for future reference part numbers can be found in https://www.amayama.com/en/genuine-catalogs/toyota/alphard

There are 2 types of clips, the ones at the top push into holes on the trim then slide down onto a retainer on the door, the ones at the bottom fit into square slots on the trim then push into holes in the door. Both types are available on eBay; Top clips number 196877085828. Bottom clips number 384266009852. I have seen posts where people have used Sikaflex adhesive to hold the trims on

Some of the prices people have been charged are daylight robbery. When mine had to be changed I got Febi bushes (TAB-226) off eBay and my local garage quoted for 3 hours labour, £225 + vat, unfortunately for them, it took 5 hours due to how rusted in they were, but they honoured the quote. Ideally, the tool set makes removing and refitting the bushes easier, the set is available on eBay, but I read that someone did it on their drive by burning the bushes out and using a homemade tool to press the new bushes back in. There is a set method for the final tightening of the bolts and if it is not followed it puts the bushes under stress so they are likely to fail quicker than normal

See link for part numbers, then you can check online e.g. eBay, Autodoc, etc https://www.amayama.com/en/genuine-catalogs/epc/toyota-japan/alphard/MNH10W/152282/engine/1904

you could just change the solenoid contacts rather than the whole unit

In case you have not researched the fault code: DTC P0793, found in many Toyota vehicles, indicates a problem with the Intermediate Shaft Speed Sensor A circuit. This sensor measures the rotational speed of the intermediate shaft in the transmission and sends this data to the transmission control module (TCM) to help with gear selection. A P0793 code means the sensor is either not sending a signal, or the signal it's sending is not being recognized by the TCM. Symptoms: You might experience a check engine light, transmission issues (e.g., rough shifting, difficulty engaging gears), or increased fuel consumption. Importance: The intermediate shaft speed sensor plays a crucial role in controlling the transmission, and a faulty signal can lead to transmission damage or improper performance. If it was mine I would not be driving long distances.

2.4L have a timing chain, it just needs regular oil changes

Unfortunately some insurance companies are just complete jobs worths, the reason they won't insure imports is because of expensive or lack of body panels. Admiral are reasonably priced, then there is Adrian Flux or Mark Richards Insurance, the latter specialise in imports. What you need to do if you are going to stay with your insurance company is phone them and tell them that your vehicle is an Alphard and that there is no such vehicle as an eight seater Avensis, you need the paper work to show that it is an Alphard because then the company will not have a way out of not settling any claims
