Thanks for your response Trevor.

Nice one for coming back with the info, that will save the next person a lot of time. That failure is really common on the 20 series Alphard Vellfire the little plastic tabs on the bezel fatigue and the whole switch pack ends up dropping inside the door even though the switches still work fine. Amayama is usually the safest bet because Toyota list that surround by spec rather than a simple colour choice, so entering your frame number and picking the correct trim level is the right way to avoid ending up with the black one. If you are fitting the new surround, worth checking the switch pack itself hasnt got any cracked mounting ears, and when you refit the door card make sure the harness isnt tugging on the switch pack as that seems to speed up the tab breakage. Let us know if the new trim sorted it properly and stayed put after a few days of use. Cheers, Dave

Oh blimey, sounds like a bit of a mission getting to that air con unit! It's always the way, isn't it? The part you need is usually tucked away somewhere that requires half the car to be dismantled. Hopefully, those diagrams Jeza’s found are a good help. Sometimes seeing where the wires go can give you a better clue about where the actual component is hiding. Let us know how you get on with it, and if you manage to find it! Good luck!

Hi I have a 2012 2.4 Vellfire on standard suspension. Looking to get a trolley jack and axle stands to do some general maintenance etc Was looking at 2.5-3 ton low profile jacks, would a 500mm max saddle height be enough clearance or the 535+mm required? Any recommendation for products appreciated, within a DIY budget 😂 Cheers!

Yep cleared the old codes. It’s the same fault appearing when it does appear. The rear sensor is on the list next if it starts to become a bigger problem again. Having just spent 1200 quid on new tyres, the sensor, mot, service and tax though and with insurance due in a few weeks I’ll wait a bit :)

There is a second fuel/air ratio sensor in the exhaust, maybe that needs some tlc or replacement? Otherwise it sounds like some good progress. Have you cleared the old codes, waited for the issue to appear and re-read for new codes?
