I feel like I know the answer to this already from other threads but I need to ask the question.

I bought a rear view mirror AH32-17E678-AB. From a range rover sport. Pretty sure this is the issue but bear with me.

Plugged it into my 2012 tdv8 and changed the ccf on the iid and the menu comes up on the dasg. Turned it on and the warning light comes on with the ignition when the normal lights are on auto. And then stays on for about 10 seconds. And then comes on when the car is in reverse?

Does anyone know if the warning light is on when its active of only when the high beams are "auto" activated?

I read that I need to get one from an L322 for it to work but I know the car recognises the sensor as when I unplug it I get a "U0242-00 (2F) Lost communication with the headlamp control module B" error and the menu disappears off the dash, and no errors when its plugged in. Just doesn't work.

Yes you have the wrong mirror sir... Needs to be from a 322 NOT a Spert!

Ok will have to spend the extra haha. Weird that the car does recognise it as what it is though

Yes but they will have very different can-bus signals so, hence why the car see’s something but cannot communicate with it…

Ah ok that makes sense.

Bought one from an l322 from america and it works! Actually really impressed with it. Reacts faster than i can.

Part number/engineering number for the one that works is AM42-17E678-BD for anyone looking

I keep looking on and off for one for my car.

There’s an American one on eBay with the HomeLink option on it but the frequencies for the HomeLink will be wrong  2002 4.6 Vogue SE - Alveston Red with Lightstone Leather
2012 Range Rover 5.0 SC Autobiography in Indus Silver with Jet/Ivory Interior
2012 Range Rover 4.4 TDV8 Autobiography in Baltic Blue with Sand Interior

That’s very strange that one from the US works! They don’t usually so, if anyone reads this thread please make sure of what your buying/ordering please… 👍

Oh I was lucky then. I took the number from this thread though and he said about getting it from america too https://www.fullfatrr.com/forum/post608671.html
