Hi,

I managed to smash my MMI screen in my 2017 Audi A4 190PS black edition B8 model. Audi quoted me £1300 for the job which I think is too
much.

I ordered another screen off ebay but I didn’t realise It was a different part number. The screen that came out of the car is “8W2919604” and the one I ordered is “8W2919605” (it came out of a 17 plate Audi A4 TFSI). The new screen has a different connection at the back, it’s blue in colour and has different locations for the locating tabs.
I swapped the motherboard out of the old screen and put it in the new screen and hooked it up. Everything works but the screen is blank. I then shaved a tab off the connection in the car, put the new motherboard with the new screen and hooked it up. Same thing happens, everything works but the screen is blank.
I’ve tried a soft reset etc and I’ve checked the fuses and all are okay. The reset did nothing and the screen is still blank.
I’ve called a few places and they reckon that the screen needs coded to the car.
I am not sure because I had the old motherboard in and the new screen, surely the car would recognise the original
motherboard?

Does anyone one have any experience with this matter or can anyone tell me if this is in fact true, that the screen needs coded to the car?

Thanks,

Liam.
