Hi I have problem with mirror in bmw g02 x4
Left and right side has  heating and dirve assistance triangle in glass 
left had also dimming function no camera only folding 5 pin 3lin bus 2 mirror blinker
Problem is that mirror was damaged in accident but I think it's only housing glass and mounting has no visible damage now after assembly I had error message that's is error in left mirror electronic driver assistance triangle but ista test is ok blinking light 2 stages are ok like in right side.
When I switched Glass side by side error stay in left side. So I think it's not glass issue but Lin bus electronic.
New mirror assembly cost 800 Eur only electronic is not available in dealer it is possible to buy used g series g30 or g10 g05 mirror and replace Lin electronic or even from f series because it's more on market and cost about 100e I see number of pin is the same, I now that I need solder right pin housing but is ok

I tried switching Lin bus electronic from UK mirror because in this car only driver side has dimming function. No luck electronic in left and right mirrors had different numbers and no working

You cant do that. The left/right identity is in the electronics

Now I am now that, but can I use from f30 ? Or with top view and I see that camera had 4 pins hsd cable I think and standard 2 pin for blinker and 3 Lin is this correct ? 9 pin mirror dimming Lane change warning with top view is cheaper than 5 pin dimming and Lane change warning

I use electronic from left mirror from g01 with top view but I change housing to non top view mirror. now it's working

Meaning there's no way to have both side mirrors to have autochromic aka auto dimming?
