Retrofit Folding Mirrors

Hi,

I have E90 320i 05 with power and memory seat but without power folding mirrors. I did some research through some topics and found that it can be retrofit with a power folding one. I just want to make sure that with my car, I really can do it without extra wiring. I don't want to waste my money buying a new pair of power folding mirror and it can't be used.

So, from my understanding, the steps should be

1.Replace the old pair with the new one

2.Replace the control switch with the one that has a little button to fold the mirror

3.Use NCSExpert to add $313 to CAS and FRM module

Do I miss any step? Should it do the trick? These are some pics of my mirror's plug, it has 3 wires and 3 pins.





Thanks in advance!

After coding the VO.

You need to do some minor coding to the FRM module aswell...
(im going to do some work on my car so ill be able to check the exact codes that needs to be changed)

But one is to enable Lin-bus. the commutation bus for the mirrors.

Then you also need to set what type of mirror you have (chromatic dim, Heating, powerfold, memory) etc..

Then you "should" but not necessary also enable the link code that makes you able to toggle them out or in with your key fob.

And since you checked that you existing wire harness is 3pin on Both driver and passenger side you should be good to go..

Can you pleeeeease tell me how to enable Lin-bus? I did all what I just wrote up there. But it doesn't work. Already added $313 to both FRM and CAS module but still can't be fold

By the way, before I hit "execute job" button, I changed job from "SG_CODIEREN" to "FA_WRITE" or I supposed to use "SG_CODIEREN"?

When coding VO codes you need to make sure that it is in FA_WRITE Thats very important. VO coding videos will show you this. Do watch a video or two before trying as it might not end that well for the module

Mirrors working yet?
