Hello,

I have a A4, B7 2008, 140HP (left side steering), front power windows only

I recently swapped my CCM as power windows where not working anymore. I coded the new one using VCDS to the specs of the car. All was OK except the back doors where not locking anymore.

With the old one they close and open without na issue.

On the car I had 8E0959433CN but I found a 8E0959433CH and used that.

1. Can someone tell me what CCM modules support back doors open/close also?
2. Are there any specific model numbers that I need to look for? (like the ending CN, CH etc - is there a place where I can find a reference on what the modules do, or CAN DO to be more exact ?)

Thanks!
