Hello, I have a A4, B7 2008, 140HP (left side steering), sline, 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 (as the modules was from a UK car). All was OK except the back doors where not locking anymore. With the old one they close and open without an 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 ?) 3. Does this part need to be 1:1 with the old one ? (have in mind that I can do the VCDS coding) Thanks!
