Hi everyone! My first post on this forum. I have been reading this forum for a while and it's amazing. I have found a lot of information for doing several retrofits and other stuff. Thanks for that. But now I have a problem. I was doing ch/lh -lights and footwell lights retrofit (thanks to RobinA3 for looms and lights) and when I had all installed it was vag com time. But I had a problem with vag com coding. My central electric byte 0 looks like in the picture below. As you can see there is only those two options. No options for footwell lights or ch/lh-lights. After doing some research on this forum I found a thread where was different central electric modules listed. I copied the list below. 8P0-907-279: 17 byte (base) 8P0-907-279-A: 17 Byte (Highend) 8P0-907-279-B: 21 bytes (base) 8P0-907-279-C: 21 Byte (Highend) 8P0-907-279-D: 17 Byte (Highend) 8P0-907-279-E: 23 byte (base) 8P0-907-279-F: 23 Byte (Highend) 8P0-907-279-H: 24 Byte (Highend) 8P0-907-279-J: 30 bytes (base) 8P0-907-279-K: 30 Byte (Highend) 8P0-907-279-L: 30 Byte (Highend) 8P0-907-279-M: 30 bytes (base) 8P0-907-279-N: 30 Byte (Highend) 8P0-907-279-P: 30 Byte (Highend) 8P0-907-279-Q: 30 Byte (Highend) So according to this list my car has 30 bytes base central electric module. Does that mean that it doesnt support footwell or ch/lh lights? If so can I get them working by changing the module to 8P0-907-279-K or L or N or P or Q 30 Byte (Highend). And is there any differences between those 30byte highend modules with different last letter? What about changing the module. Is it hard? Thanks for your help!
