W215/W220 AC codes

Hi guys. AC has stopped working. I checked the diag and I'm getting codes:
"KLA A Error 1268" and "KLA V Error 1268"

Anyone know the difference between the kla A and kla V?

I found this in another thread: "B1268 Communication fault of A/C bus w/ control unit N18/4 (Center vents electronic control module)"

My codes don't have a "B" so I don't think they're referring to the A/C bus module.

KLA = Klimatisierungautomatik if you set Xentry to German
in English version, the only version people should read in Xentry to post questions, the module is AAC
KLA = AAC

B1268 Communication fault of A/C bus w/ control unit N18/4 (Center vents electronic control module

Ac error code KLA V 1268 on w220 s320 what does it mean. blower works intermittently.
