Hello,

I have an Audi A4 B6 Avant. The problem i am having is the remote central locking range, it only works if you’re very close to the CCM module. Literally right up against the passenger window for it to work. I have checked the CCM module for ingress and the wiring, and wiring up at the passesnger door , switched batteries in the fob, checked for any fault codes with VCDS, all ok.

Is there anything else to check or is the CCM faulty?
