Hi,

I have bought a CLS350 C219 (2004) car, but Keyless GO system doesn't work.
Suspect was the key, but wit the new key (ordered from Silver Star, official MB dealer in Bulgaria) keyless system does not work again. /old key was in terribly condition/

Connected to STAR diagnostic, and it says:

9016 Keyless Go fault: No feedback received from left side door module
9017 Keyless Go fault: No feedback received from right side door module
9018 Keyless Go fault: No feedback received from interior compartment module
9019 Keyless Go fault: No feedback received from rear module

Fuse is OK, relays are OK.... any ideas?
I suggest keyless system is disconnected from the car. Where to check this? In from SAM or rear SAM module? or somewhere else?
There is no way all 4 modules to be failed I think.
