2003 CL55 AMG Renntech Door Locks
Hello, Im new to the Mercedes world but I could not pass up on buying this car/beast. The car has a few issues but I want to start with the door locks. My doors will not lock or open using the key or buttons inside. I have to manually lock the doors. Any ideas???
Thanks
Al

My initial guess would be your PSE (Pneumatic Support Electronics) pump that controls that circuit is bad or has a leak that shut the circuit down.
Pull the 20A fuse that controls the pump which will reset the circuits. Then try again.
Or have the system scanned and see what codes are being stored.

The fuse is located in the fuse block below the rear passenger seat leg area. You will see the cover. It is one of the yellow 20A fuses on the top row towards the middle. It is OK to pull both one at a time then replace after a few seconds.
The pump sits behind the carpeted paneling on the drivers side in the trunk.
