comfort access worked sometimes, but i just wanted the key fob remote to work. Then comfort access stopped working. I just about gave up using this car. Proximity did not work either. If i want to push the button of the lift gate to unlock or raise the lift gate, nothing.
Then last month, I pushed the button from inside the dash to raise the tail gate. Afterwards, I noticed the key fob remote would work. However, it would not work when I returned. For instance, just going into a grocery store, the remote would not work. I had to use the physical key to unlock the car.
Other times the remote might work the next morning.
Last week I took all the door handles off and disconnected the harness, I left the wires free. I did not cut anything. I will say I did get error codes that all the CAS doors were a problem before doing this. Same problems. intermittent use of the key fob remote. Strange, all doors except the driver door still closed with assistance. Yesterday, I reattached all the harness. Comfort access worked except the drivers door. Had an early instance of no high battery drain. But it came back within an hour.
I did look at the diversity antenna. I removed it and checked the circuit board. there was no recall corrosion to note. I do notice that when the key fob remote is not working, just pushing the lift gate button from inside the car will allow the key fog to magically work. However, if i come back from leaving my car parked, the remote might not get recognized. Then I am back to unlocking with the physical key.
this morning everything seemed fine, but when i got to work and turned off the car, (key was in my pocket and car started without being in the slot), the car said it did not see a key. I pushed the tailgate button to open and then close and the remote worked again. Did not have to put in the slot.
My thoughts are the CAS is a problem but also something in the tailgate.
Any thoughts?

Do you have a second fob? Does it work or is it the same? Maybe the NFC in your fob is going out? I'm dealing with this right now in my G80.
