Comfort Access Weirdness
In the last few days my CA-equipped M3 has started to unlock itself as I approach the car (normally this happens on the left side, not the right, as I get close to the door mirror) without any pressing of the key fob button.
At the same time however, it seems reluctant to unlock/lock when I put my hand on the relevant door handle sensor (either side). The other weird symptom is that for a few seconds after the strange unlock, I can hear repeated, slightly irregular clicking inside the luggage compartment. This clicking happens 8 to 10 times over maybe 20 seconds, then stops. I have tried both key fobs, and exactly the same thing happens with each one. Also, if I put the key fob inside an RFI wallet, no unlock happens (so at least the wallet is working OK!). Any ideas?

I have the exact same problem with increased battery discharge. Did you find out what the problem is?

My battery just shit the bed (it was 10 years old) and CA was the first thing that started acting up noticably. Couldn't touch the door handle to open the car.

A089 A091 A094. Cleared them and they were back today. I wonder if my handle is shot and draining the battery. Thanks for the reply and input. My lucky is both. Battery and handle 😂👍. My problem is I don't drive it much. Just put it on a tender. I think I waited too long.

I am fairly certain that this is exactly the same problem/solution that I had about 5 years ago, on the same side of the car, although symptoms were different then (no phantom unlocking, just a refusal to lock/unlock on touching the sensors). So the handle does seem to have a limited life-span. As I recall, the antenna is only in the left-side handle. I blame our shitty wet climate. For this and other things...
