Comfort Access Problem - FIXED
My car likes to make me wait in regards to the Comfort Access; when trying to lock and unlock with the door handles and the key in my pocket, it never works on the first try. Sometimes it's the 3rd try, sometimes it the 40th try. The problem occurs with all the doors and the trunk, and also with both keys. I also frequently get the "Remote Not Detected" message while the car is running. Anybody that can shed any light on the situation, please do so!
EDIT: Problem solved! I diagnosed the car with ISTA/D and sure enough, it showed a Comfort Access fault, specifically with the center console front antenna (or "aerial" as BMW calls it). I saw on the car's service history that the cup holder in the center console had been repaired/replaced at one point, and I assume that the tech did not hook up the antenna when reinstalling the console. Pictures below! Last edited by UA_civ_eng; 03-29-2016 at 02:22 PM.. |

If both keys produce the same problem then I would think the sensors on the car itself are either faulty(not sure how common this is, I know there are multiple ones all over the car) or there's interference from another source. Never had that issue before personally but looking into that would be my next step if it did happen with my car...

One interesting thing: At night time, when I walk up to the car with the key in my pocket, as soon as I touch the door handle, I see lights come on on the parking brake button and the emergency flasher button. Without the remote near, touching the door handle, those lights don't come on. So this tells me that the car knows that the remote is nearby and that the door handle is being touched, there is just a piece missing from the puzzle for it to send the unlock signal to the doors. |

Just a thought: I've experienced a similar issue on several occasions, and realized the culprit was me carrying my key fob in the same hand as my iPhone. Once I separated the two, problem solved...
Is your smartphone anywhere near your key fob when Comfort Access acts up?

Ive noticed if my key is in the same pocket as my phone and even occasionally my wallet(i suspect my id card for getting into the building at work) it sometimes takes a few tries.

I have had the similar issue with phones and wallets blocking signal. However, never had any issue with touching both lock and unlock. It seems more like a sensor issue if you are holding both keys in hands. I would doubt it is a battery issue as well.

Help-CA
Sorry to drag up and oldish thread but I have a very odd CA problem...the two front doors will not lock using the ridges on the handle, but both rear doors work just fine...where exactly is the antenna...you say under the centre console, but could you be a bit more specific for me please...is it under the trim that houses the gear lever and other buttons or inside/underneath the centre armrest cubby?? I'm hoping it's just a loose connection or a faulty antenna because I tried a new handle and that didn't sort the problem at all...weirdly, it does work very sporadically...reckon I should look at the antenna...but realoem seems to show there's a different antenna for each door (so four the doors and a 5th for the trunk/boot)....I'm really confused...if I pull the front handle, the door does UNlock but it's not Miron sensing, more mechanical the the back Doris that open when I first slip my hand behind the handle without even pulling it...
