Weird non Comfort Access key fob battery error
I hope someone can explain what happened here, but this past weekend something very strange happened. I decided to use my secondary key fob which hadn't been used for a few months (I have always cycled them like this), but after I unlocked the car and inserted the key, I am greeted by a low battery error message. I then took the car for a 30 minute drive in the hopes that the error would go away if it is simply a case of the key fob battery being a bit low. This unfortunately didn't happen, and instead it persisted.
The following day I took the car for a long drive or approximately an hour and a half, and this didn't help either. This is where it gets strange - this afternoon I took both keys with me again, but instead of using the bad key, I put the good key in, and same problem! So now it's not actually the key fob, unless both failed at the same time, highly doubtful. Well, I took the car for a drive with the bad key since I had to go for a drive anyway, and on the way back I decided to stop and see what happens if I park the car and lock, unlock etc. So I did just that, I stopped, switched the engine off, removed the key fob, then without getting out of the car, just unlocked and then locked the car - sat still and waited about 30 seconds, then unlocked and opened and closed the driver's door. Now this is where it gets interesting - put the bad key fob back in, no error! Remove and put the good key fob in, no error! So what on earth was going on here?! I don't drive the car daily, and I have been battling with an intermittent battery drain issue for quite a while now, so the car is always parked in my garage with the bonnet (hood) open and therefore the car is never locked and alarm never set. Could this have caused some confusion when the secondary key was all of a sudden being used? I am going to keep an eye on this to see if it reoccurs though. |

Well, not using photobucket anymore - they've stopped allowing pics to be posted on 3rd party sites. Oh well, guess I won't be using photobucket in future...

I had the same problem with my KEY FOB....
I had the same issue with mine about 2 yrs ago and it led to a shit show of events........the keyfob said it was dead(I only have 1) and I don't have Comfort Access so I searched and searched online for a video on what to do then I found some dumbass Russian dude who made a fake video about replacing the non CA FOB battery and I didn't know it was bullshit until after I did the breakin of the back cover on the FOB so I glue my cover back on and try to start my car and everything works fine except the battery warnin light for the DEAD FOB AT this point I figured OK im dumb but I only broke the cover NO BIG DEAL RIGHT???? yea then the real shit show started I go to pick up my cousin at his work at 3am and I pull into the parkin spot and shut the car off..........my cuz gets in and I go to start the car and NOTHIN....NOTHIN AT ALL!!!! Do u know how hard it is to get ahold of a tow/auto club @ 3am??? yea so I waited 4 hours for these fools to get me WHAT I find out while waitin for them to pick me up was the IGNITION was dead.....the STEERING WHEEL was locked turned to 1 side ..... LOOONNNNGGG STOOORRRY SHORT------ I found out after that theres a issue with the steering column and ignition lockin due to an issue with the CAS system I went to BMW to find out what they would charge for the repair and I was blown away when they told me they wanted $2500 bucks for replacement of the whole steerin column YEA EFFF THAT !!!!! so I found a few great guys on this forum and I got someone out in Poland to remote access my cars ECU via the OBD port and was able to restore the factory CAS settings....for $55 bucks !!!! unbelievable that the stealer ships can do this to their customers I HOPE THIS ISNT WHAT HAPPENED TO YOU!!

I am hoping this was just a random issue caused by the secondary key having not been used for a while. Will update after I have driven the car a few more times without further issue. |
