7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

At times, it's Comfort Access

And other times it's just a regular door. Not a mission critical issue, but 3/4 of doors work most of the time with comfort access - no key, just pull slightly or nudge the handle to lock the doors and engage the alarm. The rear driver-side door seems to be on vacation.

Lately, it's been spotty, as in 75% of the time it will work as it should but the rest of the time, no response, no vehicle alarm engagement either. The remote lock/unlock works fine though, as does the soft-close door feature. I changed the remote battery to a fresh one, so it's not that. No errors showing anywhere. No doors flying open while driving either (phew).

So I'm thinking it could be a bad antenna or control module, but the whole intermittent nature of the problem begs the question is something else factoring into this? Bluetooth phone maybe? It doesn't seem to be location specific (garage versus parking lot or other cars around).

i know I'm probably wrong when i say this but it worked for me...try putting your key in the starting slot next few times when you're driving...mine was acting up and i put it in and it fixed the problems.

probably a coincidence but worth a try loll

This same EXACT problem has been happening to me as well. and it's the rear driver's door that doesn't respond to the comfort access. and at times the driver's door doesn't open either. the key battery was good, and the key remote worked just fine. I Pretty much always have the Key in the FOB slot. I solved it by switching Keys. but still, if anybody has any suggestions, please post em. I'm still under CPO warranty, but I bet the Dealer will just say they couldn't replicate the problem.

thanks in advance for any further help.

i had a similar issue with my 06 Li driver's side rear door. Finally the door wouldn't stay closed at all, they had to replace all of the latch system. I ended up having to tie the door shut!

Fyi, for those not under warranty, this is a very easy thing to fix; there is a piece near the interior door handle that commonly breaks -- similar to the hood cable type of break. 15-minute fix at most.

Update

Driving a few times now with the current key fob in the ignition slot. This morning, had the same problem, comfort access lock and unlock on the rear driver side door didn't work. Yet it did work as normal using comfort access via the driver's door.

I'll switch to the second fobbie this weekend and see if there's a diff. I suspect Keif might have identified the solution there with the broken handle component. Hello CPO coverage.

Thx for all your responses, glad I'm not the only one seeing this issue.

In the shop now

She's at the dealer now. Of course when I was dropping it off and trying to re-create the issue to the SA, comfort access worked flawlessly... all ten times that I tried to show that it wasn't working!!!

It's like the car knows it's at the dealer. SA said they'd check for faults anyways.

Now I noticed something when I was there. Maybe you have too: I have a building access fob on the same keychain as my 7 key. It's a proximity-based fob, ergo, it's RFID and thus transmits/receives RF signals from the access panel at the building door. It's not battery powered as far as I can tell, so it's a matter of inches in terms of the operating bubble. When I was at the dealer, I had the 7 key separated from the fob/rest of my key chains. Could it be?

Anyone know if there's any cases of interference here with comfort access outside the vehicle (engine start/stop in the vehicle works, no prob)? It's always been an intermittent issue - never a continuous hard stop malfunction. There's no operating frequency on the building fob, so I'm speculating here. I've got wifi at my house, but it's nowhere near the car, and is in the 2.4ghz band. Cordless phone is in the 5.8ghz realm too. Hmmm.

.
Just started happening to me whenever new neighbours park next to mine with their new RR or RS6 - only if they've gone before me in the morning, so I suspect it has something to do with the remotes on the RR/RS6 messing with the CA. OK 100% of the time otherwise. No real biggie, just a touch annoying...

Hmmmm....I'll bet your on to something. Seems logical that there could be some type of interference.

Software update for now

Got a call from the SA early this evening. There is a fault showing with comfort access. He said they were going to perform a software update on it first to see if that resolves the issue. Said it was between the comfort access antenna and the car. Next step would be to replace the antenna or other hardware involved.

Had the SRS/tensioner alert pop up in the last week or so too, and he mentioned that was going to be a software upgrade too. Just one of those weeks I guess.

I've got a 335 sedan loaner, which is quite the corner carver compared to the 7. It doesn't seem to grip as well as the 7 with ARS at the max, but the acceleration is very nimble and pleasantly torquey with the turbo. And I can't tell you how much tighter the tranny feels on it. More reassuring shifts.

Sure, this thread pops up, I post that I had the problem with the driver's rear door before, and today the driver's door CA fails. Son of a beotch. I love this car, I hate this car. At least it's covered under the CPO warranty, goes in next week.

I hear ya. When it's running it's really running well. Otherwise, the seat in the BMW Service waiting room is beginning to perfectly mold to my arse.

So the car is back. The CA parts are on order from Deutschland. Covered on the CPO warranty. SA said there was a voltage fault as a result of the problems and was impacting the SRS system, hence the popup alert on that component. Lovely how that's all connected in such a manner.

I've had a grounding strap problem before, wondering if that's playing into the vehicle randomly shutting done other systems now. (When the strap went or broke, the transmission crapped out and I got the "reduced or limited engine power" and "only forward gears (sic) are available".

Meanwhile, CA worked today but not yesterday. Go figure.

Glad to see this covered by CPO as my normal warranty runs out in 300 mles.

I wish all service advisers would link a problem DEEP into the cpu system to detect it...creating it as a CPO covered problem instead of "door handle" out your pockets problem..that would be sweet

Checked the BMW site for warranty info

I noticed the special offers tab. Now I have to wait till morning to see why I was not offered the 0.9% financing. I bought within the window, but BMW USA could not tell me if my dealer is participting in this program, I have to ask them.

I asked my SA three times if it was covered, he said it was, just the $50 deductible is all I will be incurring on this one. They did check the modules overnight to see if this issue was stemming from that.

It's sorta Comfort Access

Well, three door handles and antennas later, I'm still having the same problem. It worked for a day or so and then back to "only works when it wanna".

Going in again this weekend for another looksee. The write-up on the first ticket had lots of references to faults, over-voltages and having to recharge the battery a few times. Me thinks this is a major electrical issue here.

A few months back the grounding strap(s) had to be replaced and I'm wondering more and more about this car's integrity in light of these ongoing electrical issues. Only has 62k on it and was looking forward to replacing the "consumable" suspension components next year in hopes it would be working perfectly at that point. But alas, foiled again. Fingers crossed.

I still have faith, in the car and the SA. When the car is running well, damn it runs great. But fickle things like this keep me suspicious.
