For E92 owners with comfort access

A question:
The seatbelt arm works when there is power on, and the door closed. You get in the car, put foot on clutch, press start button and hold until engine fires. The seatbelt arm pushes the seatbelt out.

The seatbelt arm also comes out when you get in, shut the door and simply press the start button briefly without foot on clutch which switches the car onto accessories live - i.e. not the ignition with the idiot lights on.

In other words, whenever the door is closed and there is any sort of power on, the seatbelt arm works.

After two years, mine doesn't anymore - suspiciously after a software upgrade. Go in the car and immediately start the engine and the arm doesn't move. Open and close the door again, and it does.

If you put accessories on first and then start the engine it works. In other words, it works at the second time of asking, not the first.

Anyone else have this problem?

As an aside, for those without comfort access, does your seatbelt arm activate when you insert the fob? - or when you start the car?

"HOLD" start button until engine fires? No need to, just tap it and thereafter no need to touch it.

No idea on the CA bit though Alan, sorry.

Not entirely sure what your question is mate, but my seat belt arm offers the seat belt when I start the car. It offers the passenger the seat belt too if the passenger door has opened. Hope this helps.

No.
My question is this. If I go into the car in the morning, depress the clutch and fire up the engine, the seatbelt arm doesn't come out. But it always used to.

To get it to work I would have to open and close the door.

OR, I can just tap the start button without depressing the clutch (equivalent of the "accessories" position with a traditional key ignition) and then start the car - then it works.

And Dave, you do hold the start stop button a little more than just a tap - especially when cold - it's the equivalent of holding an old style ignition key against the spring. Your car may start very quickly and seem almost instantaneous but an even lighter tap will just put the accessories on. (Over this winter, you will have seen the coil sign come up on a cold morning before the engine started - whilst holding the button in the whole time.

I've never seen the glow plug symbol come up on mine Alan, even though we've had -8 temps down here.

No need, it'll fire once the glow plugs are happy, so long as you have kept the clutch depressed even with a single press (rather than hold). Seen it a couple of times, but then we didn't have temperatures quite that low before the old denzil departed.
