Weird ASS issue
Hi guys 'n' girls,
Had my X3 30d since Dec and over the last few days I've found that the ASS (Auto Start/Stop) won't kick in. I've tried everything I can think of and it just constantly shows the crossed out symbol in the display and if you go into the appropriate page in iDrive, it shows "Engine Running: System Request" whenever ASS normally would initiate. This would normally happen on a cold morning when the heating is on, or a hot day with the aircon on full, but none of that applies here. It's now been 3 days without ASS initiating, anyone got any theories on why this might be the case? It's a bit colder at this time of year in Perth, West Australia, I was thinking that may have been it, but it's not THAT cold and it's 15C+ when I drive home, so ...

LOL, I know you don't know me, but give me some credit - no, I'm not, I'm in Comfort, Eco or Adaptive. It's the same in any of those modes.

Something must be wrong.
My F31 30d do ASS even in Swedish winter, < -5C, as long as all conditions are met. I.e. engine temperature is little bit warmer than cold start, and the passenger heating unit has done most of its work. /n |

Possibly, but behaviour now is as it's been since Dec, so unlikely. But will see how it is after some long trips soon.

Haven't had car long enough to definitely say, but I have noticed on one or two drives to work while in eco pro mode it didn't shut off for extended periods which surprised me (as some previous drives turned off a lot). Pretty sure I went for nearly 20 minutes without it shutting off. I'm assuming there is some logic around battery, etc. I did have seat heaters on normal setting, but I may have moved them to full 100% power at some point, and wondered whether that did it?
In any case, it does still stop and start on other drives, so I've just put mine down to car saving itself. But maybe if you are in start/stop traffic over many days then it might need a look at (do you get start/stop traffic in Perth?!?!? ) I'm petrol too, not diesel, but doubt that would make much diff. |

I'll add a request for some way to check battery status in iDrive in the LCI Wish List (a % number like our mobile devices, not just 'good' or 'charged'). |

I have a similar issue; ASS won't kick in, no matter how long I drive or outside (and car) temperature is..... At the dealer they re-programmed the car and replaced the battery ..... no result yet... Car goes back to dealer next week... leaves me with an uncomfortable feeling "what is all wrong...." |

I’ve been meaning to update this for a week - my ASS is back after I went for a couple of longer drives and made a point of having heating off for a while. So can only suggest that it was battery level, yes.

My money is on battery drain somewhere in the system. Take it back to the dealer. Let them sort it out.

It's not the PowerMagic thingy is it? I do a lot of stop/start (A LOT!) most days and big runs only now and again but haven't had the issue. And it's probably colder here on east coast so we have front and rear seat heating most of the time along with heating and two kids running iPads for hours a day...

It may be, I’ve turned it off for now. I wish there was an indication of battery charge level. The Powermagic never seems to shut my camera off before the battery protection kicks in. Maybe it’s faulty. Ho hum.
