Auto start/stop feature not working...
Hi all,
I've just picked up a F20 116i a few days ago and noticed that the auto stop/start isn't working like it did in the demo car that I drove. I've read various things on this with some people saying that the battery has to fully charge before this feature kicks in. is that correct? I have driven it with the aircon off and also in ECO mode but it has never stopped in traffic like it is meant to. thanks |

There is a list of conditions when it doesn't operate. Check those in the owner's manual. These include engine not warmed up, outside temperature below/above certain level, engine warmed up, being in sport mode, too low speed, air con setting etc.

Yes, I have checked all those. It's a mild summer in Australia so its just nice weather. I've tried it with the aircon off. Tried it with ECO mode. Also sat in traffic for almost 10 minutes and nothing happened.

When you turn on the ignition however, it is supposed to engage the start/stop function automatically - unless you have commanded the iDrive to set it up differently.

Make sure you are stationary in neutral with the clutch disengaged.
Providing auto start stop is switched on, it is above 3 degrees and the battery is sufficiently charged it will auto stop. If it doesn’t stop immediately after bringing the clutch up, it won’t stop at all no matter how long you wait. You’ll have to put the car in gear, move, come to a dead stop again, put in neutral and bring the clutch up before the software will trigger another decision whether to auto stop or not. If this doesn’t work, go back and see the dealer, it’s broke.

It's an auto transmission.
THe car has only travelled 170km since I picked it up the other day, so perhaps it needs a while before the stop/start begins to work? |

I think that would be the problem then, i was under the impression that it only worked on Manual cars?

That's odd, i was sure i had read that it wasnt on Autos so i looked on the website (see below) Maybe this is old information?
Implementing Start/Stop on an auto box was traditionally more of a challenge as the engine must restart instantly when the driver moves from the brake to the accelerator.

These two explain a lot of the behaviour i have seen when i have wondered why it didn't work.

"Auto Start-Stop Funktion i Verbindung mit Schalt- und Automatikgetriebe" Meaning: "Auto Start-Stop function in conjunction with manual AND automatic transmission" So the text from the web site you refer to is obviously outdated

Hi all,
Thanks for the replies. I did speak to BMW who have suggested that it may be related to the fact that the car is still new and the battery hasn't had time to recharge fully. The demo car I tried worked flawlessly and was quite impressed, so I'll drive mine for a few more weeks and see if it begins to work then. By the way, it's a gorgeous car....thoroughly enjoying the 'sheer driving pleasure' hehe |
