Hi All...

For some reason my stop / start function has stopped working the past week , no warning lights or messages.. It is a auto box.. Anybody else had this issue ????

[Merc for hire]

yes, if weather is too cold. it stops functioning.

[cliveywolves]

Mmmm it's been fine weather wise and worked in previous months when was colder and frosty.. Even at peak temps it still not kicking in like it would normally

Did you accidentally press the button that turns it off? I did this the other day as the button is right above the engine start button.

When you say it's stopped working:

Do you get the "no auto stop start" icon in the gauge cluster?

Is the ASS off button lighting up?

I noticed a new reason for ASS to deactivate compared to my previous E82 (manual gearbox) on my new F22 (auto gearbox), non-zero angle of the steering wheel.

I do have a Stop & Start problem, but different from yours. It sometimes (from day 1) turn into a Stop, Start & Stall system. After stopping at a traffic light, when I release the break pedal, the motor restarts then shuts down immediately. My BMW garage has the car for 3 days, I hope they'll find some reason...

Sure... Good to know I'm not alone in the world : . I posted my problem in a French forum but got no interest. Only answer was "turn it off" it's useless...

I occasionally had that happen on my 335i but I don't know if there was anything specifically "wrong", or just a bad combination of timing.

The Auto start on the 2 has been much smoother than it was on my F30 though, so for now I've been leaving it on.

I came to post a comment about an annoying difference in start/stop behavior between my wife's F30 and my M235i. Your post seemed a perfect cue :-)

Both cars are auto. In the F30, the slightest reduction of pressure on the brake causes the car to restart. The car is ready to go by the time I get on the gas--I would have to work hard to beat it. (Assuming I don't left food brake, which I'm not in the habit of.)

The F23 doesn't restart until I completely release the brake. I almost always beat it to the gas, and get a noticeable hesitation before the car starts. This happens pretty much every time I come to a stop, and it makes the start/stop function much more annoying. (even though the 6 starts more smoothly.)

Have others noticed this, or is it just me?

You can also trigger the engine start by forcefully move the steering wheel a little.

I think it's just you...

My f22 reacts like your f30. Slight release of pressure on the brakes and engine will start again, and vice versa only slight pressure on the brakes won't activate stop/start only hard pressure.

I'm still getting used to the stop/start function, still feels unnatural to me

Not just you. Mine is the same...i beat it to accelerator application. I find it quite annoying.

Good thing I usually drive in Sport mode.

Interesting. Another difference I notice is my brake pedal is considerably firmer than on the F30. One of my gripes about the F30 is the brakes feel mushy to me. Does the Australian market M235i come with the M-Sport brakes?

I tried some more this afternoon, and I cannot make the engine start with the brake pedal short of completely releasing the brake. I wonder if this is adjustable?

Yes I get the crossed out icon pop up on my display and the start stop function is not turned off on the dash.. ?

Yea m235i in Australia only comes with all the m sports packages as standard.

My mate's dad got a 435i and it is a little mushy.

Overall, it's very similar to me.

It could be your aircon is turned up too high... Maybe your not braking enough for it to charge... Are you in sport mode? As stop/start only work with comfort and Eco mode.

It's a new car take it to your dealer.

[cliveywolves]

No think it's just broke.. Don't really run air con .. Booked in dealers

[bimmerfile]

I wish my auto start/stop would stop working - permanently..

As mentioned if the icon is popping up in the dash, it may be more likely that some other trigger is causing it to not stop.

If you aren't running the AC it could be a battery that is low on charge. If the battery charge is low it will not stop the engine.

Do you do a lot of city driving, or short distance driving? If the car doesn't get a long drive to keep the battery charged enough (or if the battery is going bad) then that may be why it isn't kicking off.

Your dealer may have a tough time to diagnose it if it isn't throwing any errors, they may just have to drive your car around for a while, and personally I hate knowing that my 300hp car is turning into the managers hoop-d for the evening or the 17 year old tech's vehicle to go pick up lunch orders.
