Exclamation BMW 318i E90 start stop sequence Incorrect

Hi, looking for help with a 2008 318 E90 start stop issue please. Since having the car the function has never worked correctly.
As I understand it, to engage a stop, it's stop car, clutch in, select neutral and cuts out...... Correct?
Mine I accidentally got to engage when I stalled it! So in short I stop car, car in gear, lift clutch and cuts out. To restart I then select neutral and engine starts.... Then obviously go into 1st to continue the journey.

Anyone experienced this?

Battery is getting replaced tomorrow although I've not experienced any other loss of features.

I know start stop devides opinion but it's just doing my head in now so want it to work out of principal!!!!!

Not sure if you have deliberately left out steps or if you're misinformed. The car will never auto stop with the clutch pressed down.
It should also never stop in gear.
You should get clutch pedal travel sensor and zero gear sensor calibration checked

Apologies I originally said clutch as a step I should have maybe been clearer. I mean On a manual transmission BMW, auto start-stop activates itself as follows: first, stop the car and press the clutch; then, shift the gear lever to neutral and release the clutch. At that point the engine will turn off. Obviously mine isn't doing that unless I stall the car which does activate the icon on the display and cut the engine. Coming back in to neutral to restart I know is 100% wrong.

Thanks for the suggestion on those 2 sensors 👍🏻

Auto start stop will automatically restart the car if you stall - I think that's what you're experiencing.

Thereís a number of factors that affect stop-start. The battery, the sensors that detect the gear and clutch position, the external temperature, and so on. Mine stopped working when my battery started playing up. I changed the battery and it works most days, except when itís cold outside.

The vacuum sensor on the brake servo was what held up my old one.

Cold weather hindering it makes sense as it'll keep the engine running to maintain battery voltage, coolant temp, etc.
