Good Day, Season Greeting to all.

The Start/Stop Function on my wife's 2016 X1 stopped working. Does cold weather and or snow have anything to do with its operation.

Typical causes of failure

Did you/she push the button next to the ignition start button? My wife did that and it turned on the start/stop feature. Ours is turned off as it's beyond annoying.

Yes.

No reason to have the engine off when you are blasting heat into the cabin due to cold weather.

Everyone wants to be climate friendly until they are cold.

All stop/start functions reset the next time you turn the ignition off and on again. So it is on by default when you start the vehicle.
Also in Sport mode the start/stop is disabled.

One point to remember, if your battery condition is low, then stop/start is also disabled.

Millie, so what you are saying if its cold outside the Start/Stop is deactivated by default (if you have the heater on or not)?

The Start/Stop is On as the Symbol in the guage cluster come up when you come to a stop but the engine continues to run and the revs do not drop as they would have normally.

[CnSky]

The symbol is only lit when start stop is deactivated from my recollection.

It's telling you it's not available likely due to cold temp or battery condition.

[Glen e]

Start start functions actually pretty smart. There are 21 things conditions that have to be met before it will negate the start stop. Low battery condition, is one, another is if the cabin is not above or below the temperature set in the climate system it will not shut off, so in the summer if it it hasn’t reached the optimum temperature with AC, it won’t shut off, converse is true in the winter.

I don't know how it works exactly, but it's likely a function of outside temp, vehicle temperature and climate control setting. If certain parameters aren't met then the vehicle won't shut off. I'm sure it's in your owners manual the conditions the vehicle needs to shut off.

It's -30c here now and even with start/stop enabled, cabin set to auto at 21c and vehicle temp warm, it won't shut off at a stop or light. I wouldn't want it to anyway as these vehicles cool off very quickly if not driven under load in these temperatures.

Mine shut off 2 days ago while I was monitoring the 'battery discharged restart engine' issue. I put it into eco pro hoping to use less battery power and at the only stop I made the engine turned off and restarted as it should when the lights turned green. Not a simple vehicle to understand etc are these BMW's. My wives Equinox starts every time drives around town in -20c to -35c all day long stopping here and there and starts perfectly every day !!
HNY to you all.

Ecopro is to reduce fuel consumption - aka turn engine off when able. I normally drive around in sport because I hate the comfort mode throttle response, also so the engine doesn't shut off in -30c. These cars seem to be finicky in really cold weather like this, likely due to all the electronics.

Our lease is done this summer and the X1 will be gone for a real SUV with a V8. My Camaro has zero issues in this weather when I drive it and the big engine warms everything up 100x faster than the turbo 4 in the X1. Murica!

[24448640]

Don't like finicky either but I only got my X1 in September so I'm going to figure it out or struggle. It's sat outside plugged in it's -27 and I plan to start it on Sunday when the temp is expected to get near zero here!!! Love the X1 otherwise.

Some BMW Stop/Start operational parameters:

Some reasons why the engine does not auto-stop:

• the car has not reached 9 mph for automatics or 5 mph for manuals after starting
• the vehicle is rolling (manuals)
• the brake assist vacuum is too low (manuals)
• the transmission adaptation is active (automatics)
• too little pressure is being put on the brake pedal, the vehicle is therefore not detected as being sufficiently stopped(automatics)
• the hydraulic pressure accumulator doesn’t have enough pressure (automatics)
• the driver has unfastened the seatbelt
• the engine is not at optimal operating temperature
• the battery charge is too low
• the ambient temperature is under 3 °C ( 37.4°F)
• the ambient temperature is above 30 °C (86 °F) and the air conditioning is on
• the climate control is on but the interiors didn’t reach the desired temperature
• the vehicle has stopped downhill or on a hill with a 12% or higher gradient
• the HDC (Hill Descent Control) is activated
• the steering wheel angle is above 6°
• the steering wheel is being moved after coming to stop
• the accelerator pedal is pressed
• the car comes to a stop after reversing
• the driver leaves the car
• the DPF is clogged
• the fuel is of poor quality
• the IHKA system detects fogging of the windscreen
• the ABS system has been activated

BMW default auto start-stop

At times you may notice the auto start-stop restarts your engine despite the fact you haven’t started driving yet. Below are some things that may trigger the BMW engine to restart automatically:

• the car battery is being discharged too quickly
• BMW starts to roll with the engine turned off
• the temperature inside your vehicle changed from the desired temperature
• the temperature inside your vehicle is too high
• the gear lever is moved to Reverse, Neutral or Park
• the steering wheel is moved while the engine is off
• the ‘A off’ button above start-stop is being pressed

These all seem like good reasons to not allow the stop feature.

Any idea what the DPF is?

Diesel Particulate Filter.

Thank You

[PurePulse64]

Have your battery checked, mine stopped working but the car never indicated the battery needed to be replaced. The dealership said I needed a new one, sure enough it started working after a replacement battery.

Is there a possibilty to disable this function more permanently?

Thanks.

You can delete it permanently with BimmerCode… Start searching here lots of posts…

16s actually had memory on this button. It's the reason I started coding my x2 because that went away.

I haven't a clue what you are saying. Please enlighten me.
Note.1 The statement I made is a fact.

[billnchristy]

If you turn off ASS in any mode on 2016 x1 the button stays off and does not reset.

This changed in my 2019 x2 where I had to code it off.
