I noticed a couple of times last night, stuck in traffic, that my S/S didn't kick in. I don't understand why. Then eventually a couple of hundred yards along the queue, it did! Very odd.......

Anyone else's do that?

That's funny. I noticed the same thing on my way home last night too. I wondered if I wasn't pressing the break as firmly some time and was maybe creeping a little (desperately hoping traffic would move!). I thought it was just me!

But I was actually clicking on the handbrake when I was stationary so was definitely at a halt :)

At least it's not just me!

It's very vehicle condition dependent ie state of battery charge, temp air on use etc etc how warm or cold the engine is all alter whether it will occur or not. Clever cars.

The stop/start has always (ie, R56 too) had a minimum distance before it works - something like 50 metres or so. If you are crawling forwards half a car's length at a time, the ECU thinks you don't want the engine to stop each time, so it keeps the engine running.

Ah brilliant, thanks guys ..... another case of the car being too clever for it's own good ... there was me thinking it was just being tempremental!

I think the owners manual lists the conditions under which start stop will deactivate. These are very clever cars. A friend has a mini cabrio. 2012 model and the roof stopped working and other stuff shut down. Went to the dealer to be told that because of the very very short runs she was doing,literally 2 miles to work and back the car was slowly shutting off none essential operations to protect the battery. A long run sorted it by charging the battery! And the f56 is even cleverereerrrr!!!!!

If you select the minimalism display (not the fish, the one with the diagram of the car) and you switch the split screen off, then it displays a message that says why the stop/start has not engaged.

I've seen one about high AC requirements and one about "driver intervention" (or something like that).

As Jeremy says, there's a list in the manual and it includes when the car decides it's in stop start traffic, which could be the distance threshold that Angib described.

Just to add to Mark's comments. I have no idea of this works the same on the MINI, but on my BMW X3 (Automatic), I can make it not switch off by giving the brake a sharp jab just as the car is coming to a stop. Then the display will read something like Start Stop not active - Driver request. Possibly the mini has something similar. Also, the BMW sometimes gets it wrong if I have to brake suddenly, or modulate the pedal in different ways.

But of course this is all just speculation :D

That is too cool. An amazing amount of clever software in these cars.

If you turn up the climate above 26C I think it deactivates the SS too (since a stopped engine isn't heating the car!)
