Stop/start when slowing and stopping...

[Marsh]

It’s a VAG thing, when all conditions are met it will do it.

Sounds perfectly normal.

Every car I’ve had with stop/start does this if you are slowed right down but still creeping forward. It’s normal, working as designed. Was the main reason I always turned off start/stop in my Mercedes, but now I’m used to it I don’t care so much about it in my Macan so I leave it on.

Nope. Our old X1 didn't do it, neither does my 981.

It makes sense to have actually stopped before switching off the engine and power steering, doesn't it?

I agree, and the start/stop function on my current, and previous BMW's only cut the engine once the car has stopped (I'd say there is about a second delay after stopping before engine cuts)

If stop/start is cutting engine before coming to a complete stop, it can only be faulty or is poorly designed.

Yep, I usually turn auto stop start off, but when I have used it occasionally on the 911 it will do this sometimes. It depends how you come to a stop, if slowly drawing to a halt and releasing the brake a few seconds before rolling to a stop the engine may cut before you stop. I don’t see it as a fault and I suspect the OPC won’t either.

Funnily enough Nick when I'm slowly drawing to a halt, I release the brake to stop the engine cutting out. I particularly use this technique in stop/start traffic when I can see the queue is starting to move and I want to prevent stop/start activating. If the queue is long then I turn stop/start off but as I like the "cruise" function I normally leave it on. It was so much easier with the SD because I used the diamond button to quickly turn stop/start off but I'm using that button to turn on surround view when exiting blind junctions.

AS a digression, my wife's Tiguan stop/start also cuts in if slowly braking to a standstill. What's even more annoyiing with that system is if the car has been at a standstill for more than a second it wont restart until the throttle is pressed. Just releasing the brake has no effect (the car is still held by the auto-standstill brake).

Doesn't the auto-standstill brake only apply if you press the brake pedal really hard, as was the case with my E-Class? Just seems odd it would apply every time the Tiguan stops?

Mine has to definitely come to a complete stop before it shuts off. But I have a different scenario, because I'm so gentle with the brakes, on many occasions it doesn't switch off at all.

I wonder what sensor/s activate the engine shut off when forward movement stops?

The Tiguan auto-standstill brake "does what it says on the tin" and doesn't require any brake application. It can be a pain during slow speed manouevering.

The auto brake will detect an incline or you can engage with two sharp presses of the brake pedal when stationery

The HOLD light will appear when engaged.

[Nuclear Nick]

^^^ Only one sharp press of the brake pedal is needed, but it can be a bit hit and miss in practice.

[Skyway]

Yeah, you're right, one solid press

Mine will sometimes turn off when under 5 miles an hour and the brake is being applied - ie, coming to a stop. My Audi did this also.

Best way to avoid this is to drive the car in sport mode. Then start/stop is disable by default !
