I have a 67 plate 1.4tsi DSG and noticed that start stop is very quick to activate, and can actually stop the engine whilst the car is still moving albeit very slowly. For example turning right, indicate, and moving slowly with my foot on the brake pedal, but not enough to completely stop the car and moving at a very slow crawl. waiting for oncoming traffic to pass the engine stop/start will activate. I was alway taught never to have the wheels turned toward the junction when waiting in case you are hit behind and pushed in to oncoming traffic, so the engine stops and you can’t turn the wheels before the engine restarts so feels hesitant at junctions. I know it can be turned off, but I’ve never had a car stop so quickly or when the car is still moving very slowly. If the system works off the ABS sensors why would this happen and can it be changed. I would much prefer a second or 2 delay before stop/start activates.

This has been discussed before but I can't find the thread. Owners of later models such as yours complained it's too enthusiastic to cut out the engine.

Sorry yes, just found the other thread. 
 

 

It is pretty fast on my car too, sometimes too fast to stop it and too slow to restart occasionally when the car just sits there "thinking" about it! I've had problems with my car off and on ever since I got it and blamed it on the 1.5 engine, I'm kind of wondering now whether the stop/start system is partly to blame, when you try to drive away after pausing at a junction, only you can't as there isn't any power, engine lights on, car not stalled but nothing happening. This doesn't happen often, maybe once a month it will leave me like this and then just wake up again. At other times it has what I'd call micro hesitations, when you try to move and the power falls away and then comes back again. I've never had a car behave like this before. I'd honestly rather have a good old fashioned diesel engine that just works, than a complicated petrol engine that often doesn't work...

A feature of newer vehicles is to stop the engine prior to a dead stop think it first came out with the Superb MK3. Yes it is a pain I always turn stop start off myself driving style for many does not work well with what this is trying to achieve.

It's positively dangerous on an automatic, you coast up to junction, see a gap and boot it, only for stop-start to have kicked in and the engine dies then it starts up and the gap is no longer large enough. Or someone flashes you out and at that second you engine stops and you have to wait for it to restart.

 

I agree, it should only kick in X seconds after a complete stop, not as you are still slowing down. I'd love to know if those parameters could be adjusted in VCDS

I've been trying different braking techniques. If you brake down to say 5mph then back off the brake pressure slightly and hold the car stationary with that light brake pressure, Stop/Start doesn't appear to kick in. I've tried a few times now and it seems to work, but does take some getting used to. If you apply greater pressure at that point then Stop/Start will activate.

That's always been the case, but later models are more sensitive. My 2013 model is very easy to control the stop/start

Yes absolutely, it is sensitive, but does work. 67 Plate DSG 1.4TSI

I've just seen that you can reverse the button on an Audi with VCDS so that when you start the car, Stop/Start is off by default and you have to turn it on. I know that doesn't fix the issue, but was interesting nonetheless. I wonder if it would work on the Octavia?

 

 

Not on a MK3 Octavia, the BCM is very different and there are no numbered adaption channels so 34 won't exist

Damn. I assumed they'd use a similar base for their modules. Oh well!

 

Thanks for the info

2016 tdi dsg. Agree it's a bit enthusiastic at times. I just turn the system off with the button when I know I want quick get away. At least the button is in convenient place! Eco mode gets even more "exciting" when it coasts and stop start kicks in. 

 

And don't get me started on being stationary for a while, hand brake on (highway code and all that), in P on dsg lever, engine stopped. Now we're off. ..Oh dear I'm not Lewis Hamilton am I.

No need to be in 'P' with the front wheels locked having gone through N and Reverse, if you can just be in 'N' and have stop start enabled or not and the Parking Brake on.

 

That is if you do not have 'Autohold' and you can stop in D with 'autohold' functioning. Stop / start on or not.   No need to go to 'N'. or 'P'.

 

Remember that some cars held with 'Autohold' have the brake lights on and some do not.

mine does the same and ive got the 2 liter diesel. The only way i i can get round it is to brake and have a bit of pressure on the throttle at the same time,
