I noticed tonight if you start turning the steering wheel the engine starts up again!

On the few times I have had stop start enabled I have caught it, ie stopped it stopping, by applying a steering input.

 

Still not sure if I like it

Also when pressing the break pedal, press it a little more down / harder - the engine starts up again.

To disable S&S just unplug the 2-wire connector on the negative terminal of battery. Result of this is an error in infotainment S&S status screen saying that the voltage consumption is to high. The regenerative braking system is also disabled with this mod, but then you do not need it since the S&S is not working anyway. There is however an error of "No communication to module" in the DTC Gateway module via OBD2 cable, but no EPC or MIL lights are present.

 

I hated the stop start system from the beginning, since I could not disable it via Obdeleven, the hardware route was taken.

The DSG Mechatronics pressure pump is only electrically driven and has no connection to engine running or not.

I've just got into the habit of switching it off when I start the car. I will switch it manually when in traffic etc.

It can be switched off in VCDS by adjusting the trigger voltage

Just takes a bit of getting used to.  Works fine for me.

There is definitely an issue with the DSG and stop start. It tends to cut it at the bottom of my drive just before I turn in. A yank on the wheel starts the engine again but it is annoying when you suddenly have no power steering just when you need it.

Autocorrect, again!!!

It’s a safety issue for me, having had (as just one example) the engine cutting out with no control at a pedestrian crossing!  Switching off S/S is now something I do every time I get into the car along with putting on my seat belt.

^^^?

No control of what, the car,

no brakes,

no steering,

no starting with a touch of the accelerator without moving?

I’m baffled by people apparently having so many issues with stop-start and DSG. Not perfect, but haven’t had any horror stories in 3 years and unless there’s a spate of system failures out there I can’t see why it should be such a struggle. I’m a very average driver but it seems straightforward to use.

“No control” is obviously a bit extreme, but it is true that the Start /Stop System does have a tendency to cut the engine whilst the car is still moving at perhaps 2mph and not slowing rapidly, and with the engine cut comes a stiffening of the steering, you can feel it give a very slight jerk. It is obtrusive, rather than dangerous IMO. But it seems poor design to have software that stops the engine whilst the car is still moving and the brake only being feathered. Especially when it only does that occasionally, certainly not every time. It seems more keen to do it when the engine is cool / shortly after starting a journey.

Yes can happen, you touch the accelerator and the engine starts, you then reach for the stop / start button and press it, 

or whack up the heating or put on the A/C that inhibits the S/S.   all part of driving.

It is like switching on wipers, lights, heated rear screen or switching off the radio, so many things that a driver can control and use on journeys.

Yes you can turn it off, as I mentioned earlier. But that doesn’t get us away from the fact that it is poor design to have a SS system that stops the engine while the car is creeping forward eg at a give way /roundabout. And for it to seem inconsistent in its behaviour.

Does it do it as you are creeping forward and not just as you wheel to a halt?

Very consistent in my experience of driving various models with stop / start and DSG, and as soon as you know when it is likely to happen you just think, 

best disable that.  It is not really rocket science, or flying a helicopter difficult.

It is a poor design and I hate it with a passion. 

 

On a number of occasions when I forgot to switch it off, the engine cut out just as I was about to pull out at a junction. It is dangerous IMHO.

 

I now don't have to remember to switch it off, as I have disabled it with OBDeleven.

Flying a helicopter is easy, but it would be unfortunate if the rotors stopped just before you landed!

 

It definitely does it as you are creeping forward and not intending to stop. But only occasionally! As you have said earlier, software is black and white, doesn’t have moods, but clearly there are some non-obvious parameters used in the algorithm that make it SEEM to be moody!

I tend to think that the engine stopping before the car comes to a complete stop as being standard - my last car which was a honda did it the same and another car I drove recently - which was a Ford I think also did exactly the same - all stopping the engine at about 2mph. Personally I am not a fan of stop/start systems so turn it of 99% of the time anyway. I am not sure why they do this - perhaps it helps an extra fraction with the emission categories when tested?

 

I did like the helicopter analogy above!

I might ask the dealer to turn it tomorrow if that's possible then.

Traffic Sign Recognition is my next gripe, it's right/wrong 50% most of the time.

Your traffic sign recognition is at least twice as good as mine then

 

Never seen it work once in 2k miles / 2 weeks of driving... what is it supposed to do? How would I know if it ever did decide to work (was under the impression it recognised speed restrictions / variable speed limits etc..)

That is what it does. It recognises signs but also uses the info from sat nav. If it sees a sign with a different speed limit to the sat nav it will display that. It also shows some other signs too - read the manual.

 

So on a motorway in roadworks with 50mph limit, it will show 50mph. Set the warning and it will warn in the maxi-dot you are speeding.

 

If yours is not working, then maybe you don't have it? Take a trip to the dealers.

 

It will never be 100% accurate. On some of my local journeys it will see a 20mph side road limit and assume it applies because the sign is at an angle. But it's still useful. You can ignore the false speeds.

Dealer told me it has / had it... never adjusted a speed recognition for me though.

 

In the settings menu (I've looked through the options in the vehicle settings and cannot see anything), what would it be under? Wondering if its been selected as "off"

 

I joined the forum to share / gain knowledge & experiences; reading the manual is both boring & defeatist

If set up correctly it will show the normal speed limit contained within the GPS database, but a temporary speed limit picked up by the camera will override this. I find it generally works, but does sometimes miss small or non-standard signs, and can falsely pick up side road signs or such as 20mph limit “when lights are flashing” when the lights aren’t flashing . It also shows “no overtaking” signs. Well that’s what mine does, anyway!

It sees signs from all the roads that you are not on, I went under a bridge the other day on the motorway, 30 sign pops up and says I am over speed limit. It sees tempary 20mph signs and displays them, it's rubbish and not fit for purpose.

If something only works about half the time what use is it?

If you get it coded all well and Good but if you have purchased it, I believe you and I have been robbed.

Mine picks the sign up on the left at the junction attached.

 In that example it's probable the permanent 20 sign is in the GPS database and its context of being on another road so good software should be able to recognise it as a false positive. Hopefully the software can and will be improved and updates made available (free).

mine cuts out when i'm creeping very slowly over a pointy annoying speed-bump!!!  i'm not even stopped for crying out loud!!!

piece of **** start-stop.

 

i've driven other cars with start-stop and i've never come across one that is as trigger happy as this one in the Superb.

 

so my start up routine everytime now is ignition on, start-stoff off - without fail.

The lack of control (on brakes and steering) is momentarily but that few seconds is enough to make it dangerous.  The specific example I was referring to is where I am about to come to a halt, then the engine cuts out before the car physically stops, leaving the car rolling.  You immediately re-start the engine with the throttle but there is a slight delay with that process as well so in that space of time you have rolled forward by at least a metre or two or possibly more which can make all the difference when you're in a very built-up area.  I had the system on a manual SII and it was never an issue and worked well, its just on the SIII that it is overly eager.
