The 'A' button / Stop Start Issue.

Featured Replies

I'm sure this is in the manual somewhere, but I can't find mine at the moment.

 

I've got a DSG 190 4x4

 

There's the 'A' button for turning off the Stop/Start, but a little to the left there's another 'A' button. What does it do?

 

Also, stop start - is anyone else finding it's a bit too keen? In slow moving traffic it's stopping and starting constantly, and it'll often cut out before I've completely stopped, meaning just occasionally I'm losing power steering just when I want to move around a parked car or something. I quite like it as a feature, but it just needs to chill out a bit.  

I would think it's your auto hold function. 

 

I can't stand the Start/Stop and deactivate it every time I get in the car.

Yep - sounds like Auto Hold.  Love the feature - and much handier than the one I had in the Insignia.

 

I too disable Stop/Start as soon as I fire the big-barge up - drives me nuts.  I know, I know, it's there to help us save the planet etc., but I always worry that, once it's stopped, it won't start again.  That and the slight delay for the engine to start when pulling away drives me nuts.

Thanks Both,

 

I think I'll preserve with the stop-start. The auto-hold does actually sound useful. I had no idea!

 

I'm still trying to get my head around my new car, it seems very digital compared to my old manual Exeo. Sometimes it's very 'surprise and delight' and sometimes it seems pointless complex, depending on my mood at the time. 

 

My Wife doesn't like change and I was giving her the low down on it before she uses it. Between the various buttons and basic 'driving an auto' stuff she started to think a lot of the convince stuff made it more of a faf.

 

BTW, I've been told if I dislike the Stop /Start you can have re-coded (by the sort of place that does remapping) to not only default to being off, but so the alert on the dash tells you when you turn it on, not a warning that it's off.

The stop start we had on the Vans in work was better, there was a bit of a pause before it stopped so it didn't cut so much. I'd guess ours was made for emissions tests more than emissions per-se, the fact it happens pretty much from stone cold and when you're still moving slightly is very annoying. 

You know you can permanently disable the Start/Stop function by using an OBD II adapter such as the Carista, and it's all pretty cheap (around 25 pounds and it will activate/deactivate a number of other customisable features on the Superb III).

Wonder when I'll need a new starter motor ?

Hi, I am considering the Superb but with the price rise I'm also looking at other options including the Insignia estate. We have a Karoq so very used to auto hold and it's something I'd like again, could you explain the issue with the Insignia please?

I bought a Carista dongle to use on my last car - 2015 VW Touareg.  I used it to program start/stop to remember "last state", rather than default to enabled each time the ignition was turned on.  I don't think it will work with a Superb though. When I checked a couple of months ago, it wasn't a supported function.

 

I did make an interesting discovery about start/stop a few days ago though. In traffic, with start/stop enabled, the engine doesn't switch off if I am very gentle with the brake pedal. Roll to a stop with very light braking (just enough to overcome the "creep" of the DSG), and the engine will stay running. If I can see that I will be stationary for more than a few seconds, pressing the brake pedal a little bit harder will stop the engine. 2016 L&K 280 estate.

Trouble is the clutches are lightly engaged in that scenario which will wear them.

Auto-hold: Useful, I use it nearly all the time. Its setting (on or off) is “remembered” when the car is shut down and subsequently started.

 

Auto stop start: mostly a pain. Far too keen to cut in even whilst the car is moving forwards at a couple of mph. Its setting (on or off) is NOT remembered. It is always on after start. I generally turn it off after start but if I can see that I’ll be stopped for a while (eg lights just gone red) I’ll prod the button to activate it and the engine then stops until I press the throttle.

The Carista being able to disable the start/stop function absolutely does work. Did it on my Superb on the first day I got it (couple of months ago) and has worked faultlessly ever since.

Can Carista reprogram stop/start to remember the last state selected by the driver? That's how I did it on my Touareg - I left it switched off for normal driving, just engaging it in bad traffic. If I was driving with it switched off, it would stay switched off the next time I drove the car. I wonder if Carista can only permanently disable stop/start on the Superb? Maybe I'm getting confused by that. I did look into it a few months ago, and I'm pretty sure it wouldn't do exactly what I wanted.

 

I'd try it myself, but I only signed up for the free 1 month trial. After setting up the Touareg, I gave it to a friend, and he gave it to someone else because it would do much with his BMW.

Is that any different to switching stop/start off, and holding the car on the brake in drive? Does pressing the brake pedal harder fully disengage the clutches?

 

I've had a few automatics, and have always done that - unless I know I'll be stationary for more than a couple of minutes, when I'll put it in neutral, or in park and switch off.

There are two options for disabling start/stop on the Carista available for the Superb. I selected the first one and it's worked fine (I didn't try the second one). The start/stop always stays switched off no matter what. 

I don't get why start/stop bothers some people so much. Useful when you know you're stopping for a while at lights etc. Is it really that troublesome to push a button if you want it off? Doesn't have to be done when you first get in the car, just do it when the first 'stop' happens. 

I wonder how many people who hate stop/start drive diesels, where the starting and stopping is really obvious?

 

On my TSI220 the engine is quiet at idle and starts and stops with barely a judder, unlike the diesels. Also with DSG (and autobrake off, which I never use) it restarts when you take your foot off the brake so it's running by the time you press the accelerator, I don't see any noticeable extra delay compared to having stop/start disabled.

 

WIth autobrake on it stays stopped (with the handbrake on) until you press the accelerator, which *does* give a nasty delay.

 

And as was pointed out, even with stop/start on you can keep the engine running by braking gently -- and if it does stop, a tweak on the steering wheel will restart it.

 

Don't forget the real purpose of stop/start isn't really to save fuel (except on unrealistic test cycles like NEDC), it's to reduce pollution in hotspots from idling engines in stationary cars... 😉

All I can say is that I experimented by breaking gently to a halt without actuating the auto brake. The rpm was at 1000. I then prodded the brake to engage the autobrake and the revs went down to 800. I assume that as the revs dropped the system knew I didn't need drive so it makes sense to me that the system would also disengage the clutches as well, unless of course anyone who has inside info can enlighten me!

Stop start is irritating and not a little dangerous if you see a gap and want to nip out only to find a second or two delay as the engine restarts. I find only a little movement of the steering wheel will restart the engine, often do that to get it running as traffic lights change to amber.

I really don't get this "second or two delay", unless you have autobrake enabled. On my car (TSI220 DSG) with stop-start enabled (autobrake disabled) the engine restarts when you take your foot off the brake, by the time you get it onto the accelerator it's already running. Is anyone else's car different?

 

[autobrake on means a delay, engine doesn't restart until you press the accelerator -- but this is turned off by default and I never use it]

E.g. at a junction or roundabout (with poor sight lines) I'm approaching it slowly and the engine cuts out while I'm still moving because I'm not under throttle, no autohold as I'm not stationary; I see there is a gap I can slot into but, as the engine has stopped, there is no immediate response and the approaching vehicle is now much closer and I've already committed myself. Maybe exaggerating by saying 1 to 2 secs.

 

Mine is the newer 1.5tsi 7 speed dsg, I had the 1.4 tsi dsg Octavia before and the Superb is much smoother in the way the start stop operates.

I don't think I've never had that happen (TSI220 6-speed wet DSG); usually I'm slowing down under braking, if I lift foot off brake to pull away again (even if not stopped) engine restarts triggered by foot coming off brake, it's ready to go by time accelerator is pressed.

 

Maybe the dry clutch DSG on the 1.5TSI behaves differently?

Take back my earlier comment, am finding start/stop much more irritating with the dsg than the manual. Will be keeping off unless stuck in heavy traffic. 

For extra fun try towing with it. I learnt soon after purchase that s/s is not automatically disabled when towing. Cue scary moment when pulling onto busy roundabout only to find car is a few seconds behind brain and my car hasn't leapt gazelle-like into traffic but has just lurched into it. :o

I now prod the s/s when I get in and very occasionally use it at familiar traffic lights.

Crawling in rush hour traffic is a pain and 'it only cuts the engine with high brake pressure' is cobblers as that wouldn't allow it to stop the engine whilst the car is still moving.

It certainly seems to work that way in my car - brake with very light pressure on the pedal, engine keeps running. The car will come to a complete stop, engine still running. If I press the pedal harder once the car is stationary, the engine will stop. Useful in stop/start traffic at very low speeds.

 

I can get it to do the same at traffic lights and junctions - back off the brake once the car has slowed to walking pace and pull up with very light braking, engine stays running.

If I brake a bit harder, with the steering wheel straight ahead, engine will stop while the car is still moving.

 

I mostly drive with start/stop switched off, as I live in a fairly rural area. I just switch it on when I'm in town, or when I get stuck in a traffic jam.

 

I didn't notice this on my previous car (2015 Touareg), but that had a much torquier 3 litre diesel engine and a different gearbox, so probably needed harder braking to stop the car.
