Morning all. 

 

A question about the start stop and dsg. When the car restarts, half the time it will instantly pull away and half the time there will be a 2/3 second delay and requires the accelerator. It seems so random without a reason. 

 

Is there something wrong with it or is this normal? Is there any way to regulate the way it works?

 

thanks

 

on a hill?  have you touched the DSG selector?

Not on a hill - I'm in Cambridgeshire most of the time which is very flat. I leave the dsg selector in drive with my foot on the brake (no handbrake) 

 

It does not seem to change with different length stops   

The foot brake is very sensitive. Try turning OFF the start/stop and when you pull up at lights, with the foot brake "semi" depressed (i.e. enough to hold the car) you will see the revs at 1,000rpm. If you press the pedal harder, the revs drop off further. With the stop/start ON, the engine will start at the 1000rpm mark without pulling away. At least this is what I've found in my experience....

Stop start works really well in the manual's I have driven. Its really annoying in both my DSG cars. It spends far more time off than on.

Mine has been like this from day 1. I just took it as a "feature" of the DSG controllers.

 

I hate holding my foot on the break at lights etc and in my manual, I simply drop into neutral and pop the handbrake on.

 

I've not had much exposure to the DSG yet, but expecting one in the next month or so and this is something that has plagued my mind. 

 

Hopefully it'll not complain too much at being put into N and the handbrake on as often my manual does.

+1 I've noticed this too and also just put it down to DSG quirks. I've only had my car a couple of weeks and this is my first ever DSG so again nice to know its not just me finding these quirks.

 

I personally just ride the brake hard enough for stop start to chime in.. though I've noticed a slightly lighter touch will keep the engine going and the car stationary just fine but the dsg ready to go  this is better for short pauses in queues at junctions/roundabout I've found for me.

I did have my first real test yesterday, stopped mid way up a hill for roadworks traffic lights. Left it in D foot hard on the brake to hold it stop/start kills the engine. I engage the handbrake. When the light goes green surprisingly besides the slight delay restarting engine and then moving, the car actually held itself without the handbrake - so do they have hill hold too?

Yup - or at least the spec you have does.

Thanks, learning experience with DSG/Autos still - I've just owned/driven manuals predominately since passing my driving test 29 years ago last month (s*** it really is that long)   You always know where you are with a manual car as you're in full control always.

However it was time to change now living outside of London and now with a family time to chill out (99% of the time) hence the Octavia for practicality/comfort with kids. 

Not sure if I explained well enough. The start stop works great and the difference in pressure to activate it works well. The problem is that when lifting the brake pedal the car will start then do one of two things -

 

1. instantly pull away and start moving in 1st gear

2. stay stationary for 2/3 seconds before realising it is in gear and it pulling away and start moving.

 

Wondered if others were the same?

I know the feeling. I literally drive 4 miles once or twice during the week depending on the weather (I cycle normally) and then on the weekends/trips.

 

Decided that the lack of mileage I do and after breaking my foot a few months ago, an automatic was the way to go. I'm paranoid that I'll either do damage or end up rolling down a hill lol.

I've noticed the same too.. I think I was trying to say that in my first post!  A couple of us were effectively +1-ing you original post I've edited to make it clearer

Yes it’s a feature, mine is exactly the same

That's such a shame. I wish I knew what the car was going to do and when! thanks 

You get used to it in the end, you start to read the traffic in front of you and get ready to release the brake pedal in time for it to start up and work itself out.

Sounds very similar I don't commute with my car, I cycle to/from the nearest train station most days and head into London (not today as the trains were broken once again). My wife uses the car for local trips during the week, main driving is at the weekends. To be honest its not that much different for me to London car driving wise, except I used a motorbike daily all year round for 18 years to get into central London where I work from out East where we used to live. So I've retired from that now and my motorbike is having a nice sleep in the garage on a battery tender 

The stop/start is stupid.

 

I drove up to a right turn from main road (UK), with a moving line of cars so I thought let S/S kick in and I'll wait for half minute or so. But as soon as engine stopped, a car flashed his headlights. I ended up being flashed 3 times before my car is able move. Made me look like an inattentive slow numpty.

 

But you shouldn't disable S/S. In as little as 7 seconds it would have started saving you fuel compared to letting the engine idle.

 

 

Switch to all electric is the only way, all other methods are just a Band-Aid on the leaking damn known as fossil fuel engine tailpipe emissions.

In my cheaper commuter EV (60 miles commute, not a short distance to drive everyday), I'd have gone in that same situation before the car had finished flashing. Instant electric torque!  Having gotten used to the 110hp effortless, cheap to run EV, the 150hp turbo diesel feels sooooo slow, unresponsive, unrefined and expensive to run.

I find that if you 'blip' the brake pedal up and down it starts the engine back up again so you can still make use of the SS feature but can start it up before you need to pull away.  When the engine is running and you are stationary it pulls away much cleaner with none of the oops-start-oops-gear-oops-clutch lag. 

I also find that if you lift your foot off the brake and blip the gas pedal it jogs the system into thinking a bit faster.  Too much gas gives you a jolt so just a little blip before feeding the gas in again.

I kinda get used to it, if I'm slowing down but I see traffic ahead moving or if it's a junction where I need to get away in the next available gap I'll balance the brake pedal so it doesn't kick in.

 

It's a pain in stop start traffic though, don't think it's good for it or DSG, but traffics traffic not much you can do.

What about ACC and stationary traffic? e.g. I have it set to 30mph and the traffic in front stops?

Same with mine. Exactly as you describe sometimes it will start creeping after starting which means it will be a smoother pull away after the stop / start has happened.

 

Other times (randomly) it doesn't seem to wake up and will sit there without creeping. It is those times that if I pull away too quick I will get a bit of a jolt as the car realises I want drive and it engages the clutch abruptly.

 

Holding / feathering the brake pedal to prevent stop / start activating can be useful for a quick get away as others have described, though my concern is, is this allowing the clutch to slightly engage and as a result causing undue clutch wear?

 

I have got into the habit of pressing the disable start / stop button on junctions or lights that I know I will require a quick reaction from the car.

 

I like the start / stop idea but sometimes it needs to read the mind of the driver

Same here. And just as the OP describes. 

 

Sometimes smooth and effortless, sometimes embarrassingly jerky. My 2010 vRS DSG was soooo much better at slow speeds. 

I always disable stop/start as soon as I start up.  However, I also get these unpredictable starts, but only when in 'Sport' mode.  Never in Normal mode.

A DSG car is quite happy being slotted into neutral with the handbrake on.

 

If stopping for a few seconds I find it fine to simply keep a foot on the brake pedal, but I don’t like holding the brake lamps on for a long time. Especially in the dark.

 

The problem is if you get things wrong.  The handbrake won’t hold the car if you leave it in Drive. The clutch drags. So to avoid the clutch dragging, you either have to keep your foot firmly on the brake pedal so the clutch disengages (see revs drop) or select neutral.

 

The Hill Hold is almost a waste of space as you only get a 2 second pause before the clutch re-engages and the car wants to take off.

 

You’ll soon figure out what works for you.

 

ps - I was ecstatic to find that the Kodiaq has a proper Hill Hold auto brake - unlike any car I’ve driven including a Q5 - that simply keeps the brakes on with the clutch disengaged when you come to a stop. Then you simply press the GO pedal when it’s time to take off again. It’s absolutely fantastic and is how all cars should be in the 21st century.

 

pps - Stop / Start is just the spawn of the devil and should be switched OFF as soon as you start the car. All the problems mentioned above just go away.
