Anyone seen this? I was driving through Chester yesterday in light traffic, eco mode on (sometimes it's what I want - don't hate me), pulled away from lights (stop start worked), then as I eased off the gas the car went into coasting mode (mine is a DSG), when I tried to build speed again the engine was off (I hadn't noticed it turn off) and up popped the "start car manually" or words to that effect. I couldn't turn the key as the maxidot was telling me to go into 'P' which I couldn't do on the move! So I had to brake to a complete halt, go into P then start the car again.

 

Most unnerving. Note, this is slightly different to the other eco mode oddities posted here where the box won't go back into gear and you have to either brake or manually change gear.

I've heard of this a few times on here usually when the car battery is too low therefore, the stop/start disables.  Was it cold this morning ?, lots of electrical load, not many revs (thats eco mode for you).

It was yesterday afternoon, mild. The thing is, I'd got the car running and was coasting in eco mode coming to lights, lights went green, I put accelerator down but nothing happened as the engine was off.

 

No significant electrical load. Looks it might have stalled, which is odd, I've never managed to stall a DSG car - especially when I'm moving at about 25mph!

Don't really understand the SS function if I'm honest. All I know it saves me money with lower pollution tax.

Sadly no pictures but you should get the idea...

The same happened to me several times all in Eco mode.

It seems that the ECU has a time out after the car was coasted or stopped for a while, it then requires a restart I presumed?

Furthermore even it was not stopped after a coast, the DSG was struggled to get back in gear.

I have since switched back to normal, having gear engaged all the time. I observed no different to my mpg so far.

In a manual transmission vehicle, stop-start is activated as follows: Stop car & depress clutch - move gear lever to neutral - release clutch - then the engine stops. The engine won't stop if the car is moving, even if the aforementioned steps are followed. The engine restarts when the clutch is depressed prior to selecting a gear to move the car

 

So with engine stopping it's a complete stop in the same way as if you switched off the motor with the ignition key and requires a cold restart? Does't it wear out the starter motor? Is it the equivalent to automating the process of switching off and on the car yourself or am I missing something?

Quite clearly Skoda have some bugs with Eco mode on DSG equipped cars. They should release a press broadcast advising DSG drivers not to use Eco mode until a full fix has been identified and applied. This could be quite a dangerous flaw.

It's the same system on the works Sharan. The system only likes a restart from stationary. If you're coasting it thinks you've stalled and gives you this error message.

If the engine has stopped then if battery is getting low or temps dropping it'll restart itself.

Do a test and see if Eco mode really does give you better economy. If it doesn't or it's marginal, maybe then it's just not worth dealing with the system's idiosyncrasies and use Normal instead.

 

The coasting issue and now this makes for a not so user friendly system.

I guess it's only a matter of time before someone gets rear ended.

When the traffic lights change to green and they suddenly stop.

But that'll be the person behinds fault

On the manual, if you stall the engine, the stop/start system automatically re-starts the car as long as you keep your foot on the clutch, so defo sounds like the dsg has a software error!

If you open seat belt for a period of time OR open door during Auto Stop then you have re start with key.

My car has also done this, in eco mode with DSG box, as I was going down a incline in a side street so was only doing about 15mph it was 8.50am and by a primary school, the car freewheeled down the slope and cut out, braked to a stop then the car restarted its self when I took my foot of the brake.

At traffic lights you have to be ready to take your foot of the brake a 2 or 3 seconds before you what to move of so that the starter motor can cut in.

Really? Seems he DSG doesn't work great with stop start..... On my manually by the time the clutch pedal hits the floor the engine is running and ready to go.

This is definately an issue (most likely software/calibration).

Stop/Start should not switch off the engine unless the vehicle speed is very close to 0kph (same for manual or DSG).

An automatic transmission should never stall when the vehicle is moving.

 

With a manual transmissions & Stop/Start, most manufacturers have a "stall" recovery system where pressing the clutch down fully after stalling will trigger an automatic restart. (as stated above)

I'm not sure if the VAG DSG transmission has a similar system but I'm guesing from the original problem the answer is no..

Not the case on mine, when I lift my foot off the brake the engine will have started before I can get my foot over the accelerator. Different engines mind you, between me and Colin1961.

Seems to be an issue with the diesel DGS's and not the petrol, not sure if this is something to do with the diesel starting process, do they still need to check engine temp. regards glow plug use or this that all old school nowdays.

I have a DSG Diesel, and to be honest, I hate the stop start most of the time.

 

It is fine when you are sitting at a set of lights, but the reason I drive a DSG is I sit in a lot of traffic, and if you are stop start (5-10 seconds) the car can keep switching on and off etc.

 

I started off using eco mode, but gave up after a few weeks as I convinced myself that if the revs dropped, I had to press the pedal harder to get the car working again, and that meant more fuel. Now, I have a fuel card from my company so not as bothered.

 

I love it on my wifes citigo as you have to consciously make it stop (putting into neutral etc).

But you have to consciously make it stop on the DSG too, by pressing the brake pedal further.

I've not had this problem with my TSI DSG, although for a while now I have been running in normal mode as I prefer the throttle response.

not really. often just having the same pressure I have had all the way to stop is enough.

 

Just wish I could switch it off and that it stayed off until I wanted it again. (no matter how many times I start the car)

Odd, I find it is easy to control the SS on a diesel DSG, and don't have any of the 'coasting' issues that others have in Eco. Not that I use Eco very often though, I prefer the Individual setting with everything set the same as Normal apart from the AFS which is in Sport to get the maximum swivel on corners 

 

All these issues with Eco & coasting seem to be on CR184 vRS DSG, I haven't seen a report of the same behaviour from us lowly CR150 DSG owners.

Just use the override button on the dash to disable stop start.
