I have now had several occasions where the auto Stop/Start system has cut the engine whilst the car is still rolling slightly, no brakes on, and the auto-brake disengaged.

The engine has then thought better of it and restarted immediately. This 'opportunity' has also meant the steering jerking suddenly too. I assume the steering must be electro-hydraulic so the loss of the engine cuts the power assist as well.

It is worse in 'Eco' mode - a mode which despite its name, actually has worse fuel economy than 'Normal' mode.

Anyone else had this?

Had this today when I had forgotten to turn it off... Leaving an ncp. Just pulling upto the barrier and the engine stopped before the car !

My fault for not turning the bloody thing off. The engine was also clock cold.

I need to improve my startup cockpit scan ...

Might be worth looking into a VCDS tweak to have the Stop/Start permanently disabled when you first turn the ignition off - essentially making you now need to turn it on. As opposed to remembering to turn it off

What do we think initiates the engine turn-off?

Surely if its doing so BEFORE the car has stopped, its not working right?

Is this DSG or manual?

DSG for me Drew

DSG for me too. And no it should not activate (IMHO) unless the wheel speeds are sensed as zero.

Dealer is now aware and it will be looked at during the one month 'free safety check' - and oil change (I'm old fashioned) as I will have done just over 1,000 miles by then.

Wow. That's pretty nuts for a DSG. I've had it happen once or twice in Eco mode with the air con off and coasting down to a stop but I'm usually a wheel rotation away from stopping. It certainly does it on manuals a lot more when you've coming in to stop.

That was in a 150 DSG MkIII Octavia above

The Insignia I had the other week would switch off when rolling up to traffic lights.

Would also start/stop at the beginning of a journey but then 30 mins later wouldn't.

In my new Octavia it will stop if you coast to the lights if out of gear. If you try to steer it will start back up.

If you read the manual that is correct operation.

Wonder if the dealer can default this to off? Anyone know? Or is it def a VCDS only thing?

My wife's Ford Mondeo (latest, 240PS petrol) has this and what I really hate is it'll activate if you come to a stop on the motorway. After an hour of...er...70 mph (officer) driving. This is not the way you treat a red hot turbo for long life.

Surely dealerships (and authorised repair centres) would have access to the same things as VCDS?

Maybe there's a separate cooling pump for the turbo?

 

When I park-up after a trip I can hear something running after the engine is switched off.

 

Thunks, you live in Essex & have a new petrol Mondeo in your fleet, does someone in your family work for Ford?

 

We are both Ford pensioners & "should " still be driving Ford's but have somehow been lured into Skoda Ownership!. 

We did have a test-drive in a new Superb 3 yesterday, from Essex Ford / Skoda in Rayleigh & it must be tad smaller than the Mk5 Mondy,

'cos it fitted into our garage.....

Well guessed DC. The wife works at Ford! Her second company car goes to her family as I just get bored with them. The new Mondeo is a beautiful and well put together car but I want something different. Am totally in love with the new Superb and currently working out when and what I'll buy. Very inspired by Nick H's choice of 280PS in red with modulus alloys though I'd get the hatch. Do you think you'll invest yourself?

I noticed this in a manual Superb III I drove. Kept cutting in as the car was rolling. Very annoying and unsettling!

Also highlights poor driving techniques, people coasting too much.

You should be in a low gear and then declutch as you brake and stop.

The fuel saving and environmental benefits outweigh the negatives.

Mine also seems keen. I had a manual golf previously and that was fine as I felt in control as I had to put in neutral for stop/start to activate. In my DSG superb it seems to do it at the drop of a hat! In queues it's doing it every few seconds. I would've thought a timer would help eg only stops if you've been stopped for say 3 secs.

It would be good if you'd be kind enough to post back the dealer outcome and whether this is just a 'feature'.

Following on from this, can someone please remind me/clarify again how stop/start works on a DSG Box? I think I read somewhere that you have to press the brake pedal softly to stop it from engaging the stop/start system - and that a firmer press of the brake engages the stop/start and the engine will then shut off?

Do you mean using auto stop Dilz or just generally with DSG ?

Although I'm on a new Octy3 DSG (MY16) I have found this too. I did a long test drive in an older Octy (MY15) and did not have the same problem.

 

On mine it is almost impossible to stop the car with a brake pedal light enough to beat the S/S in most situations. If you are uphill then you sometimes get it to work. 

 

I have not yet been able to brake to a stop and release the brake pressure enough before it cuts out. 

 

It may only be my perception but I do feel it cuts while still in motion

Invest? 

In a new car?

In a depreciating asset?

 

I might just be tempted to throw my hard-earned savings into another car soon though, & SWMBO does like the Superb 3.

 

Problem is, we both still like my Superb as well, & I'm not allowed to even contemplate selling the EOS ......

 

Perhaps I can persuade her that at her time of life she should trade up from her Octavia RS into my sensible Superb, & let me

use her Octy as a trade-in against a superb 3?

 

It would have to be an estate 'cos there's no sense in owning 2 hatchbacks & since the 220 ps car that we drove seemed a little bit flat

compared to our existing cars, then we'd have to follow Nick's example & go for the 280ps instead.  

 

It doesn't help that she likes the L&K over the SE-L.......

 

Short answer, I probably will but I'd like to save some pennies if I can find an ex Skoda Management car early next year.

 

It's what I'm driving now, & like my last two MRC Mondeo's, they are often good value for money.

 

HTH, DC.

 

 

PS We both wanted to love the new Mondeo, but we can't, we would with you agree that it's a good car but it's not just as chuckable as

the MK's 1-3, & even bigger than the MK4.

I parked my last MK3 Estate along-side a late Scorpio & it was dwarfed by my old Mondeo!  

Dont know about the Skoda yet but in the merc the stop/start with a dsg box does what it says on the tin. Brake to a stop and the engine will stop, take your foot from the brake and it starts. You cant use the pedal softly. If you want to end up with the equivalent of handbrake on then once stopped, without removing the pressure on the footbrake pedal, I have to push a little harder and this engages the holding brake and the notification light shows in the dash. As soon as I get anywhere near the accelerator, the lightest touch, and the engine starts and we move off as the holding brake disengages automatically.

 

Remember that the system will usually always stop the engine but it may restart after variable times if the power drain (a/c on. lights on, heated seats etc) is high. Also in traffic I find that it will work for a while then will not due I think to the power drain again.

 

My issue with the merc is that unless you have triggered the holding brake and inadvertently lift your foot from the brake hey presto the engine starts and you move forward. A bit non plussed when that happened the first time   Rather boringly I mention that my advanced driving instructor shouted at me so many times about stopping behind the vehicle in front so that you can see their rear wheels touching the road. That, of course, meant I didnt dent the car in front. He knew I would need that trick one day :clap:

 

Like all these 'driver assist' systems I think it is a case of getting used to how they work and using them. I remember the first time I used cruise control; took a while to become confident in that but now I wouldn't be without it.

 

p.s It will keep stopping and starting in traffic, that is what it is designed to do!

You read correctly. Gentle braking to a standstill will engage auto-hold [if enabled] but not start-stop.

I've only had the car 2 days but I've quickly adapted to "normal" braking a few feet earlier on approach to roundabouts or open-view junctions but easing off [not fully releasing] the brake pedal pressure on final approach.

It means I can proceed smartly if it's safe to do so, or otherwise come to a complete stop without stop-start engaging.

If the car is stationary for a short period [not timed it but feels like between 5 to 10 seconds] then the start-stop system will activate and stop the engine, which IMHO is ideal as it prevents any excess straining on the gear box.

 

The same applies if I intend reversing into a driveway, parking bay, performing a three-point turn, etc.

PITA if you brake normally: engine stops - engage reverse - engine restarts.

So rather than brake normally from forward motion, invoking the start-stop, I ease it to a gentle stop and then engage reverse without the engine stopping/restarting.

 

You could get the same results by pressing the start-stop button beforehand, but I prefer to adapt my driving to the vehicle characteristics rather than vice-versa.

 

On a side-topic, I don't like the brake lights remaining illuminated with auto-hold for any extended period (especially at night).

I've got into the habit that if I'm stationary for more than a few seconds and there is traffic behind me I simply flick on the electronic handbrake and dab the footbrake.

This results in the vehicle still holding but without the rear brakes remaining illuminated.

Wonder if the dealer can default this to off? Anyone know?

They won't.
