Rolling back on hills when Drive engaged - do they all do this?

[PGW]

Hello,

I have a 2014 Superb Elegance 170BHP 4x4 DSG and am concerned with it rolling back.

After stopping on a hill the auto stop start will cut the engine, when I ease the pressure on the brake pedal the engine starts but between the time when my foot comes off the brake pedal and goes onto the accelerator the car rolls back.

I demonstrated to a Skoda mechanic at my dealership: I stopped on a hill, the engine cut out, I took my foot off the brake, the engine started, I deliberately didn't touch the accelerator and while the car was still in Drive it rolled back over 2 metres!

The dealer is telling me; they all do that / the DSG gearbox isn't really an auto box like other cars (Mercedes) / the extra weight of the 4x4 causes it / they can't do anything about it...

It just seems wrong to me.  Has anyone else experienced this?

All responses gratefully received - thank you.

Not having a DSG myself...

...but I suspect this is normal behaviour and what the hill hold control was designed to resolve

VCDS might be able to enable that for you depending on what ABS module is fitted to your car

[StuartTunstall]

They are correct I think, the DSG is not the same as an Automatic gearbox, it is an "electronically controlled manual gearbox" 

 

I have done hill starts in mine, all I do is lift the foot very slightly, the car will start but I still have the brakes on.... when needed I move from the brake to the accelerator and move forward... I think that you may lift you foot too far off the brake, this then causes the hill hold to disengage, try just lifting the pressure off the brake, if like mine it should be enough to restart, but still keep the brakes on..

 

your comment, "I took my foot off the brake, engine started and I did not touch the accelerator.." Hill hold only hold the brakes for a few seconds, not until you are ready

Handbrake?

[StuartTunstall]

This is what the owners manual states... 

 

Hill Hold Control (HHC)

Read and observe and on page 151 first.

When driving on slopes, HHC allows you to move your foot from the brake pedal

to the accelerator pedal without having to use the handbrake.

The system holds the brake pressure produced by the activation of the brake

pedal for approx. 2 seconds after the brake pedal is released.

The brake pressure drops gradually the more you operate the accelerator pedal.

If the vehicle does not start off within 2 seconds, it starts to roll back.

The HHC is active on slops of >5 % if the driver door is closed. HHC is only ever

active on slopes when in forward or reverse start off. When driving downhill, it

is inactive.

Maybe you don't have 'Hill Hold', it was a cost option, £170 which included tyre pressure monitor or for those with tyre pressure monitor as standard (Elegance and L&K) it was £115. Without this it will roll backwards.

 

The brochure claims only 1.8 and 3.6 petrol DSG models have it as standard but there is another older thread on here that claims Skoda made a mistake in the brochure and none have Hill Hold as standard, and that it was an option on all models. I have the FL brochure with me which is where I have the prices from.

Even with hill hold you will find you need to use the handbrake at times. Its just one of the quirks of DSG. It catches me out every so often, like last night trying to reverse up a hill while doing a 3 point turn, the car rolled forward a few metres before I caught it.

Yes they all do this unless you have the optional Hill Hold . I think this option should be standard, but it isn't.

The way I overcome this issue is to restart the engine, whilst still having my foot on the brake. This can be done by either switching off the Stop/start system for a moment, or as I do by  just touching the accelerator pedal.

 

I find this works and there is very little, if any, roll back.

 

A small fault with a great gearbox.

PGW, I have your car in L&K. I have moved from a torque converter automatic in a Volvo to the DSG and I had EXACTLY the same experience.

The first time I started on a hill with the STOP-START engaged I just thought oh-no. The next time someone was quite close behind me and it scared the S... out of me.

 

I changed the hill-hold control setting in the cars computer. You can buy a Can-lead to connect or find someone friendly nearby who has got one. The dealer will charge you unless they are very friendly....

 

Go into Mod 03 ABS Breaks

Adaptation - 10

I think it was Channel 36

Now you have 3 options. Mine was set to =0 (Values can be 0, 1 or 2 ) - 1 I think is low revs and 2 is high revs to disengage.

I changed it to 2 and there is no more rolling back on slopes.

 

All it does is to activate the brakes via the brake/ABS module until you are ready to drive off, kind of a electronically activated hand brake.

 

The hill hold is in the options part of a Superb and it is a cost option...

I don't think its anything to do with the "type" of gearbox. We have an auto Vauxhall which is also a electronically controlled manual, with a single clutch arrangement and that doesn't roll back at all on hills, much like the older torque converter type gearbox.

 

Although I don't have hill hold, seems to be a characteristic of the DSG. Does the same thing when reversing on a hill, will roll forward a metre or so before it "bites". There is a technique to reversing and hill starts without rolling back, takes a bit of practise and sometimes use of handbrake is necessary.

That happened to me on the test drive, I opted for a manual after that

Thanks for all the useful comments and suggestions regarding my original question.  

From the sensible people I learned about the Hill Hold feature, this is the solution.

My car did not have this, that was the reason for it rolling back.  I exchanged cars with the dealer for one which had Hill Hold - the replacement one is absolutely perfect.  If the engine stop start function is activated the car will hold itself on a hill long enough to accelerate and drive away.  It is just as I expected it to work, and similar to automatic cars with the normal torque converter type gearbox, so the handbrake is not necessary.

If anyone wants to buy a DSG Skoda Superb I would definately advise to get one with Hiil Hold, in my opinion it is a 'must have' option.    

Thanks to Andrew Pengelley at Specialist Car Skoda Aberdeen for allowing me to exchange the car I bought, and sourcing a similar spec model for me with the addition of Hill Hold.  Great customer service, recommended as a dealer.

That really is great service - well done them!
