I would like to hear of your experiences of Cruise Control in conjunction with the DSG gearbox, especially how it performs on hills, up and down.

(If there is a thread dealing with this I couldn't find it. Apologies if its a duplicate. )

It works fine on our 2.0 TDi DSG, changing down as appropriate - but I hate the feeling of not being in control.

Also I feel (but cannot prove) that a sensitive driver will get better mpg by subtly adjusting the throttle to ease off on inclines and make the most of declines to gain speed, whereas the cruise control will just batter on regardless...

It also works like a charm on our 1.9 TDi DSG. I use cruise control all the time on highways (well, atleast when the roads aren't too icy).

Increasing and decreasing speed with the cruise control switch is too jumpy for me, though. But I've sorted that out by using the accelerator pedal instead of my fingertips for getting more speed. Then again, this should have nothing to do with DSG.

Thanks for the replies.

I was hoping for a few more so I would have a better idea of how best to use CC in combination with the DSG, but perhaps the combination is not that common on this forum.

Does anybody know what proportion of Octavia II owners have the 1.9 or 2.0 L DSG compared with all the petrol and diesel manual versions?

Just to add my 10 cents worth, I also have the 1.9 tdi and regularly use cc and dsg. Performance is great -- the engine torque is usually sufficient to get up hills without the car changing down, but even when it does, the changes are pretty much imperceptible. I haven't really noticed it on downhills as there aren't that many on my daily commute. On one stretch in a 50km zone, I sometimes get the impression that the car is braking to hold speed -- maybe someone else can confirm? On the open road, on steep hills, I've always preferred to knock the box over into manual mode anyway.

I have both on my 2.0TDI estate and I can tell you it it works very well coming to its fore on those long French roads where you can often sit there for an hour or more and just merely steer the vehicle.

I use it here in the UK traffic conditions permitting, not always easy, but I find it OK on country roads and those straighter villages where the Feds lurk with their speed traps.

It is very easy to regulate your speed using the rocker switch on the stalk, but the speed increase is not as smooth as using the accelerator pedal. You also need to be careful using the rocker switch to reduce speed as the weight of the vehicle or slight slopes tends to keep the vehicle rolling at close to the original speed for many yards.

That said it is a very good piece of kit and that DSG box I really rate as excellent, but if you are the slightest heavy footed it shifts down and pushes you back into the seat. A problem in speed trap areas if not aware of the power you have on tap.

I have the 2.0 with the DSG, I use the cc a lot, it seems to work very well on hills and is great for avoiding speed cameras, I dont find changing speed with the stalk controls too jumpy. This weekend I used the stalk to take it from 40k's to 160 and it was a very smooth way of accelerating as the engine/geabox knows better than I!

Agreed: a very smooth combination, and very precise to control increases/decreases in speed with the CC: DSG box just gets on with it: totally unobtrusive and VERY capable in auto mode:thumbup: this is on a (Jabba-mapped) 2.0 TDi Elegance Hatchback with DSG & CC.

First, thanks for your replies.

Thanks to VRS_Stu I can confirm that Cruise Control and the DSG gearbox work very well together, and even on moderate down hill sections the speed only rises by a couple of miles per hour above the setting. So in speed camera zones it would semm sensible to set the CC just under the speed limit. That and the optimistic speedo reading might be enough safety margin.

I haven't tried it on a really steep hill, but there must be a limit to engine braking even with the diesel.

So far, so good. I'm glad I went for the CC option.

That's an interesting point - does the box change up to increase engine braking in a situation like that? One criticism of CC on my Mondeo is that it only uses engine braking to slow down so on steep hills, the speed will start to increase, especially when in 4th or 5th.....

I think if the DSG changes down it will drop out of CC.

Hi all,

The DSG changing gear did not disengage the Cruise Control as far as I could tell, but I will carry out more systematic testing on quiet roads without the wife on board and let you know the result.

Only engine braking appeared to be available, and as far as I know there is no connection between the CC and brakes. Haven't tried it down a steep hill yet.

The throttle closes down, but if the hill downgrade is steep enough it does tend to gather speed. However, when the throttle closes there is a degree of engine braking on small downgrades.

This is fine when using CC on long open roads like those you find in France and parts of the Continent, but our short roads and speed cameras in the UK it is a problem you have to be aware. Also remember the merest touch of the brakes disengages the CC.

DSG changing gear definatley does not disingage the CC. On a incline it will drop a gear to maintain the speed/momentum

That's good to know then.
