A up peeps. I'm either being totally thick or my CC isn't working as it should. Either way I could really do with some help.

Running a MKII FL Octy VRS and whilst giving it a run down the M6 I noticed if I knock it down to say 55-60 (was travelling at 70) it sometimes surges and pulls back up to what I'm assuming is 70. I know it can be set to remember but I was under the impression that's only the case if you cancelled it, then reactivate it the car would go back to it's predetermined speed.

An example would be where you have a random braker in front or approaching sudden traffic (M6 remember ha) so you just cancel and return to manual driving.

So why does it happen without me cancelling? The sudden boot caught me off guard. Surely it shouldn't behave in a way where it suddenly jumps back up from where you've just slowed it down. What am I doing wrong?

It should only go back to the set speed if you 'resume' which means physically pressing the switch on the stalk to 'resume'.  If you are on CC and brake, accelerate, cancel or turn cc off the speed should not increase again without you telling it to by pressing the resume.  Even if you accelerate after it will not go back to the set speed without being told to.  If it is doing it shouldn't be and as you rightly say it could catch you out which is why it shouldn't.

Hope that helps.

According to the manual for my car if Cruise Control is active and you accelerate and then take your foot off the accelerator the car will return to and hold the set speed.  This certainly happens in my car and is useful if a higher speed is required for just a few seconds to 'hurry up' an overtake.

 

From my manual, page 114 - "You can increase the speed by depressing the accelerator. Releasing the accelerator

will cause the speed to drop again to the set speed."

 

Otherwise I agree with all that you say.

Interesting, mine doesn't do that, touching the accelerator knocks off the CC, if I come off the accelerator the speed would drop all the way to zero if you let it.

 

The only way to get it to sit back at the set speed (without manually accelerating) would be to hit the resume button.

OK I will check that on mine (2010 VRS) next time I am in it which will maybe be Saturday but all other cars I have had have acted as I state although I have not tried it with mine but do not disagree with what you say.  For fullness I will check though and report back.  In any event it still should not accelerate back to speed on it's own.

That's weird.

 

I can floor the throttle (and even instigate a kickdown) then when I take my foot off the throttle it resumes the previous set speed.

 

The only time I need to press the resume button is if I've either braked or pressed the cancel button... Pressing resume from 30mph after having it set to 70mph is fun!

How are you 'knocking it down to 55-60'?

If you hold the lower rocker button in it will decrease the speed until you let go, then the car will carry on at that new speed.

If you are cancelling the CC using the three position switch on the top of the stalk then the car still retains the last set speed and will resume at that next time you activate it using the bottom of the toggle switch.

Pressing the top of the toggle switch activates CC at the current speed of travel irrespective of the last stored speed.

I hope I've explained that clearly!

Changing gear, touching the brakes or pushing the switch on top all cancel CC (but retain the stored speed ready for next activation).

Accelerating with the pedal does not cancel CC and the vehicle will slow down to the stored speed once the accelerator is released.

Another tip is a single press up or down increases/decreases the speed by 1mph at a time. Good for fine tuning the speed.

My almost identical 2008 Scout does not cancel the cc if the accelerator is used. I wonder if this is a setting somewhere or a difference in modules between the two cars?

Other than enabling\disabling CC I have not seen any settings relating to CC.

Maybe it just feels quicker because the car is doing the accelerating.

 

Pressing resume on mine completely changes how the gearbox shifts gear.

 

The changes aren't as instant and it kind of does lazy changes to keep the acceleration constant and smooth. It also changes much earlier than flooring the throttle and doesn't rev right out. It than stays in 5th for a lot longer till it gradually settles on the exact speed then goes to 6th.

Judging my the replies above I am wrong about the acceleration cancelling the cc.  Probably just relying on my ancient memory too much instead of RTFM!  I have used it a couple of times in the week or more I have had the car but the thing I find annoying is that the stalk and controls are not in my view when driving so I have to crane my neck up to see what is what as I cannot do it from knowledge just yet.  It will come with time but controls should be visible all the time although I do accept with the variables of position of seat and steering column that would be difficult for all the different sizes f drivers.

I must be wrong too, I was sure the accelerator cancelled the set speed on both of the Scout and vRS.

Sorry for any confusion guys.

I seem to think that if you exceed the set speed by a certain percentage the cruise control disengages. Could it be this?

Possibly Phil.  I certainly have come across this before with other cars with cc before.  I will have a go in the car tomorrow as I said and report back but in the back of my mind I think you are right in what you say.

In the Superb silver1011? Mine doesn't do this.

Not sure, I do recall having had the CC on around 40mph (roadworks) and then manually accelerated with CC still on upto 80mph+ and it was still active (at 40mph).

I was going to say the same, I've never seen the accelerator cancel the cruise control even when going a fair bit above the set speed which I've done coming out of roadworks.

 

I liked the CC system as it seemed very simple to me and worked well whereas comparatively the Mazda system is bizarre...it's made up of on, off, cancel, resume, plus/minus, just a complicated mess in comparison.

No, my mistake.

Cheers for the responses guys. Seems to have caused a bit of a debate this

 

For the record and me personally, pressing the accelerator increases the speed whilst CC is active and then lifting your foot off the pedal reduces the speed to what it was last at.

 

I still seem to be struggling with this and have consulted the manual for clarification. Took it out today as I had to run an errand (passed a Black Octy FL VRS M62 Liverpool/Southport - was it you)??

 

Still seems to me when I reduce speed by 'holding' the - trigger down to decelerate that when I reach the desired speed, the car now and again surges back to what it was even though I haven't set it.

 

Seems rather odd but I need to do a few more runs so I can be absolutely sure. Either way, something ain't right and it's a shame because it's my first Skoda and I flippin' love it.

So if you've got the cruise control set at 70 and hold the minus button to bring it down to 60, it sometimes goes back up to 70?  I agree that doesn't sound right and don't recall mine ever doing that.

 

John

I recommend to reduce speed on the cruise control:

 

1) Nudge the top on/off switch slightly to the RIGHT until you feel slight resistance, this will disengage the cruise control without you having to brake/dip the clutch/turn CC off completely

2) Allow the car to decelerate to the new speed you want

3) Press the bottom end of the rocker switch on the end of the stalk - this will set the cruise speed to your current speed

 

I did have similar problems on a Mk5 Golf in the same way you describe - sometimes it would surge, but the above method worked 99 times out of 100 even with that fault, and I've never had an unexpected CC surge on my VRS.

 

(edited to say right not left!)

That's how I do it because just holding the '-' button until reaching the desired speed never seemed to give me the speed I expected.

Almost as though the CC speed was lagging behind the cars actual speed.

OK checked mine out yesterday and the acceleration does not cancel the cc and it does resume to the set speed once you slow down.  Tried both a brief burst and a prolonged higher speed and each time it returned as stated.

 

Hope that helps and sorry for any confusion I may have caused.  Not withstanding that the op's cc still should not do what he says it is doing.
