Anyone else having issue with the cruise control? I have read the instructions and usually it works, I tend to use it in roadworks and the M25 in the variable speed limit zone during not too busy traffic.

Yesterday when trying to change the setting to 50mph (reset at that speed) my car accelerated on it's own trying to get to the previous 70mph setting! It did this twice then I turned it off, then reset it again and it held 50mph.

I am sure it is only supposed to catch the speed previously set when you exceed the preset speed and press the button and let it drop down and take over. Has anyone else had the car accelerate on it's own when trying to change the cruise speed? :eek:

I think this might be one for the dealer to look at! :mad:

What did you do to try to reset it to 50?

Mine doesn't tend to hold the speed as closely as my 147 D did.
If i have the cruise set at 70 and approach a 60 limmit, i can either touch the brake, clutch (my preferred) or turn off the cruise stalk.
If i use my clutch or brake to release the cruise, when i get to 60 i can just lift the stalk once to reset it at 60.

If i don't use cruise at 60, at the end of it i press the resume button on the stalk and it zipps up to 70. sometimes it goes past the 70 upto 75-76 and holds there. Sometimes it will go upto 73 ish and drop back to 70. On slight down hills it will accelerate upto 75ish sometimes. I guess this because my petrol engine has less engine braking than the Diesel.

However if i have set the cruise to 60 and then accelerate to 70 and lift the stalk it just seems to add 1mph to the 60. I find it easier to turn the cruise switch off then on, then lift the stalk to set it back to 70.
Either that or when leaving the 60 limmit just use the stalk up to gradually build back up to 70.
Not sure if this help though

Yes.

I was using it at 75 (well 70mph on the satnav) and then I slowed for the roadworks, average speed check ones at 50mph and I tried to reset it at this speed. It made the car speed up somewhat!

I haven't used it for a few weeks but I remember it not resetting properly unless I turned it off first, which I didn't do this time, but previously it would simply not engage at the previous set speed, or not operate at the new speed I wanted rather than running away with itself!

I need to read the instructions again, I thought the button on the end was supposed to reset to the current speed if held for over 3 seconds, or engage at the previous speed once I had used the brake and got above the cruise speed.

In normal use if I accelerate and then take my foot off it takes control at the speed set, I did think that for safety reasons it was not supposed to speed up unless I held the lever up, which I do do to adjust the speed if there is space.

Button on the end is for returning to the previously set speed, which may have been cancelled by braking or changing gear. To set a new speed you lift and hold the stalk for a couple of seconds. Accelerating above an active cruise control speed does nothing - it stays active and you don't have to reset it.

Whilst we're on the subject, I find it a real pain that there isn't a cancel button. Just because I don't want cruise control on anymore doesn't mean I want to brake or change gear.

My cruise control stopped working the other week (green light on dash would not come on despite turning off/on several times) - Seems OK now and hasn't done it again since though so hopefully just a one off.
