Cruise control not working

[raimon]

Hi guys,

The cruise control is no longer working on my car or is temperamental intermittent problem. It used to be just an occasional thing now it has become more frequent. Basically you turn on cc, light turns white, then you try to engage cruise control it just not working anymore not turning green, tried all sorts of methods on the controls to get it to work but no avail.

I have read up it could be a number of things to cause it. It could be the actual cruise control switch on the steering wheel, or brake sensor etc.

Any ideas.

Thanks.

First thing I would try is pulling the negative off the battery for 30-60 minutes let all system shut down.

If that fails it could be the brake position sensor at fault or any other item at fault I would say the button as the button is working ok to turn it on and I'm guessing all the other buttons work as they should?

If the battery pull doesn't resolve the issue the next thing is to plug it on ad see if any errors are coming up, if they are fix the issues.
If no errors I would try re-calibrating the brake pedal (MDI & sps needed for this).

Done the battery thing many times. Usually it works, then not working again day later.

The same thing happens to me often, I find when it stops working put your foot under the clutch pedal and lift it up a little and it then works again, also my cruise control dose not disengage when the clutch is pressed down but my other halfs astra dose so I am guessing its a fault with the clutch pedal somewhere.

I would have the car plugged onto GDS2 and check for any faults.
If none SPS the BCM & run through set-up and configure where it will relearn the pedal positions.

In my car I can change gear and accelerate wile CC is active and then it will take back over again it's not a fault its the way its designed, but IIRC it depends on engine and spec.

Its temperamental hit and miss when it decides to work.

I have exactly the same here - thought it was me!  Had the car 4. months and it was intermittent a couple of times then fine for ages.
Recently (cold weather) it ha started again.

I will try the battery trick suggested by Rusty 1st and see what happens.

I managed to sort mine finally, it was the clutch return spring at the very top of the pedal assembly, one side had popped out so in turn did not fully return the clutch pedal which stopped the cc being able to engage, took about 1 1/2 hours to do but pedal is spot on and no issues with the cc anymore.
Hope this helps

Tried this trick this morning and it worked straight away - will monitor and see how it goes over the next few weeks
