This light came on today for the first time on my Astra Sport. At first it was brief and seemed to be on downhill braking. Then was on permanently but as switched back to occassionally.
Noticed that it twice seemed to idle erratically and stalled once in 2nd with clutch in rolling at 10mph.
The car sounds fine and goes as well as it used to. Any ideas what this could be?
Is it gonna cost a lot to?
Urgent help needed.
