If the Stability programme is faulty in a Coupe, should a warning light or anything come on?
Recently I have had two occasions where the back end of the car has gone, and no light came on to say ESP had kicked in or anything?
So...i am assuming that either the car figured out that there wasn't an issue in the first place and it wasn't going to do anything, or the ESP isn't working.
I must admit though that when the back end went out, i was too busy concentrating on the road and cars around me rather than looking to see whether a light came on.
Fun fact for the day; Daimler Chrysler holds the trademark for ESP, which is why everyone else uses some other abbreviation, like ASP, ASC, VSC, DSC, etc..
