Just to let you people know ... there was indeed a malfunction ... the car was finally connected to the computer and reported something to do with the clutch that also affects
DSC or turns on the same light ... didn't get the explanation very well sorry!
Anyhow, I felt as if the car seemed more wobbly while the light was on, so I assume that
DSC was off ... it did not happen again after the car was switch off ... but anyway it's already been fixed!
Thanks again for the replies!
