Not very technical so please bear with me and thank you for your patience.
I have an SL500 on a 53 plate. Usually, when one opens the driver's door a low brake warning, start engine message comes up on the instrument panel.
Local MB dealer has had no luck at all in tracing any fault and the battery has been replaced. The message continues. There is no rhyme or reason for its appearance as far as I can see. It comes on after long drives, short drives, generally at random.
Any suggestions gratefully received, thank you.
