I had a malfunction message on my W203 today that says ' BAS Visit Workshop ' while driving. However, there did not seem to be any difference in the car's performance and braking. After switching the car off and re-starting ( the Microsoft way! ), the malfunction turned off and did not reappear after driving.

As my next workshop service visit is not due for some months yet, is this something that I should worry about, or leave it till the next service?
