I have just bought an eclass 2.4 avantgarde and the BAS light won't go off even though I have changed the switch, can anyone recommend a solution?

It be very helpful to know what year the car is.

Did you clean the connector? Its a long shot at best but worth a try

Bad switch usually is giving different symptoms.
OP did not post the location, but I doubt with this engine he is in America where we have to pay $150 too hook up the car to computer.
So if you can have the car scanned on SD for just few bucks, why not to save the aggravation on blindly dropping the parts in?
