E39 540 DSC Light On NOT ABS!

Hi all

My e39 540 DSC light is permanently on. All the searches refer to the ABS and DSC light on, but mine is just the DSC light on. The car has recently had new front discs/pads/pad sensor, brake fluid, battery, climate resistor, but the light was on before that anyway.

A few other searches suggest various wheel/speed sensors, but the speedo works fine as does the cruise control and all other functions/features on the car.

Other searches suggest ABS module, but then surely ABS light would be on as well? ABS 100 % works, no other warning lights on, just getting a little annoying every time I put my foot down hard I chirp the tyres, not too bad in the dry, not great in the wet though lol. I had a mate pop round with a laptop & data cable plugged it in somewhere under the dash, no faults found! I'm baffled! Anybody with any ideas before I have to take car to the garage?

Thanks in advance
