Help needed from 03/04 M45 owners

[CarbonFiber]

I Recently just purchased my 2nd m45. Everything seemed fine the first week but just recently the vdc and abs light have come on along with the "slip" light. It comes on randomly and if i turn the car off and restart it the lights go away. Anybody have any idea what can be causing this to happend?

Also the speakers barely produce any sound. they work but are very low even when i have the volume at full. anybody have any idea why that is and what i should check for? Any help is appreciated!

start by topping off your brake fluid. i only needed a small amount to make my lights go away.

can't help on the stereo

Thanks you I will do that today. As for the speakers i keep hearing that the head unit has crapped out. i hope that isnt the case.
