on a serious note, it can come up in combination with ABS/TCS problems which in turn may be related to low battery volts or to a failed accumulator. because its considered not user servicable its not a self-resetting fault and can only be reset with a full-scale diagnostic tool. its possible that whoever had it before you fixed the other problems but didn't have the tool to reset this fault. the other place the fault can often originate is the fusebox. so I would suggest you first check your battery and fuses and relays. then then find someone who can reset the code. if it doesn't come back, you're sorted but if it does then get a professional to look at it. at least that's what i'd do.
