I noticed that the PSM and ABS failure indication were coming up when I started up. After a short journey stopping and restarting the engine the warning indication would clear so I put it down to it being cold.
However I have noticed that the warning lights can come on on start up, after a few miles or not at all.

I would appreciate if anyone has had this problem or can suggest the best way to overcome it.

Thanks in anticipation.

Minx.
 
There are three main culprits for this fault. A failing Mass Air Flow sensor can give false data to the engine control unit, which in turn feeds it to the ABS/PSM controller. A dodgy brake light switch or ABS sensor can also cause it.

Your best bet would be to get a diagnostic check done, which would show what is at fault.
