Amber ABS, BAS and ESP lights come on and stay on. am I doing any further harm to drive with these showing? I appreciate that the functions may not be operating and I shall have to get them fixed before the MOT later this month. I left the ignition on, without the engine running, for a few hours whilst and after I fiddled with the aerial (lubricating it whilst putting it up and down), could this have burned anything?

Someone else has suggested that worn brake pads may be the cause??

Thanks in hope.
