i cam across a weird fault on my fabia vrs before, i was getting ready to pull out of my drive with the steering wheel on full lock to the right, then suddenly i hear 3 beeps and my abs light and handbrake light and traction control light came up 3 times and went off, so i tried to fault it again and it happened again, only happens every so often but now and again it also can cut my power steering out? i have had it on diagnostics, they couldnt find a fault, but the light thing didnt happen there. Any ideas???

Needs new battery
