AERO8 2007 S3 warning lights coming on. First the RH indicator light stayed on. Then others started to glow slightly and then got brighter. Seatbelt light came on and unable to reset by disconnect and reconnect belts. Handbrake light on a nd no reset by handbrake operation. Occasional high pitch alarm as when ignition switch is initially operated. Alarm again when sidelights switched on but goes off when switched to headlights and stays off when switched back to sidelights. No apparent problems otherwise with vehicle functions. Had driven in some wet weather and recently filled with E10 fuel when E5 not available. Any ideas? This is my first post so apologies if not conforming.
