First the 'power steering failure' warning flashed up - for a second. Then it disappeared. Then it was 'Brakes failure! STOP!'. That, too, disappeared after a fraction of a second. The car got me home with no issues.
Went out to it a few hours later and turned the key - no response from engine, but displays started going on and off - as did the wipers, headlamps and all other stuff; it acted as tho' possessed. It finally started, so off I went - with 'beeps', warnings, single-wipes, the odd display flicker and finally a loss of the speedo reading throughout my 10 minute journey.
What the? Any ideas?!
