Nov 2008 320d Msport auto.
Had been out all ok.
30mins later, started car, and a yellow clock illuminated, with no digital clock display, just 2 lines
Trip meter had gone from 546miles to zeros.
Then a warning amber triangle was displayed, no other lights displayed
Everything else worked ok, eventually reset the clock, and trip meter started working from zero.
Anybody any ideas as to what caused the problems?
