engine system service required
after a fair amount of dring in the snow and ice yesterday, whilst downshifting manually in the geartronic to reduce speed on a steep ice covered hill, i had the yellow warning light come up with "engine system service required ". temperature was only -3/-4 so not as bad as some areas in the uk.
i last had the annual service done 8000 miles ago - 6 months ago so it is not for the annual service.
it is a 185 D5 model. 2006 year.
when i took it out on a clear dual carriageway last night i have noticed that power is not effected - just this warning light.
does anyone have any ideas what this could be?
