Desperately needing help. We recently purchased a Burstner Elegance i800 2013 plate. We are currently on route to Spain and in an Aire, somewhere South of the Millau Viaduct on the A75. The Oil pressure warning showed it needed topping up. We have oil on board. Armed with the handbook which shows diagrams for the dip stick and oil filler cap we have searched and searched and can’t find them. The A class is so compact under the bonnet. Everywhere is shut in France for the next 3 days so stuck ?? Merry Christmas everyone x
