Hello, Sometimes warning light gearbox lights up. Today I could not shift N was blinking when I get it in 1 it also blinks. Turn engine out and restart problem was gone. I made a testdrive and no problems? even in AUT mode shifting was ok. Could this be a problem of hydrolic oil level? When I open the door I hear the pump for a few seconds like normal. Or could it be poor battery Please give me some tips to check before I go to expensive dealer!! Thanks Chris
