Hi all, Probably a dumb question but I'm struggling with finding oil level check on speedo cluster. I don't have the handbook to check the "how to". It's easy on my 270 CLK as it's a simple option from steering wheel controls, not so it seems on my 320 CDI Sport! I have tried putting the display on temperature display and then pressing the reset button 3 times which opens up a separate menu starting with battery voltage as I had been advised elsewhere but there is no display to show oil level check, obviously I did this on key position 1 and awaited display offering oil level check but nothing has come up ...... Confused or ill-informed? Thanks in advance. .
