MERCEDES-BENZ:"DEVIATIONS" I GOT ONE , TEST THE CAPS!
LAST YEAR NOV. 26, 2012, FUEL CAP NOT PERFORMED ON A 1990 MERZ 560SEC. I TESTED ANOTHER 1990 MERZ 420SEL, WITH THE PINK ADAPTER IT PASSED THE TEST. THE PINK CAP ARE FOR SOME MERZ. AND SOME BMW. THE RED W/WHITE RING FOR MERZ.

If it caused a deviation, I would just submit the bar blast and refute it. It probably came up because for that year, make and model, more people tested it then not. The deviation does not necessarily mean that it was supposed to be tested, just that the majority did. That is why they have it written, that if you provide proof it should not have been tested, then they will correct the deviation.
My Stant Fuel Cap Testing Adapter Application Chart lists all Mercedes adapters as red until 1997. Not until 1998 does it list another style fuel cap adapter.
