they are in new mot rules if on must work unless an import as not fitted as standard but thought if there would have to work someone who knows more about it might come on but yours passed so happy days
not sure about hr but older jdm imports like mine dont have washers or self leveling headlights so fitting diffrent as there was a thread about new mot rules somewhere talking about this if you fit washers they will have to work for mot if you dont you will be ok as its an import
+1 Check levels but yours is reading as it should only time you will see it near the max is when your giving it some and even then wont max out or you levels are to high
i belive you can get what your after for the stering wheel as i seen a couple when looking at padels convertion for the auto/triptronic i will try and find it again and post later
