Just ordered a set of osram bulbs and was looking at the Manual for headlight bulb replacement. Pretty straight forward it would seem. As these are German cars, I am curious if the right side headlight is reverse thread? The locking mechanism is counterclockwise on the driver side to release would it be the same for the right?

Second question on some online manuals it shows that the oil filler neck is extendable but not in my manual. I tried to twist the oil filler neck on my car, without to much force and it would appear not to move.

Can anyone please help validate.
