You do not have 11-15 degrees of "chain stretch". Presumably you have a reading of 15 degrees which is to be compared to the specification of 11 degrees for the 05 camshaft. This would indicate 4 degrees of elongation.

Your hopes are dashed..........the side without the angle is the side that is read.

If you want perfection, you go to the dealer and order a Woodruff key, p/n 621 991 04 67 and install it between the cam sprocket and the camshaft............be very careful not to drop it in the abyss.............it'll wind up in China.
You should note that most of the vehicles on the forum have elongation that is in the range of yours (including my SD), and the performance is only marginally affected.
