I just want to make it clear for all who read this in the future, that this repair was Only necessary b/c I negligently (did not understand how it worked) broke the Clock-spring.

I think it was quite easy to simply replace the heated wheel and clock-spring. Just involves a few bolts and plugging connectors together. Because I've done it twice now, I am guessing it would only take 20-30 min to do it again. Very straight forward. The toughest thing might have been installing the relay inside the glove box area.
