Hi,
The rear wiper is known to rust up after a while, and if your not bothered about your vehicle being 'pure', the vw unit is cheaper (easy to find second hand), and in my eyes better, than the audi unit, as it sprays straight up giving a decent coverage of the glass.
I've seen the lock problem esle where on this forum. Notsure on the other one. Sorry I ca't be of more help
