Hello A8 tech. Your knowledge is great! I followed your advice and got my A4 wipers at least moving, not fast, but moving with WD40. My A4 only has 27k miles on it. Any idea how long a warranty would cover the linkages? Seems odd that this would occur on so many models according to the forum posts.
