I have a 2001 S4. Just got back from a 1,100 mile trip.
Started to get a clanging sound when taking off in 1st gear (seemed fine in all other gears).
Just got done cleaning the chain, and found the front sprocket wiggles if I grab the front and rear of the sprocket and pull one one side, pushing on the other..
I presume for some reason the sprocket is failing in some way. Note, this is the sprocket with a cover plate and 2 allen bolts holding it on (not the single central nut).
Aside from replacing the sprocket, I presume the shaft is hardened steel, and should be OK.
BTW, the shaft itself has not play, and seems solid, so not a bearing issue.
Any ideas for the cause of the failure? My riding partner has the identical bike, and there is no play in his front sprocket.
