[Biturbos4] Turn signal problem on 2001 S4

[Scott]

This is the second time this failed. The first time it was fixed under
warranty.
The turn signal doesn't blink or blinks once. Anyone else have this problem
and know what needs to be replaced?
I think they (the dealer) replaced the hazard button in the middle of the
dash and broke the wood trim piece the last time.
