shocks shot @ 30k miles?
 

I replaced stock springs and shocks on A4 TDI with 17inch 5 spoke alloys at 80k miles with lowered springs/standard shock combination (Munroe).
Bounce test and driving feel indicate worn shocks at just 112k miles.

What is the typical live of these standard units? I would like to try Bilsteins on the front (the rear seems Ok).
Any recommendations, ie. Koni etc
