Belt tensioner lower allen bolt..

[Ivan Demkovitch]

Hi!

Decided to replace noisy bearing in belt tensioner (93' S4)
It mounts by 3 allen bolts. Guess what - I snapped inside of lower bolt and 
have no idea on how to get it out. The only idea I have - is to put it back 
together and wait for Timing Belt job so I can remove radiators and get more 
space.

Any suggestion on how I can get it out?

Thanks!
