[V8] Snapped off a bolt

[toml99 at todomundo.com]

If you are talking about one of those 2 fasteners that also are what  
the plastic plug wire cover get's attached to, then it's not a "bolt"  
per se, it's an Audi Part # 077103714 D(front or E for rear).  I'd  
check junkyard or ask who's got a dead motor that would part with  
one.  For anything under 25 ft/lbs, I use my In/lb torque wrench and  
multiply by 12.  Good luck, Tom
