[V6-12v] Timing Belt Tensioner Torque Setting

[James Whitehouse]

Hi Marc,

Darn it, but I already did it up, and put the V-belt and covers back on! LOL

Seriously, if anyone has the spec. and could let me know whether I need to
go back in there and up the torque, I'd be grateful.

FYI my local garage looked it up in their standard tech book (where they
have procedures for all the timing belts on every car in Christendom) and it
says: pull the 8mm allen key to 4Nm to tension the belt, then tighten the
bolt to 45Nm.

This still doesn't explain why the Audi workshop manual says 22Nm for an M8
and 43 for an M10.

Help!

James
