20V timing belt changing

re: "what is the suggested change interval for the timing belt"

According to Audi, there is none.  Zero.  But, then again,
they are in the engine business.  BMW reccomends 60K, and
I agree.  re: 10V vs 20V, remember that on a 10V engine, a
broken belt means, well, a broken belt.  On a 20V motor, it
generally means broken valves, etc.

Replacement on a 90 20V is quite laborious.  Remove the pulley,
the radiator, and a bucha brackets.  I gave up and had my
mechanic help me out (gota get to work!).  About $300 later,
all was well, including all new accessory belts and hoses
(good idea once you are in there).

Why, oh why, does Audi ignore the lowly chain?
