timing belt

[Dave]

as grant stated, there is no difference between any of the 4.2l v8’s in the
timing belt, tensioners or rollers.  they are identical.  in fact iirc, even
the v6’s use the same belt!

 

the rs6 gets very hot, and has significantly more power, and torque down
low.  these will have an effect on timing belt life.  shame they didn’t spec
a better one.  at least the dealer is making it a bit more reasonable in
cost to the punters.

 

i do not view the replacement as a diy job.  whilst the service position
helps access, you need the special tools to lock the cams and the dealers
don’t let those go.

 

what is happening down under is that the 2nd-tier shops are becoming
familiar with these sorts of cars and are putting pricing pressure on the
dealer shops.  my mate’s s4 had the clutch done for ½ the price the dealer
wanted for the job.

Hard to say.  The only two things I could think of would be the excess
underhood temperature somehow affecting the Belt.  Rubber is not a fan of
heat.  However, I'm not so confident on that one.

The only other idea would be the increased power output under spirited
driving putting excess stress on the belt, stretching it or fatiguing it
early, which is a possibility.

Better yet, maybe Audi really has 0 desire to replace a blown up RS6 engine
and would rather they all be over-maintained.  30kmi is pretty short.
