Dashpots

[quk at isham-research.freeserve.co.uk]

I think it's time one or two people actually STUDIED how the
dashpot works and what it does.  The idea that it somehow
got left in there when Audi converted from carburettors is
ludicrous.

It doesn't slow the operation of the idle switch at all - quite
the reverse.  It allows the idle switch to close rapidly but
slows the butterfly valve, giving the ISV time to react.

If the system isn't working properly, removing the dashpot
just breaks it more.  Introducing a compensating error
because you're not up to fixing the real one is not good
engineering.

Dashpots do wear, and often need to be advanced a turn or
two to compensate.
