Absolutely correct.  Timing is derived by complex software algorithms
that primarily use the flywheel pegs and teeth to provide accurate
information on the crankshaft position, and the Hall Effect sensor to
differentiate firing from non-firing TDCs.  The distributor merely
picks which of the plugs is going to get the spark - it doesn't
determine when.

May I add a word during ignition discussions?

A lot of the components specified by Audi have resistive functions -
some rotor arms and plug caps have 1k ohm or 5 k ohm nominal resistance.

IME these values are _important_.
