I mostly agree with Karl here. If the starter cranks as well (or poorly)
from the key as it does by jumpering the 50 terminal at the starter, then
there is nothing to be gained in terms of the starter working. If it
doesn't, then it's arguably as easy to fix the poor connection as to
install a starter relay. I say connection because wires don't get tired,
but crimps and connections do when left out in the weather the way VAG did.
That said, the relay does reduce the stress on ignition switch contacts.
The solenoid is an inductive load, so it arcs more at the switch contacts
than a similar resistive load. The switches I've taken apart (no Kostal
ones yet) show pitting and arc burns on the the center contact at the 30
terminal, which seems to do most of the actual make-and-break switching. I
tried to look at one just now to verify my recollection, but too many
pieces were missing for me to make sense of it. It's kind of a horror
inside -- the key-inserted switch complicates things considerably.
Yrs,
