Did you mean transistor, rather than resistor? I don't recall a resistor in
that circuit, but there's a transistor that gets broken leg syndrome, the
common failure in that area.

In some era, around '71, Bosch used a cardboard spacer under that
transistor, which tended to hold moisture, especially in damp climates. The
moisture caused the leads to rust thru. Yes, the transistor leads were
plated iron, which is more common than you might think.  

I use a plastic spacer when I replace that transistor.
