Double check wiring to switch side of the starter relay? Remove relay, wire
starter back to OE then test? If its a used TDI starter, could it have a
flaw in the solenoid circuit which would cause this issue?

I know that the 50 circuit is disabled when ignition key is released to run
position  but some relays have a suppression component (diode) across the
85/86 legs (switch side of relay). If those legs were wired in reverse,
could the positive connected to the relay switch keep the switch closed
thus allow a small amount of voltage to flow back to the instrument
cluster?
