Recently brought the car in for a routine inspection. Everything checked out fine but tech says there was a oily residue moisture buildup on the wastegate actuator.

Asked if it rattled or if it was on coolant lines etc, repeated just on the actuator.

Anything to worry about? Thinking of taking to another shop for second opinion

I believe VCG can leak onto WG actuator, DP, etc.

I took a peak at the VC and it looks clean, I'll fully inspect it when I get the time. Just worried me for the infamous Wastegate rattle.

That's more a N54 problem. I've never heard of it on N55 really, especially not EWG. I would be more concerned about the oil than potential rattle. Probably no imminent danger, but could be the early signs of a leak.
