The fluid darkening is from the hoses and seals leaching their color into the fluid. Doesn't affect performance or life one bit. This is as BITOG OCD as it gets. Would you change the oil on a diesel as soon as IT gets dark? (Which is almost immediately.)
Someone needs to tell both Subaru and Mercedes that there is no reason to change power steering fluid. It's in the maintenance schedule for both of my cars.
It generates revenue for the dealers. Plus if there is a PS warrantee request, and you have not done it, they will use that to void the warrantee. German Cars are notorious for such things. I am a bit surprised with Subaru. Maybe they have a more legit reason.
