Getting ready to change doser at the turbo

And that crankcase filter, they make one that is no maintenance, around $70 -$120 at the dealer, If you do not have one, I would get one. The new crank case "filter" does not have the white filter element in it, it is just two pieces of plastic sandwiched together with a little breather button. install and forget about it.

Oh, your power steering fluid, would be a good time to replace the power steering filter, it is located inside the power steering fluid reservoir, directly in the fluid, it screws in/out, looks like a small oil filter.

Try FleetPride for both filters, much cheaper than the dealerships, that is if you have one in your area. You would be surprised at the parts you can get there.
