Golf mk7 / Re: VAQ Diff Oil Service

I have cleaned haldex pumps on a few Golf Rs when changing the oil and the filters always look filthy, i have ever only done 1 VAQ haldex diff pump, on my own CS40, and it was super clean.
I think the rear diff in an R must work alot harder than a FWD VAQ pump to create so much debris.
I think whilst you've dropped the oil out you may as well remove the pump and clean the filter, or you would always be thinking if it was clean or not??
Clogged filters make the pump run harder which is why they fail due to burning out.
