[AUS T5]

I just did mine and accessed the pump through the bottom of the left wheel arch. I pulled the two hoses out of the bottom and was expecting to get a flood of water gushing out but nothing happened although the reservoir was topped right up. I then removed what I thought was just a black washer in the outlet hole but it turned out to be a combined filter as well which was completely bunged up with goo (see first two photos and the last two after cleaning) I flushed the reservoir in situ and put it all back together and it’s now working like new.
