Hi guys. Have a 2007 e60 530d that has an oil leak around the back of the vacuum pump, I was doing rocker cover at same time so while I was there I replaced both seals and was ok todo. After a day or 2 i am still leaking oil from what seems to be the rear of the pump? 1. Any one had this issue before and managed to fix? 2. Any guide on removing the pump on it's own, does egr cooler have to be fully removed?
