Hello, When installing the oil filter in my Q7 TDI, the small "extension" on the filter that drops into the hole in the oil filter housing did not line up correctly and broke off. When I tried to retrieve it, it fell in the other hole and I can not see it anywhere. I tried to use a vacuum to suck it out but no luck. Anyone know which way the oil flows through the housing or where that hole leads to? I'm trying to figure out what my next step should be. Thank you in advance.
