2008 Octy 1.9Tdi PD 1Z5 BXE oil leak.

I've removed the plastic pan, cleaned everything up and inspected for wet areas.

The leak doesn't appear to come from the rear or bottom of the engine, or from the left hand side of the engine (fuel filter side).

The tandem pump at the top doesn't appear to be wet.

The leak appears to be higher up the engine and just below the oil filter housing where it does seem quite wet. The oil filter housing isn't leaking (from the top, at least).

I know how difficult these things are to locate, but wondered if anyone has any pointers.

The oil is definitely engine and not gearbox.

Any suggestions and possible fixes/checks would be welcome.

Think there is a gasket/rubber seal behind oil filter housing. May well be coming from there or perhaps rocker cover.

Thanks! I'll clean it a bit more and see if there are any tell tale signs. Difficult to get to to see without a lot of dismantling.
