Confirming an Oil Leak (330i)

As the title states, I am trying to confirm an oil leak and need help. Last November, my 06' 330i suffered from an oil leak. Took it to the dealer and they said it was an Oil Filter Housing Gasket or Oil Pan Gasket. Took it to an indy and they replaced the OFHG only. I assumed that the leak was fixed, but while I was looking at the transmission earlier today, I discovered a somewhat major leak under the engine (See pictures below). I want to assume that it is the pan gasket that caused this but wanted to hit the forums before I started buying parts.





If it is the Oil Pan Gasket, what electrical sensors/wires should I replace that are down near there? Lots of oil seemed to have covered a few electrical things.

Thanks!!!

Looks like oil pan gasket. Just in case check your engine valve cover gasket too, if it is leaking and running down on the passenger side of the engine.
You don't need to replace anything electrical, just clean them with electrical cleaner spray.
