Hey guys, I recently purchased a 2012 ML350 Bluetec. Vehicle has 178,000km on it. However, there is an oil leak and I’m trying to figure out the source. The leak is leaving stains on the driveway and upon removing the cover, I noticed the small oil pan (with the drain plug for oil change) soaked in oil. Is the leak from that small oil pan itself or is it most likely from above? If from above, does anyone know what it could be that drains past that oil pan? I’ve heard of engine oil cooler seals being a common issue with these vehicles. When the engine oil cooler seal leaks, does it drip down that way? Any information and/or insight would be great.

Cheers.
