I experienced the following this evening whilst driving my 2009 330D on the freeway - there was a sudden power loss and a burning smell.

I pulled off to the side and noticed smoke from under the hood but it was too dark to identify the cause.

Attempting to start the engine again, the starter runs as normal but the car won't start.

I had the car towed home and then looked under the hood. There's a fair amount of oil visible on the left side (when viewed from the front) of the engine compartment with splashes visible on the air filter box and surroundings.

The car showed no signs of unusual behaviour or unusual engine sounds prior to this happening.

Any suggestions on where I might start looking?

Thanks in advance.
