So I just hit 50,000 miles on my 2010 C63 the other day and I noticed I have a MIL light. When I pulled the code, it was P0391

It's as if I have a wiring or computer issue, any thoughts?

Checked my belt, and it's badly frayed on the inside edge. I wonder if a piece of it flew off and cut a wire? It's so tight in there trying to check...

Yes, looks like a cable leading to several camshaft hall sensors is interrupted. I am just surprised about the tank sensor message. That one sounds like something different.

There should be a cabLe that is frayed or a connector unplugged somewhere in a cable leading to the cylinder head, where the camshafts are.

found the shredded wires on the driver's side cam angle sensor. Still trying to locate wires to the oil temp sensor.
