Rear main seal leak in 2011 CPO E350 4MATIC
The good news is the repair is covered under warranty and the nearest MB dealership is going to repair it tomorrow. Shouldn't the MB dealership where I purchased the car have detected this when inspecting the car to "certify" it for CPO resale? I find it a little disturbing that it wasn't detected. I guess it's possible it started as a small leak that went undetected and then got worse over the past few weeks, but I think that is unlikely.
