Hi, I’ve noticed some oil under my car (3-4 inches spots) - passenger side, pretty close to radiator area. I’ve bought the car (ML 350 Bluetec diesel 2013) in July ‘21; dealership was informed weeks ago but didn’t respond to my inquiries.
I suspect the oil cooler seal to be the cause.
Need some advice:
- is there any way to identify that 100% (or close)?
- I saw some bar leaks repair liquid advertised around. Would they help?
- What’s the typical cost of repair in Midwest KS?
- is this someway covered under mb Bluetec settlement?

by the way - I also have check engine one with p246f dtc code identified. It goes on and off. I assume it’s caused by the DEF sensor. It typically goes away with some driving on highway. Any suggestions?

thanks!
