Fairly new member, picked up an '11 M-sport back in June. Really enjoying the car, but my first dreaded SES light came on yesterday. Read it as code P20EE, which from brief search sounds like 4D16 which sounds like an expensive wild goose chase. I'm so new to diesels, all the threads have my head spinning on the references to the different parts.

Hoping maybe someone might have a shop recommendation in the Portland area. Rather not take it somewhere that hasn't seen this before and just starts speculating with expensive parts.

Car has about 78k miles, so it passed the sh!t-out-of-luck point a while back for warranty. Have an aftermarket warranty, but won't cover any of this I imagine.

Thanks in advance.
