Morning,
I have a 2012 E350 Blutech. I got this fault code 15770, component Y27/9 [exhaust gas recirculation actuator] has an internal fault. This has been going off for a couple weeks, I reset it and in couple in a couple days it comes back. The car runs good so I don't think it is affecting performance. Can anyone tell me what it is and what could be causing it?
Thanks
Jim

Just an update, I was able to clean my EGR valve and fix the problem

Thanks for the update. I was just going to recommend cleaning it. Was it gummed up or sticky due to carbon and not moving freely?
