Given the horrible issues w/ EGR-DEF..are they fixed (really) for 2016 & 2017.

What is your question?

We're looking at motorhomes and the MB Diesel. This engine is really taking a beating over EGR-DEF issues and MB response (I've been through issues like this with the corp end of car companies. I feel the pain of people having to deal with these problems. I don't care what you pay for your car...car companys on the corp level are all the same). So, did MB ever REALLY fix this issue?? Thanks,
