I have tried to call several times, no joy. I just got home from my local Mercedes dealer. Talked him into giving me a free diagnostic and running it up the ladder to see if I can my IC replaced. The good: they ran the diag and concluded I need a new IC. The bad: "The campaign is closed and cannot be re-opened or amended."Jim, Call Brett Bennett at Western Star Freightliner in Houston, tx ( the shop that just replaced my ICU) and see if HE says the recall is closed. It looks like others are still getting their instrument panels replaced, so I think you are getting some bad information from your AZ dealer. I have preiviously received bad information from Mercedes customer service,....telling me that my Freightliner was a Dodge,(It is not) and that they were not even able to talk to me any more,......I wouldn't put much faith in anything they tell you.
I may have a unique problem in that my original campaign 2016040001 was performed in November 2016. My check engine light has been on for 2 1/2 years. Not until recently was the real fix discovered. I don't understand. There is another dealer in Anaheim, CA that may help but also cannot get a return phone call.
