Hi there all! This is my first post on here, I own a 2010 e550 sedan, and got a 2014 E550 Coupe with 45k miles not too long ago (4 months). I got the OE tuning tune, and am getting an x3202 error code when trying to upload the tune. Has anybody ever had any experience with a code like this? Or know a fix on how to get it to work correctly? I have tried multiple things including re-downloading the correct tunes to the Mygenius. I use the key, and I do have it in position 2, and follow all the instructions on the screen.

I don't have experience with that code, you might find more answers in the C/A 207 forum which matches your 2014 coupe, it's just above this one in the menu list. Best of luck.

Thank you, I made a new threat over there also.
