Nuieve

2014. Car is under MB extended warranty. Dealer suggests this issue is likely not covered, and wants $150 to just diagnose.
I just want the message gone (on every startup). I don't want to commit unless I know for sure. Otherwise I'll keep clicking ok button for the next few yeaes.

In my experience MB is probably the worst in the world and almost never covers anything based on my experience with 4 cars... so I won't be surprised. Anyone familiar with this issue?
