Howdy Sean, Kurt here, uh, your Mercedes dealership theory is not far off for sure. Uh, they only have 1 or 2 texts capable of doing real in-depth. Diagnostics at most, of those dealerships, maybe 1 or 2, Master techs, like me, uh, you know, rather than doing actual real diag or even at the bare minimum, a repair confirmation. They saw a technical service bulletins, AKA TSB that pertain to your situation. Uh, hit it called it. Good at the bare minimum they should have, uh, like I said, in the repair confirmation, which may have been 1 or 2 test drives, see if the code popped back up. It might not happen on the first test drive. It might take what's called 2 drive cycles for the proper monitor to run. And uh yeah they're just lazy and like you said, didn't want to do it Kick the Can down the road but they should have a warranty on that Diagnostics and quote unquote repair and you should absolutely go back to them screaming about how they didn't fix it. But the wiggle pop pop pop.
