I've a 2019 C43, have 7000 miles. I went to the dealer for an oil change (I know, I know, the next one is in the driveway) partly to see the dealer operation and because I wanted to do my usual 5-8K oil change intervals. ( I plan for 5,000 but get to it by 8,000-ran a BMW M54 334k miles that way....) They were not supposed to reset my service monitor, but did so anyway. The receipts only show the oil change and a car wash, but the car builds boost faster and seems quicker. I was running 4.7 seconds on the track pace, but now 4.5 to 60. It literally felt different when I got onto the road outside the dealer.

I don't understand how the car could both feel and objectively be quicker-is there some sort of quiet update being done to something ? Is there some mystery programming once you do the first resetI - I didn't have any complaints before and didn't complain about anything to the dealer.

Bizarre.
