new owner questions
I have the 2018 C63s Sedan and have few questions
1 ) Window sticker says break-in period 1k miles ( I'm about 700 miles ) but few threads say up to 800 miles should be fine for the break-in period. So is it 1k or 800?
2 ) In Comfort mode when the car is stopped it's always in 2nd gear ( never see it going to 1st gear ) and there is always this jerk shifting from 2nd to 3rd gear ( is this normal or should I take it into dealer so they can have a look at it? )
3 ) Road noise from tires is just too much ( do you guys think a change to good brand run flats will reduce the noise?
Thanks
2) In Comfort mode, the transmission will always start in 2nd by design. I don't drive in Comfort often, but don't recall any kind of jerking on the 2-3 upshift
3) Run flat tires will NEVER be the solution for excess road noise. I don't recall what '18s came with for tires, but unless they're particularly noisy I'd say that's pretty much par for the course. You're running wide high-performance tires, they're almost always going to be noisier than an all-season designed for comfort. You could check TireRack and see how what you have now compares with other options; they have tens of thousands of reviews.
The car will always start in 2nd gear in comfort. you can always switch into sport or sport + and it will start in 1st and wont activate stop/start.
Personally I didn't care for the stock tires or run flats in general. Check out some PS4 or whatever tires you've had on previous cars that you like.
