2019 C300 Issues

Hi All,

I wanted to come and see if others with the 2019 C300 have experienced any of the below issues and how they potentially resolved them.
  • First thing can't be resolved... but I had a 2016 C300 and I'm positive my 2016 had more interior room, but dimensions posted and dealership are adamant they're the same. I can tell the hood is shorter, driver and passenger windows smaller, front windshield angled differently etc. I didn't notice during test drives, but I notice now that I've had it about a week.
  • Mercedes Me Connect... man this thing is frustrating. Mercedes Me worked fine for me before on day 1. After a week, services finally show active in the app and it tracks gas, mileage etc... but it cannot perform any remote services without giving me a "due to a technical error" message.
  • A/C on passenger side is hot on certain fan speed settings... for instance it's spitting out hot air on level 7 and only if I have the fans coming out the face vents, but if I switch it up to both face/feet... it turns cold (only on passenger side, driver side is fine). Weirdest thing ever and I have a bad feeling dealership won't be able to resolve this.
Other than these, ride is nice but still frustrated over it.

I take it with the A/C that you understand the "Sync" control?

Yup I do. Both set to "Lo" on temp regardless if sync is on or off.

If you run "manual lo" too long - the evaporator starts to "frost up" which reduces the cooling efficiency - which for most people then reinforces their urge to stay on "manual lo" - and "manual lo" too long and later starts the "moldy gym shoe smell" in your climate control.

Best to learn a bit of faith and set on a "reasonable" Auto Temp..

It doesn't matter if it's on Lo or 66, or 70. The replicating pattern I've figured out is any setting with the fan speed on 6 or 7 will cause the passenger side air to be from the outside. Responses of set "Auto" are nice, but there's still a problem i want fixed lol

You're just wrong here lol

the 19 comes with a sunroof as standard which would be the only difference in interior space if the 16 did not have one. The body is the same - the panels are the same.

+1 For you being wrong about interior. It's just a facelift. Aside from displays, they're the same.

Yea, I'm probably just remembering things differently on it. It just feels different to me.

I too had a 2016 C300, and recently replaced it with a 2019 C300. For me the interior actually feels larger (though as has been pointed out, it's the same). That's because this time I got a beige interior, and my 2016 had a black interior. The lighter color gives the illusion (to me at least) that the interior is more spacious than the black was. What color is your interior.

I don't bother using Me Connect, so I can't comment on that.

A/C on "low"? The whole point of having a digital setting is so that you can set the temp EXACTLY how you want. Sometimes in the summer, after I've done sports or something, I want it at 66. Other times I want it at 70. My fan is usually at 2 or 3, and I take advantage of the maneuverability of the vents to blow exactly where I want, like right on my face, or sometimes not on my face but on my legs, or etc. Have you tried adjusting the vent directions? I choose, depending on the situation, exactly how cool or warm I want the temp to be, by its digital number. Why aren't you using this?

So interesting you say this... I previously had beige and now I have black. So this makes sense haha.

My comment of it being on "low" was just as an example... it didn't matter what temp I had it on. It's in the shop now and dealer has confirmed there's an issue and they're looking into it.

Mine had a/c issues as well, there's a post on the forum I put up regarding. Dealership replaced the a/c control panel and it's been working correctly ever since.
