Service was completed and I was informed that they had updated the transmission software as an update was available
Now when I switch out of Comfort to just Sport Mode the exhaust note does not change like it used to
Is the lack of exhaust note change just at ideal speed, or while Your moving..?
All I can add is mine is a 2019 SLC 43 AMG and mine jerks at low speed in Sport+ (10-20 ish mph)
I was also told that there were no software updates for my car last week (I had it checked as it was a week before the 1 year warranty ran out and my check engine light came on and it went into limp home mode on accelerating off a roundabout.)
There was a fault code on diagnostic - cylinder misfire but no cause found and it looks like they were thorough checking for possibilities.
My concern is it occurred just one week after my car's first service (again, before the warranty expired in case anything came up)
Two questions on the cylinder misfire:
1) Can You remember what fuel level You had at the point of misfire?
2) You didn't by any chance get the codes, or can phone back & ask for them, as I've had a very similar problem & have the same MY19/390bhp engine as You..
I pulled the following codes - Google'd them but not able to say exactly what they are for My R172, which is newer that the SW on Col's code reader:
* P030022 - Possible coil pack..?
* P030200 + P030300 - Possible cylinder misfire codes..?
I've not yet gone to the MB dealer about these codes, as it's not played up since...
