Question MY15 Recall Software Update

I took my 2015 C-Class for service and they mentioned that there is a recall requiring a software update. I did the update anyway, but I can't seem to find information about the recall in the NHTSA site.

My invoice shows the following:
C Campaign No. 2019030023, *** Update powertrain control unit (PTCU) software

Anyone know what this software update fixes?

Welcome to Benzworld!

I had exactly the same recall work done on my 2015 C300 when I took my car to the dealer for some other issue in April. I never received any recall notice either. When I inquired I was told that it was a transmission software upgrade.

After that I did notice that in Comfort mode, the shifting is little less aggressive then it was before. Still I think in Comfort mode, the shift is still not smooth as it should be.

Please put you location in your profile. You will get better response if we know where you are located and also members in your area can give your specific recommendation especially wrt to mechanics and shops.
