48v Software Update campaign
my car was in the shop for the MBtex split replacement. Got it back today with new cover on driver’s side and will go back once the passenger side part comes in.
They also did this without me asking - the 48v ICS Control Unit Software update. We’ve not had any of the problems that some of had with the 48v system in 3 years and 63k miles, but it appears that if you have a MB 48v vehicle in general prior to March 2023, they will update the software for you regardless if you ask or not. It’s a “campaign”, and that reference number is 2022100005. It applies to 2019-2022 model years for the E, CLS, GLE, GLS, S, AMG GT (213, 238, 257, 167, 223, 290)…
I am long past warranty, yet they charged me nothing for the update.
(PS: The other two campaigns in the picture were for the 3rd row seat locking mechanism and the rear door trim mounting bracket, neither of which was a problem for our car).

When I emailed my SA this morning re B service on my 20 GLS450 he said there were two open recalls. On the NHTSA site only the air conditioning hose recall is shown, so this campaign may be the other.
I googled and found this:
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year 2019-2022 E, CLS, GLE, GLS, S & AMG GT-Class (213, 238, 257, 167, 223, 290), the affected vehicles may not meet current On Board Diagnostics (“OBD”) emissions specifications. Under certain conditions, the permanent OBD fault code memory of the 48V ISG control unit may not activate. An authorized Mercedes- Benz dealer will update the software in the affected vehicles.
Update at 3:45 pm: just set my service appointment and the 48v software update is the other recall listed.

thanks for posting the google results! Interesting to read that. Would be curious if the google results show the campaign number too? That would confirm it if possible. Would actually make me feel better about it, since we’ve never had the 48v dead car issue before, would rather leave well-enough alone!

i believe there is a difference between a “recall” and a “campaign”. Lawyer jargon is my guess.

I googled the campaign number and found this link. When I clicked on it the pdf document came up 48v Software update

Correct, recalls are widespread safety or emissions related issues that get the government involved. Campaigns are non-safety issues that the manufacturer decided to voluntarily fix on all affected vehicles to improve drivability. They generally get automatically done next time the car is brought in for service as they show up in the system for each affected VIN. The next level down are LINs, which are technical bulletins that only get applied in response to an actual customer complaint.

As I read it, this is an emissions related recall with a fault code not triggering on the OBD properly. Doesn’t appear to have anything to do with the 48v battery problem that some owners have had.

I just called my service dept and gave them the campaign number 2022100005. They said it was closed. I bought my 2020 450 in August of this year (CPO). When I check mbusa recalls on the site it lists 4 others that are completed but no mention of 2022100005.
