Recall ALL W221s we have no idea what we are doing

remarkable 2017 recall (including all W221s)

Daimler AG (DAG'), the manufacturer of Mercedes-Benz vehicles, has determined that certain vehicles that received a control module coding update while at an authorized Mercedes-Benz Dealership between December 3, 2006 and December 5, 2016, might not function as intended. Depending on which vehicle control module was improperly coded, the potential malfunctions as well as their influences on the vehicle operation are not fully known, but may include the deployment of an incorrect airbag during a crash, incorrect seatbelt recognition status, engine control module with an incorrect maximum speed limit setting, among others, and may increase the risk of injury during a crash. An authorized Mercedes-Benz dealer will update the affected control modules on the affected vehicles.

and the dodgy ignition switch update from 2022

You did actually read it?

A whole 62 vehicles affected. Hardly grounds for mass hysteria😂

don't be too excited they never cured it - had my rear sam done in 2021 - ended up with errors - a year later they correctly updated SCN coding and the error went away (that bug had only been there since 2015 !!!)

and lets not discuss the EWS I mention that#s an ALL Merc with that style switch update - which sound like a nasty security issues - or naughty extras they so love to accidentally include
