Hello everyone,

I just bought 3 month ago my first Mercedes Benz car and I'm encountering an issue with the air conditioning system in my 2016 Mercedes S500 Plug-in Hybrid, and I'm hoping to get some guidance or advice from fellow enthusiasts.

The Problem:

My AC has stopped working altogether.
Upon connecting a diagnostic tool, I received the following error codes:

B229249 The electric refrigerant compressor has a malfunction. There is an internal electrical fault.

B229271 The electric refrigerant compressor has a malfunction. The actuator is blocked.

B229400 The electric motor of the electric refrigerant compressor is blocked.

Steps Taken:

I've already visited the dealership, and they've recommended replacing the compressor, but I'm hesitant and seeking further advice.
What I'm Looking For:

Insights from anyone who has experienced similar issues or has expertise in Mercedes AC systems.
Suggestions on potential root causes beyond compressor failure.
Guidance on whether replacing the compressor is the best course of action or if there are other troubleshooting steps I should consider.
Any help or suggestions would be greatly appreciated. Thank you in advance for your assistance!

Thanks!
