Air conditioning problem on a Mercedes V-Class Diesel

Hello everyone, I own a 2014 Mercedes V-Class with a diesel engine and 90,000 km on the odometer. After a battery failure, I replaced the old one with a new one as a precaution. However, the air conditioning system no longer engages and no warning lights come on on the control panel. I received a message indicating that the CAN message from the climate control unit is missing or incorrect, with fault code UO 164. Could someone help me solve this problem? Thank you in advance for your help. Sincerely, Joel FICHEL.

After replacing the battery in a 2014 Mercedes V-Class Diesel, the air conditioning system stopped functioning, and a fault code UO 164 indicated a missing or incorrect CAN message from the climate control unit. Possible causes include loose or disconnected wiring around the climate control unit due to the battery replacement. Suggested solutions include checking and securing all wiring connections and attempting a system reset by disconnecting the battery for 10 minutes.

Check if the battery replacement caused any loose or disconnected wiring, especially around the climate control unit. Ensure all connectors are securely attached. If the issue persists, try resetting the climate control system by disconnecting the battery for about 10 minutes and then reconnecting it. Let me know if this resolves the issue or if you need further assistance.
