Hi team,

Wanting some opinions and recommendations on some Aircon help with my C63. I regassed this with a local garage last summer and then around winter 2020 I got the dreaded 3 light flash when pressing the AC button in my car. I've just had an OBD plugged in and the readout is giving me the two fault codes above. Now it looks like the Aircon needs regassing, but other than putting more money into again, I wanted to make sure that these fault codes don't relate to the sensor or compressor? [I do have a Merc warranty but that will be £100 for diagnostics and then probably won't be covered for those fault codes] Leaks have been tested for before and none were found.

Secondly, does anyone have recommendations for an Aircon specialist around the Berks,Bucks and Herts region?


Thanks!
 

You can check the pressure yourself to see if you have lost any refrigerant. It is quite simple to do . Obviously a proper vacuum, dry , re gas , leak test should be done by the experts . but checking it is quite easy with a cheap kit like this.
