S 320 cdi (W221 2006)
How to clear air conditioning error codes?
Hi

After a gas filling my AC indicator remain in OFF.

I am afraid I need to delete the previous error codes due to low gas pressure
or maybe do a system reset.

I have read in other Mercedes class there are a combination of keys that allow to enter to the Air Conditioning analysis mode and then you can erase errors

Can anyone help me on how to do it?

Thanks in advance,

W221 S class 2007
