Hi everyone,

I have a 2011 S40 T5. I have traced my AC problems to a bad AC low pressure switch. I read in this this forum that with other models, you can simply unscrew the old one and put the new one without needing to drain the system of freon.

I just wanted to confirm with the "experts" out there if this is the case with the 2011 S40 T5. Can I simply replace the low pressure switch without losing any freon?

Thanks in advance for the help
