I changed mine a few years back, no need to code anything, although I did go for a genuine one (new/old stock on ebay). Never had an issue since.
As said, check with VCDS and if no joy, take it to an air con specialist who can pressure test the system. They can inject a UV dye which can then be detected to find the leak.
