I wonder how important this is for older models, more so for pre-face lift?

 

A very well done explanation covering possible issues. What I liked was the explanation of symptoms, what to look for or listen for. I have a MY2017, and even though I've already had the water pipes, water pump and supercharger replaced under warranty, the replacements could go bad at any time. Interesting to see on the cats... expected lifetime. Going to put this link in my file. Thank you for posting!
