Hi All, wanted to ask for some advice. I have a 991.1 GTS which I purchased last year. The car was registered January 2016 and I had understood was on a 2 year service interval, although I now have a message flick up that says interim service due in 28 days. The car has 12k miles and used on weekends, with no track days so not really hard use.
Any ideas?
