I have a 2019 Tiguan S. I got the EPC light come on solid and disappear a few times then the solid Engine light come on and stay on (all within 24 hours). So I use my OBD2 scanner and get P30C0 “Manufacture Control”. I’ve had some people tell me it needs an oil change, someone else told me I’m using the wrong grade of gas. I only ever use 87 octane and it doesn’t call for anything higher so I’ve been fine. But I wanted to come here to ask someone who knows more about it and can guide me to what it may be. I haven’t noticed it shaking or in limp mode, so I’m confused. Any ideas?

Agreed generic scanners aren't much use. Aside from the expensive VCDS many including me use OBD11 which is VW specific and gives a detailed explanation of the fault together with details of date it stored it and if it's repeat how many times. Another good tool is carista, but I've no experience with that. Both of those scanners are affordable.
Over on the mk2 tiguan forum (Volkswagen Tiguan MK2 Forum (tiguanforums.co.uk) there's currently a discussion on octane, and whether 95 or 99 should be used, so yes 87 isn't great and because of this many US and Canadian members report carbon build up in the manifolds.
