No it doesnt. It's an Amber warning only. No action needed but for me I use it to gauge when the EGR needs a service.

No, the DPF is healthy with a reasonable soot level but I don't use the car for short journeys. When I checked the EGR valve I could feel gunk stuck to the valve shaft and cleaning it properly seemed to resolve the issue.

Add to that the complexity and requirement of cooling the gases now, and as the internet says, you have an extra service item to be completed. As you say a couple of TB gaskets and regular cleaning should keep it at bay.

A reset of the throttle body via Vida restores the engines inherent smoothness.

managed to get dealer to replace that under warranty. I have a good dealer with a head tech who owns the same car as me.

I think a catch can would upset the system.
As for oil, same as you except I change it twice in a year and at 86k miles no usage to report.
