New to me 35d with no service records where to start?

[Jryanbass]

Hi everyone! I just bought a 2011 35d with 140k miles. I don’t have a good service history on it, just after I bought it it threw the exhaust recirculation code and had a stored NOX code. I plan on deleting it entirely but I need to save up some money. Where can I start in the mean time? If you had One with no service history outside oil changes, what would you do first?
