Mercedes C300
Code 0521, 0814 & 0810
All,

I got Mercedes 2009 with a check engine light on, yesterday I ran an obd diagnostic and I got these three codes.

I have read a lot about them, and come some have said a about getting a new intake manifold or either a new secondary air pump.

any recommendations about ir, or some have had this issue before

Heres a thread: https://mbworld.org/forums/c-class-w...ode-p0521.html

I would visually inspect the front of the intake manifold for a broken lever rod, may be a worn ball joint also. other two codes may be related, maybe a vacuum issue.
