14 q5 3.0 tdi weirdness need some help

[Explrths]

Long time reader and I've learned alot from the forum. But, can't seem to find what I'm looking for. I'm getting a weird kinda roughly idle after car is warm. In gas terms, it feels like a misfire. I do have a code...208a it think. Def injector stuck open. Pulling that out today to investigate. Is there anything else I should look at while it's on the lift?

You would probably feel at cold too, but good opportunity to check out the engine mounts.

You may want to inspect and clean the mountain of soot on the EGR valve, throttle body and intake manifold in the vicinity.

Thanks, was thinking of that. The codes are whats throwing me . It's on the list of maintance . The def codes are throwing me . I'm not familiar with diesel and how things work( I'm learning) I did check the def injector and it seemed clear. I know I'm checking the wiring/connections next. I'll post the codes.
