Have an 01b5s4 avant w 100k. Brought it in for a leaking water coolant hose ... ended up doing some heavy work- water pump, timing belt, timing chain, tensioners, breather hose assembly, you name it - $4k in all.

Driving it home today picked up two codes:
P1519 air intake system and p1522 solenoid valve.

Can anyone help suggest if/how the recent work may be connected to this?

Is there a way to address this without pulling the engine??

Many thanks -
