2006 A4 intermittent check engine
Just dropped nearly $600 at reputable shop on repairs, but source of check engine issue was not isolated.
Intermittent check engine on a 2006 A4, 70000 miles.
Shop reported these codes,
16891-oxs senser
16825 - evaporator flow
16891 - IAC (Whats an IAC?)
18619 - too lean
P0089 - fuel PSI
P0171 - B-bank 1 lean
P0441 - Evaporator
Shop also reported water pump leak, recommending R&R, and recommended new timing belt, neither of which should be related to the intermittent check engine light.
Please advise if able to suggest next action when check engine light comes on again.

You have 2 lean codes , idle air control & oxygen sensor faults. I would have the fuel pressure checked along with checking the intake system for any leaks.
The evap code could be tied into it also. Have them check the purge control valve & see if it holds vacuum.It could be leaking causing lean codes.
The timing belt is a maintenance item & should not be a factor with the codes you are getting.
