2000 2.7T
 

Hello,
I need an expert estimate ($$$) regarding passing the NY inspection (I wasn’t bothering if it wasn’t the inspection, the car runs perfectly), the following Codes appear on OBD that the shop pulled:
P0421
P1411
P1423
And the check engine light is on.
Audi 2000 2.7T, 67,000 Miles.
Thanks.
