I failed my smog test due to a check engine light being on and when i scanned it with the vagcom the codes that came up were:

17544 - Fuel Trim: Bank 1 (Add)
P1136- 35- 00 System too Lean

16825 - EVAP Emission Control Sys
P0441- 35- 10 Incorrect Flow - Intermittent


I am unfamiliar with these codes so any suggestions will help... Im not sure if this is related, but the car also drops in idle and goes back to normal when i first start it and randomly while driving after i take it out of gear, (ie: when approaching a stop sign)
Could one of these codes be caused by a clogged fuel filter or possibly a failing fuel pump?? any help is greatly appreciated! thank you!!

I would say vacuum leak and dead SAI pump. I think that P0441 code is related to that. I ran a P0411 when mine went out. Somebody correct me if I'm wrong.
