i have this p1136 code
car is a 1999 audi a4 1.8t aeb tiptronic
list of things changed
Dv
n75
pressure regulator
crank case breather pipe, T , pcv
no leak, smoke tested
fuel filter
mass air flow
spark plugs
i'm sure im forgetting some..
boosting 5-6 psi because too lean
unplug the wastegate hose, close the end of the n75
full boost and pulling preaty good !
im chipped at 16 psi by Unitronic .. so id like to have my n75 controlling everything..
17544/P1136/004406 - Fuel Trim: Bank 1 (Add): System too Lean
Possible Solutions
Check Mass Air Flow (MAF) Sensor
Check Fuel Pressure Regulator
Check Fuel Pump
Check Intake/Exhaust System for Leaks
Check Secondary Air Injection for Leaks
Check Vacuum Lines for Leaks
Special Notes
Fuel Trim Info
When this fault is stored and external vacuum leaks are not found, less obvious problems may be present:
Check Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80)
Check Brake Booster and Hoses
Check Electric Vacuum Pump ( If Applicable )
Check Crankcase Ventilation System for faulty components. When the PCV or Crankcase Ventilation System is faulty, vacuum is typically present under the oil cap and misfire faults are common.
please tell me what should i do next .. i do have Vag-com is specific info needed
