VAG Codes for Dummies

[Pankus101]

Hi All - I hope someone can explain this to me in simplified English. I would love to know if any of these issues could be resolved on the cheap, without bringing the car to the dealer and spending a boatload. Got a small neighborhood mechanic to take a look and he read the following codes:

17511-P1103 B1S1 - I googled this, and came up with a sensor heating circuit - but what does that mean and how can I fix that?

17544-P1136 B1 - this came up as a Fuel Trim issue... again, what does that mean in layman's terms and is there an easy fix?

16891-P0507 - Idle Air Control issue..... any easy fixes?

16395-P0011 A. B1 - Something about a Camshaft A....


Another issue which came up recently - the Traction Control light comes on and stays on at times. Sometimes it's nothing but the light, and sometimes I can feel the wheels slipping - various road conditions - wet, dry, uphill, downhill, flat... If the light is on and I hit the brakes, I sometimes feel a strong vibration under my feet.

So, with this in mind, should I just bite the bullet and take it in or is there something I can do to remedy any of these issues? I don't mind getting dirty, I just don't know much about it yet, and haven't really worked on engines myself. Willing to give it a try though!

Thanks guys - I appreciate you taking your time to help a newbie!

17511/P1103/004355 - Oxygen (Lambda) Sensor Heating; B1 S1: Performance too Low
Possible Solutions
Check Oxygen Sensor Heating for Oxygen Sensor before Catalytic Converter

Im guess damaged cable or sensor needs replacing.

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.


16891/P0507/001287 - Idle Control System RPM: Higher than Expected.


Possible Symptoms
Malfunction Indicator Lamp (MIL) active
Possible Causes
Throttle Valve Control Module (J338) dirty/faulty
Wiring/Connector(s) from/to Throttle Valve Control Module (J338)
Vacuum Leak
Possible Solutions
Check Throttle Valve Control Module (J338)
Check Wiring/Connector(s) from/to Throttle Valve Control Module (J338)
Check Intake System for Leaks

16395/P0011/000017 - Bank 1: Camshaft A (Intake): ****** Setpoint not Reached (Over-Advanced)


Possible Symptoms
Power Loss
Possible Causes
Camshaft Adjustment Valve 1 (N205) faulty
Fuel Pump Relay (J17) faulty
Mechanical Timing not correct, including Chain and/or Belt timing.
Possible Solutions
Check Camshaft Adjustment Valve 1 (N205)
Check Fuel Pump Relay (J17)
Check Mechanical Timing



Sounds like some air leaks and possibly the cam belt is a tooth off, has it been recently been changed?
