VAG Error Code: 16689/000773
EOBD II Error Code: P0305

Fault Location:
Cylinder 5 - Misfire Detected

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Lack/loss of power.
Hard start.
Engine hesitation.

Wiring/Connector(s).
Ignition system.
Fuel injectors.
Fuel pressure.
Running out of fuel.

Engine Control Module (ECM) damaged.

Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Do a compression test.
Read Measuring Value Blocks (MVB) 15 if misfire changes location.

Special Notes:
This feature search for engine misfire in a specific cylinder. Most of the time the cause for a misfire is a lack of combustion in a cylinder due to absence of spark, poor fuel metering, or poor compression.

Tech Notes:
The P0305 code means that the cylinder 5 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 5. If the problem persist more tests needs to be done to diagnose problem.

Description:
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Engine Speed (RPM) Sensor (G28)/Crankshaft Position Sensor (G28) signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.
