Our solutions are characterized by their simple interpretation. They include demonstrative images and are arranged in four fields: Error codes, symptom, cause and solution.

HIGHLIGHT NEWSLETTER

CAR

VW SCIROCCO (137) 2.0 TSI

SYSTEM

PETROL ENGINE - MECHANICS

ERROR CODES

00022-P0016 - Bank 1, Camshaft position sensor (G40) or crankshaft sensor (G28). Incorrect correlation.

SYMPTOM

Fault code recorded in the engine control unit.


The vehicle displays one or several of the following symptoms:

- Squeaking, rattling or jingling noises coming from the front part of the vehicle.
- Engine does not start.
- Engine warning light (MIL) ON.


NOTE: The above-mentioned symptom appears again when starting the engine.


NOTE: This technical note affects only those vehicles that are within a specific VIN (vehicle identification number) range.

CAUSE

Malfunction of the timing chain tensioner.

SOLUTION

Repair procedure:

- Read the fault codes recorded in the engine control unit using the diagnostic tool.

- Confirm that the fault code is the same as the one that appears in the field symptoms of this bulletin.

- Confirm that the symptoms that appear in the field symptoms of this bulletin are reproduced.

- Check the version of the timing chain tensioner.



If the sensor is the same as the one in image 1:

- Check the piston and valves, check if the piston of the tensioner can be pressed in by hand.

- Replace the engine if the valves and pistons have touched each other.

- Replace the tensioner and the timing chain with a modified version if the sensor is the same as the one in image 1.



If the sensor is the same as the one in image 2:

- Check the camshaft bearing and the inlet camshaft if the piston of the tensioner cannot be pressed in by hand.

- Replace the cylinder head if there is damage in the camshaft bearing or inlet camshaft.

- Replace the timing chain if the sensor is the same as the one in image 2.

- Carry out an oil and filter change.

- Clear the fault codes recorded in the engine control unit using the diagnostic tool.

- Carry out a second fault code reading of the engine control unit (ECU) using the diagnostic tool and confirm that NO fault codes are recorded.



Bear in mind the following:

- Remove the engine block.

- Check the condition of the retention valve.

- If it is broken, replace and remove any possible pieces of the valve from the lubricant circuit.


NOTE: The manufacturing date of the vehicle indicates which is the replacement of the correct part available for this application.
