Complaint:
Check engine light with some or all the following DTCs relating to the cooling / vacuum systems.

- P003313 - "The output for the switchover valve of bypass flap 'Charge air' has an electrical fault. There is an open

circuit."

- P0299FA - "The boost pressure of turbocharger 1 is too low."

- P0299FB - "The boost pressure of turbocharger 1 is too low."

- P226100 - "The bypass flap 'Charge air' has a mechanical malfunction."

Remedy:
1- Inspect the vacuum system for loose connections or cracked hoses (See Vacuum Diagram)

-Yellow color -> part #9 --> connection point behind the coolant pump bracket

-Green color --> part #14 --> vacuum reservoir

2- Smoke test or pressurize the system to detect a leak especially in the following known areas

-Water pump mounting plate

-Vacuum connection on water pump mounting plate

-Water pump O-ring

-Water pump vacuum line

-Water pump

-Vacuum manifold / Vacuum reservoir

Note: ONLY USE LOW PRESSURE MAXIMUM 1BAR / 14.7psi TO AVOID DAMAGES

3- Remove vacuum hoses from vacuum reservoir and look for the following

- Particulate matter

- Contamination of the inside of the vacuum connection

- Any signs of coolant and / or oil on the inside of vacuum connections on the vacuum reservoir

Note:

The vacuum reservoir is a sealed unit. Pictures attached show internal contamination of the vacuum reservoirs. The

vacuum reservoirs were cut open for informational purposes only. DO NOT cut open the vacuum reservoir.

-Perform all Diagnostic procedure before replacing any parts.

4 - If coolant is found in the vacuum system replace the water pump, vacuum reservoir and clean the vacuum lines.
