20-16-01 Fuel Tank Hard to Fill in Temperatures Below Freezing
Wels Tans Code
Condensation build up in the fuel filler neck vent line causes blockage or restriction
not allowing fuel vapors to vent. Inspect fuel tank vent tube for debris, water and/or
ice. Backlighting the tube with a flashlight or using a bore scope will aid in
diagnosis.

37-16-01 Mechatronics unit or Transmission replacement tips (including DTC
P309D) after the KO Clutch Line is Opened for Service
Teas Tons Cole
Jetta Hybrid 2013-2016 All
When replacing a mechatronics unit or transmission on a Jetta Hybrid, be sure to
remove the plastic shipping plugs from the KO clutch actuator, located on top of
the mechatronics unit and install the aluminum triple square cap from the
component being replaced.
If this cap is not transferred, fault code P309D can set in the TCM.

If the KO aluminum cap was transferred over and P309D sets, or if there are issues
with the Guided Functions KO clutch bleed, be sure the following steps have been
completed:

« All faults have been cleared through Vehicle OBD
¢ Parking brake is in the “OFF” position
« All 4 passenger doors and hood remain closed during the basic settings
¢ Trunk is “Open” with a battery maintainer installed on the 12v battery
After the above steps have been completed, the first step of the KO bleed test can
performed through; AWO1 ECM> Guided Functions> Bleed Disengaging Clutch>
then select option (1) Ventilation and follow the Guided Functions steps in the test
plan.

This step should take approximate 17 minutes to complete. Once the test completes
the test plan will usually exit out to the main control module OBD screen of ODIS.
Once this happens, the second step of the KO bleed test needs to be performed
through; AWO1 ECM> Guided Functions> Bleed Disengaging Clutch> then select
option (2) Air Entrapment and follow the Guided Functions steps in the test plan.

Engines
Due to high load on the sintered cam which drives the high pressure fuel injection
pump and the vacuum pump in the affected vehicles, the camshaft lobe has the
potential to unexpectedly shear off from the camshaft. If this happens, vacuum
pump power will be lost so that the pump will not deliver further vacuum supply to
the brake booster, and reduced engine power (limp home mode) will cause the
Malfunction Indicator Light (MIL) to come on.
Unexpected, increased need for braking effort after vacuum reserve has been
depleted can lead to a crash without warning.

Certain
2009 All All TBD TBD
Routans
Affected vehicles may experience an Occupant Restraint Control (ORC) module
malfunction due to corrosion of the power supply integrated circuit. This could result
in an illuminated airbag warning light with the possibility of no airbag deployment
in a crash necessitating airbag deployment or an inadvertent airbag deployment
without an illuminated airbag warning light. Either of these conditions could
increase the risk of a crash and/or injury to front seat vehicle occupants.
