Validity
Model 166, 222 with engine 642.8
Reason for change
Reason for block
Complaint:
Intermittently reduced power. After an ignition cycle, the complaint is no longer reproducible.
a) No warning was displayed in the instrument cluster and no faults are logged in the engine control unit (N3/9) in the
quick test.
b) The engine diagnosis warning lamp was activated and faults including some referring to the exhaust back pressure
sensor (B60) are logged in the quick test. For relevant fault codes see 'Control unit/ fault code'.
Cause:
Intermittent transition resistances in the wiring harness at the crimp connections of the female contacts.
Remedy:
If all the test steps stored in Xentry Diagnostics have been performed and no component faults were found, the following work must be carried out:
-Visually inspect contacts at engine control unit (N3/9) connector
M+F.
- Visually inspect connections/ female contacts of relevant sensors for which faults are logged.
If no noticeable problems are found, perform the following work:
If no faults were logged under the engine control unit (N3/9) in the quick test, read out the fault codes without status
filter. (Xentry Diagnostics => Engine control unit (N3/9) => Special processes => 'Display all fault codes without status
filter')
- For faults in the differential pressure sensor (B28/8): Install repair wiring harness (see Parts) using solder connectors. For this, refer to WIS document AR00.19-P-0100-09A!
- For faults in the exhaust back pressure sensor (B60): Replace female contacts (see Parts) of connector on sensor.
- For faults in the high-pressure fuel pressure sensor (B4/6): Replace female contacts (see Parts) of connector on
sensor.

Contact spray must never be used on contacts on the engine wiring harness. The use of contact cleaners can cause
consequential damage!
If the fault reoccurs, please Open a PTSS case and provide Copy of the Quick Test, Copy of "Display all fault codes
without status filter", test steps performed with parts numbers replaced.
