Campaign No. 2005060019
September 2005
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT:
MODELS 215/220 WITH ENGINE 137, MODEL YEAR 2000 - 2002
INSPECT, IF NECESSARY REPLACE CYLINDER SHUTOFF OIL PRESSURE SENSOR
This Service Campaign has been initiated because DCAG has determined that on the affected vehicles (see VIN range shown) the oil pressure sensor for cylinder shutoff may leak. Dealer will check the oil pressure sensor for affected date code and replace if necessary.
Prior to performing this Service Campaign:
^ Please check VMI to insure the vehicle is involved and to determine if the vehicle has been previously repaired.
^ Please review the entire Service Campaign bulletin.
Approximately 4,362 vehicles are affected.
Procedure
1. Check oil pressure sensor (arrow, Figure 1 [B40/2]):
^ If color coding (paint mark) is present and oil sensor is not leaking additional work is not required.
^ If color coding is not present continue with procedure.
2. Disconnect cable tie mounting clip (A, Figure 1) from coolant pipe.
3. Disconnect oil pressure sensor connector (arrow, Figure 2) from oil pressure sensor.
4. Remove oil pressure sensor (arrow, Figure 1). Use Special Tool 000 589 72 03 00 or equivalent shown.
5. Replace oil pressure sensors that leak or sensors with manufacturing date code number prior to date code 1291 (refer to note below) with new pressure sensor (arrow, Figure 3).
Note:
^ If removed oil pressure sensor does not require replacement (as described in step 5), reinstall sensor along with new seal ring.
^ Date code explanation: Date code "3243": First 3 nos. (324) represent the 324th day. Last no. (3) represents the year (2003)
6. After installing new oil pressure sensor, mark new sensor with a white paint mark in clearly visible (clean) location.
7. If oil is present on surrounding attached engine components (engine wiring harness, control modules, sensors or ignition modules) due to a leaky oil pressure sensor, replace the affected components (if necessary) and return them for inspection.
8. Perform quick test, delete fault memory, start engine and check for leaks (from sensor).
