SI B12 24 09
Engine Electrical Systems
October 2009 Technical Service
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL
AFFECTED VEHICLES THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS AND PRIOR TO RETAIL DELIVERY.
SUBJECT
Service Action: Retrofit Oil Level Sensor Ground Strap
MODEL
E82 and E88 vehicles with N51 engines, produced from 4/27/2009 to 8/17/2009
SITUATION
The ground strap between the oil level sensor (QLT) and the bracket for the sensor connector was not fitted during production.
CAUSE
A poor oil level sensor ground connection may lead to implausible measured values for the engine oil level or oil temperature.
AFFECTED VEHICLES
This Service Action involves E82 and E88 vehicles with the N51 engine produced from 4/27/2009 to 8/17/2009.
In order to determine whether a specific vehicle has had this Service Action completed or is affected by this Service Action, first check the B-pillar label for code number 552. If code number 552 has been punched out, the campaign has already been performed. If code number 552 has not been punched out, it will be necessary to utilize the "Service Menu" of DCSnet (Dealer Communication System) or the Key Reader. Based on the response of the system, either proceed with the corrective action or take no further action.
PROCEDURE
Inspect and clean the ground strap contact surfaces, if necessary.
Install one end of the ground strap onto the bracket for the oil level sensor and the other end to the bracket which holds the sensor connector. Torque both bolts to 8 Nm.
