SUBJECT

Engine Low Oil Level Warning With Ignition Off

SITUATION

In certain instances the customer may complain of the low oil level light on or a low oil level message in the check control after the ignition has been turned off. Checking the oil level with the dipstick shows the correct oil level.

IMPORTANT: For the complaint of "low oil level message displayed while driving, on X5 4.4 up to 10/02 production", refer to Service Measure B11 200 04 (January '04).

CAUSE I

Coding data error in Light Check Module IV (LCM IV).

CAUSE II

The oil level sensor has been contaminated, reducing the capability of the sensor to accurately determine oil level.

CORRECTION FOR CAUSE I

On a customer complaint basis only, recode the LCM module with DIS CD 34, or higher.

CORRECTION FOR CAUSE II

On a customer complaint basis only, replace the oil level sensor and refill engine with fresh oil.

PROCEDURE II

Ensure the engine is warm. Loosen oil filter cover to allow engine oil to drain into oil pan. Raise vehicle on hoist. Remove any underbody paneling or reinforcement as necessary to gain access to the sensor. Drain the oil. Disconnect the plug connection (1) and unscrew the three nuts (2) fastening the sensor to the oil pan. Clean the sealing surface of the oil pan in the location of the sensor. Replace the sensor and gasket ring with new parts. Reinstall the underbody paneling or reinforcement and lower vehicle. Tighten the oil filter housing cover and refill crankcase to proper level with new oil. Do not reuse the original oil!
