Production Solution

Software update for the ECM, J623 (address word 0001).
Service

Perform the following checks:

1. Read the DTC memory of the ECM.

2. Read/assess the measured value with the ODIS measured value identifier IDE09529 "Fuel mass flow

fumigation from engine oil". Warm up the engine at idle speed and observe the above measured value

together with the engine oil temperature. The evaporation process of fuel in the engine oil starts at about

122°F engine oil temperature.

a. If the value of the fuel mass flow is at least intermittently above 75 mg/s, this clearly points to a high fuel

share in the engine oil (over 0.5 l). In this case, the condition is caused by an extreme short distance

operation profile of the customer. We recommend to explain the background to the customer. Update the

ECM with SVM code 01A225.

b. If the limit of 75 mg/s is not exceeded and the condition cannot be reproduced, the driving profile of the

customer before the workshop visit may have completely consumed the fuel in the engine oil. In this case,

we also recommend to enquire about the driving profile of the customer for a possible explanation. In this

case, also update the ECM with SVM code 01A225. An oil change is not necessary.

c. Adjust oil level using T40178 to proper level.

SVM Update Instructions

1. Follow all instructions in TSB 2011732: 00 Software Version Management (SVM), operating instructions.

2. Update the ECM, J623 (address word 0001) using the SVM action code as listed in the table below if

necessary:
