Revised Customer Statement and Service (Updated SVM Table)

Initial publication
Customer statement:
 The engine sporadically does not start after reaching operating temperature and being parked for longer
stationary periods (engine not completely cooled down). However, the starter motor will turn over normally.
 The engine sporadically does not start or only after long cranking period then runs rough for a few seconds
(starter motor turns normal).
Workshop findings:
 Usually there are no DTCs in engine control module (ECM), J623 (address word 0001).
Or
 Sometimes a DTC about fuel metering system "System too rich" will appear in the engine control module
(ECM), J623 (address word 0001).
Technical Background
Deviation in fuel-air mixture at engine start.

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 change the engine oil and 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.
In addition check the following fuel pressure values:
1. Check the holding pressure of the high and of the low pressure fuel pump (fuel pump for pre-supply G6) at
room temperature (about 64-68°F):
 Warm up the engine to an oil temperature of at least 176°F and read the following measured values:
IDE00186 low fuel pressure, actual value
IDE00188 high fuel pressure, actual value
IDE06212 fuel pressure high-pressure accumulator 2
 Observe the development of the high fuel pressure after switching off the engine (required pressure
development: gradual rise to about 80 bar in 10 minutes). If the pressure development is different, the
cause of the condition can be a leaking high pressure fuel injector. In this case, borescope the combustion
chamber to determine if there is a leak from one of the high pressure fuel injectors.
 Also, observe the pressure build-up of the low fuel pressure after switching off the engine. In the first five
minutes the low pressure must rise above 6 bar and the pressure must be held for another 10 minutes. If
the low fuel pressure was built up correctly but drops by more than 1.5 bar in the first 15 minutes, it can be
assumed that at least one of the high-pressure fuel pumps is leaking. In this case, replace both highpressure fuel pumps and change the engine oil.
