SUBJECT

N63 - Engine Malfunction Warning Due to Vapor Forming in the Fuel System
MODEL

F07, F10, F12, and F13 with the N63 engine produced up to approximately 6/30/2011
SITUATION

The Engine Malfunction warning is displayed and the Service Engine Soon (MIL) Lamp is on.
This situation may occur when starting the engine at operating temperature after a “hot-soak” period. It
is more likely to occur during months with cooler ambient temperatures and winter fuel is available.
The following fault code is stored in the DME.
110001 – Cylinder injection cutout: pressure too low in high-pressure system
And additionally in isolated cases fault:
11A002 – Fuel high-pressure system, fuel pressure: minimum pressure undershot
CAUSE

This problem can occur if vapor forms in the fuel system due to excessive temperatures and fuel quality
characteristics. Areas using winter fuel blends with high ethanol content are perhaps more susceptible in
having this situation to occur.
CORRECTION

Perform the recommended test plan(s) using only the most current version of ISTA/D.
Based upon the results of the test plan(s), if no problem is found and the low side pressure supply is
correct then perform the following repairs.
Replace the fuel pump supply module (refer to SI B16 04 10) and then perform the following conversion
using the latest version of ISTA/P.
Conversion: control fuel feed pressure
This will add the E-Word (KV01) to the vehicle order (VO) and install DME calibration which will
increase the low side supply pressure to 5.9 BAR when necessary to prevent vapor formation.
In addition, further improvements were implemented to reduce under hood temperatures under
certain driving conditions with an optimized auxiliary fan strategy.

Improved Fuel Supply Module (In-tank Electric Fuel Pump)
The fuel supply modules were improved starting in mid-June 2011 production with the parts stock
cleared of the early design parts.
The new supply modules have the improvements needed to ensure long term durability when operated at
an increased output pressure.
This is now the only replacement part available and is identified by the letter “A” at the end of the bar
code / part label (located on top of the part) or by a “Green” dot on the box..
IMPORTANT!
The ISTA/P conversion to increase the fuel feed pressure can only be performed once the latest fuel
supply module has been installed or found to already be installed by the presence of the “A” on the bar
code / part label.
Note: When the ISTA system message displays:
Battery voltage only “XX.XX” V. Please connect charger.
Please note the displayed battery voltage reading in the repair order comments section.

Labor operation code 00 00 006 is a Main labor operation. If you are using a Main labor code for
another repair, use the Plus code labor operation 00 00 556 instead.
Refer to KSD2 for the corresponding flat rate unit (FRU) allowance. Enter the Chassis Number, which
consists of the last 7 digits of the Vehicle Identification Number (VIN). Click on the “Search” button,
and then enter the applicable flat rate labor operation in the FR code field.
If a control module fails to program correctly or initializations are required, the additional work must be
claimed with separate labor operations under the applicable defect code listed above, refer to KSD2.
