SUBJECT
N51 Engine: Service Engine Soon Lamp Illuminated - Loss of Power and Various Faults Stored in the
DME
MODEL
.

E88 (1 Series Convertible)
E90 (3 Series Sedan)
E92 (3 Series Coupe)
E93 (3 Series Convertible)
All vehicles produced to 6/2011
SITUATION
The customer complains that the Service Engine Soon lamp is illuminated. The vehicle has lost power; the engine
cranks but will not start; and various faults are stored in the DME for engine misfire and/or mixture adaptations.
CAUSE
The vehicle has lost fuel system delivery pressure due to a loose or split fuel line inside the fuel tank. The failure
is related to an unfavorable stacking of tolerances between the rubber fuel hose and the plastic regulator nipple or
deterioration of the rubber hose construction material.
PROCEDURE
1. Check the fuel pressure as per Repair Instruction REP 13 31 029 Checking the fuel pump delivery pressure.
2. If no fuel pressure is present then
remove the right side fuel tank
access cover to inspect the fuel
hose (1) for disconnection or
damage. Refer to Repair
Instruction REP 16 14 010
Removing and installing the fuel
pump.

the fuel tank for the hose
inspection.
3. Inspect the fuel hose connection
(1) on the pressure regulator (2).
If the fuel hose is found to be
disconnected from the fuel
pressure regulator, replace the
fuel tank. Do not attempt to
replace or re-secure the fuel hose
inside the fuel tank.
4. Inspect the fuel hose (1) for
splitting. It might be necessary to
inspect the entire circumference
of the fuel hose with a small
mirror. If the fuel hose (1) is
found to be split, replace the fuel
tank. Do not attempt to replace
or re-secure the fuel hose inside
the fuel tank.
5. If neither of these conditions is found, continue diagnosis using the available ISTA/D test plans for the
faults stored in the DME before submitting a DMTL System TC case.
Note: TeileClearing authorization is not required for the fuel tank replacement procedure described in this bulletin.
Please write in the comment section of the warranty claim: "Replaced per SI B12 21 10".

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.
Even though work time labor operation code 16 99 000 ends in “000,” it is not considered a Main labor operation.
Also, since the “work time” FRU allowance to be claimed is specified, a separate punch time is not required.
Other Repairs
If performing ISTA diagnostics and related test plans results in other eligible and covered work, claim this work
with the applicable defect code and/or labor operations listed in KSD2.
