SUBJECT
N54: Diagnosis for DME FC 29DC/29F2/2FBF and Extended High-pressure Fuel Pump (HDP) Warranty

Coverage

MODEL
E90, E92 with N54 produced from 06/06

E93, E60, E61 with N54 produced from 03/07

E82, E88 with N54 from start of production

E71, X6 with N54 from start of production

E89, Z4 with N54 from start of production

F01, F02 with N54 from start of production

SITUATION I
The customer may complain of:


Excessive cranking time before the engine starts (5-6 seconds) on a cold start or after a hot soak.
In most cases, diagnosis shows fault code 2FBF as the only fault stored in the DME with SES lamp illumination.

SITUATION II
The customer may complain of the following:


“Vehicle loses power while driving” or “Vehicle runs poorly”.

The Service Engine Soon lamp may be illuminated.
Diagnosis shows fault code 29DC (Cylinder injection cut-out, pressure too low in high-pressure system) and/or

2FBF (Fuel pressure on-release injection, pressure too low), and in some cases, also in conjunction with 29F1

(Fuel high-pressure, plausibility) and 29F2 (Fuel high-pressure, fuel pressure undershot).

In some cases, misfire faults for various cylinders (e.g., FC 20D1, 29CF, 29D2, 29CE, 29D0, 29CC) are also

stored in MSD80/MSD81.

CAUSE
Possible causes may include:


Sensitivity of injection pump (HDP) diagnostic software


Internal failure of a High-pressure Injection Pump (HDP)

Failure of an electric fuel pump or a clogged fuel filter

Failure of the low or high-pressure sensors

Defective fuel pressure check - valve/fuel pressure regulator

Failure of a volume control valve

Defective fuel injector

Intermittent electrical connection problem (wire and/or connector) in the fuel delivery system.
CORRECTION FOR SITUATION I
For E90, E92, E93, E60, E61, E82, E88, and E71 vehicles where the customer complains of “Long Cranking

Time” and fault code 2FBF is stored in the DME with the SES illuminated, proceed as follows:

1. Use the current ISTA diagnosis software (2.22 or higher).

2. While observing the fuel pressure, activate the electric fuel pump for 20 seconds, using ISTA and the

diagnostic query function (after the vehicle test, select Control unit tree; DME; Call ECU functions;

Diagnostic query; and Low pressure fuel pump with activation).

3. Immediately after electric pump activation, the pressure must reach at least 4.75 bars.

4. If the minimum threshold of 4.75 bars was not reached, further diagnose the low-pressure system using test

module B1214_DI KDR, Fuel Pressure Control (possibly defective electric fuel pump or fuel filter/pressure

regulator).

5. If the minimum threshold of 4.75 bars was reached, reprogram the vehicle with the current ISTA P version

(ISTA/P 2.40.2 or higher). The target integration levels should be:

E90, E92 and E93 – E89x-10-12-503 or higher

E60 and E61 – E060-10-12-501 or higher

E82 and E88 – E89x-10-12-503 or higher

E71 – E070-12-501 or higher

6. IMPORTANT:

When programming vehicles equipped with the MSD81 DME, make sure that the DME control module is

marked for programming in the measure plan (yellow mark in the control module tree and a “P” symbol).

If the DME is not marked, you have to select it manually for programming in the control module tree (click

on the module and mark the “program” checkbox), and then determine the measures plan.

7. After programming the DME programmed number should be “7626000” or higher.

8. After programming, readapting the DME by means of a short test drive is recommended:


Bring the engine to the normal operating temperature.

Page 3 of 9

Drive the vehicle at a speed of between 50-60 mph and engine speeds of 2,000-3,000 rpm for

approximately 3 minutes (use manual gear shifting, if needed).

Let the engine idle for approximately 5 minutes.

If possible, to confirm repair effectiveness, let the vehicle sit overnight and cold start it the next

morning. Then let it idle for approximately 5 minutes.
For E89 vehicles where the customer complains of “Long Cranking Time” and only the fault code 2FBF is

stored in the DME with the SES illuminated, proceed as follows:
1. Install a calibrated manual fuel pressure gauge

(e.g., P/N 83 30 0 491 260 pressure gauge from

the K-L-Jetronic special tool kit P/N 83 30 0

491 259), connected with the three-way adapter

tool 135 270, into the low-pressure fuel supply

line as follows:

#1 – Three-way adapter tool (135 270)

#2 – Pressure gauge P/N 83 30 0 491 260

2. Use the current ISTA diagnosis software (2.22 or higher).

3. While observing the fuel pressure on the gauge, activate the electric fuel pump for 20 seconds, using ISTA

and the component activation function (after the vehicle test, select Control unit tree; DME; Call ECU

functions; Component activation; and Fuel pump).

4. Immediately after electric pump activation, the pressure read from the manual gauge must reach at least

4.75 bars.

5. If the minimum threshold of 4.75 bars was not reached, further diagnose the low-pressure system using test

module B1214_DI KDR, Fuel Pressure Control (possibly defective electric fuel pump or fuel filter/pressure

regulator).

6. If the minimum threshold of 4.75 bars was reached, reprogram the vehicle with ISTA/P 2.40.2 (or higher).

The target integration level should be E89x-10-12-503 or higher

After programming, readapting the DME by means of a short test drive is recommended:


Bring the engine to the normal operating temperature.

Drive the vehicle at a speed of between 50-60 mph and engine speeds of 2,000-3,000 rpm for

approximately 3 minutes (use manual gear shifting, if needed).

Let the engine idle for approximately 5 minutes.

If possible, to confirm repair effectiveness, let the vehicle sit overnight and cold start it the next

morning. Then let it idle for approximately 5 minutes.
CORRECTION FOR SITUATION II

Page 4 of 9
For E90, E92, E93, E60, E61, E82, E88, E89, and E71 vehicles where the customer complains of “Losing

power when driving”, fault codes 29DC/2FBF and/or 29F1/29F2 are stored in the DME with the SES

illuminated; proceed as follows:

1. Use the current ISTA diagnosis software. Perform test module B1214_DI KDR (Fuel Pressure Control).
2. IMPORTANT: perform this step ONLY

FOR E89 (Z4) vehicles (not equipped with

the low fuel pressure system sensor):

Prior to execution of the High-pressure test

module, install a calibrated manual fuel pressure

gauge (e.g., P/N 83 30 0 491 260 pressure gauge

from the K-L-Jetronic special tool kit P/N 83 30

0 491 259), connected with the three-way

adapter tool 135 270, into the low-pressure fuel

supply line as follows:

#1. – Three-way adapter tool (135 270)

#2. – Pressure gauge P/N 83 30 0 491 260

3. Perform all applicable steps of the High-pressure Fuel test module B1214_DI KDR. Pay attention to all

questions being displayed during diagnosis and answer them correctly. Important Note:

Important Note:

When comparing the measured fuel pressure with the engine running at idle speed, make sure to let the fuel

pressure stabilize for approximately 60 seconds prior to the final reading. Otherwise, an implausible value

(around 150 bars) is going to be entered into the test, resulting in inaccurate diagnosis (defective highpressure pump).

4. After completion of all diagnostic steps, end the test module and enter the “fault feedback” screen. Enter the

result of a diagnosis process into the Diagnosis Code dialog box and obtain a “Diagnostic Code”. In case no

failure can be currently detected in the high-pressure fuel system, enter the last option “No fault found” into

the dialog box.

IMPORTANT DIAGNOSTIC HINT:

In certain cases, the HDP fault may be reproduced only when the engine is under load. In order to replicate

the complaint, it may be necessary to road-test vehicle with the manual fuel pressure gauge installed. The

excessive low-pressure fuel fluctuation (between 5.0 and 7.0 bars) would indicate incorrect operation of the

fuel delivery system.

5.
For additional comprehensive N54 drivability diagnostic information, refer to the “N54 Engine

Diagnostic Fault Tree” (the current version “05_03_13” is attached to this bulletin).
6. Make sure that FASTA data is transmitted after the completion of all appropriate test modules.

7. IMPORTANT:

Starting on November 1st, 2010, TC authorization is NOT required for the HDP pump replacement. For

details related to the “N54 Fuel System TC Action”, refer to SI B13 08 09.

8. If the High-pressure Fuel Pump needs to be replaced, use the updated part P/N 13 51 7 613 933, which

incorporates the latest improvements to internal sealing. For the pump replacement procedure, refer to REP

13 51 017.

Note:

The repair instructions have been updated with the release of the special tool P/N 83 30 0 496 939. The

special tool accommodates easy removal of the engine harness block, located under the intake manifold.

Consequently, the removal of the intake manifold is no longer necessary when replacing the HDP on the

N54 engine.

9. After replacement, clear the adaptation values of the high-pressure flow control valve in the DME by

selecting the path:


Activities / Service Functions

Drive

Motor Electronics

Adjustment Programs

Delete Adaptations / variants, and then Test plan

Reset adaptive values.
10. IMPORTANT NOTE:

In addition, vehicles which have had the HDP pump replaced have to be reprogrammed afterwards with

ISTA/P 2.40.2 (or higher). The target integration levels should be:

E60 and E61 – E060-10-12-501 or higher

E82, E88, E89, E90, E92, and E93 – E89x-10-12-503 or higher

E71 – E070-10-12-501 or higher

IMPORTANT:

When programming vehicles equipped with the MSD81 DME, make sure that the DME control module is

marked for programming in the measure plan (yellow mark in the control module tree and a “P” symbol).

If the DME is not marked, you have to select it manually for programming in the control module tree (click

on the module and mark the “program” checkbox), and then determine the measures plan. After

programming, the DME programmed number should be “7626000” or higher.

11. After programming, readapting the DME by means of a short test drive is recommended:
