SUBJECT

Voluntary Emissions Recall Campaign 10E-A02: N54 High-Pressure Fuel Pump (HDP)

MODEL

E60, E61, E71, E82, E88, E89, E90, E92, and E93 with the N54 engine produced from 05/26/2006 through 12/21/2009

SITUATION

An internal component in the high-pressure pump (HDP) may fail, causing drivability symptoms such as longer starting times or erratic engine

2010 BMW 335Cic Convertible (E93) L6-3.0L Turbo (N54) 121

operation. Should this situation occur, the engine emergency operation (Safe Mode) is activated and the Service Engine Soon lamp (MIL) is

illuminated.

Note:

In this situation, the vehicle can continue to be driven, even for long distances, without the risk of a breakdown.

The low-pressure fuel sensor may deteriorate prematurely due to internal leakage. The Service Engine Soon lamp (MIL) may be illuminated with the

appropriate fault code stored in the DME fault memory.

Copy of the customer notification letter is shown in this bulletin .

AFFECTED VEHICLES

This Emissions Recall Campaign involves E60, E61, E71, E82, E88, E89, E90, E92, and E93 vehicles with N54 engines which were produced from

05/26/2006 through 12/21/2009.

In order to determine whether a specific vehicle has had this Emissions Recall Campaign completed or is affected by this Recall Campaign, it will be

necessary to utilize the "Service Menu" of DCSnet (Dealer Communication System) or the Key Reader. Based on the response of the system either

proceed with the corrective action or take no further action.

CORRECTION

Read vehicle's fault memory using the current version of ISTA/D. Check, and if required, replace the low-pressure fuel sensor and the high-pressure

fuel pump (HDP).

NOTE:

E89 (Z4) vehicles are not equipped with the low-pressure fuel sensor. A fault memory/low-pressure sensor check should not be performed on E89

vehicles.

PROCEDURE

1. Use the current ISTA diagnosis software (2.22 or higher). Perform the vehicle test and read the fault memory.

Note:

This step does not need to be performed on E89 vehicles.

2. If any of the following low-pressure sensor fault codes (29F3, 2A2D, 119201, 119202, 11A201, 11A202, 11B211) are stored in the DME, replace

the low-pressure fuel sensor. Follow Repair Instruction REP 13 53 594. Clear the fault memory and continue to step 6.

3. If only fault codes 2FBF or 11A401 (Fuel pressure on-release injection; pressure too low) or no faults were stored in the DME memory, go to step

4.

4. Activate the electric fuel pump (EKP) for 20 seconds using ISTA/D 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).

5. If the low fuel pressure exceeds 6.7 bar at any time during the measurement period, replace the low-pressure fuel sensor. Follow Repair

Instruction REP 13 53 594.

If the fuel pressure stays below 6.7 bar, the low-pressure sensor is operating correctly and does not require replacement.

Clear fault memory and continue to step 6.

6. [NEW] Verify the DCSnet vehicle repair history. If the high-pressure pump was recently replaced with P/N 13 51 7 613 933, 13 51 7 594 943 or

with its supersession P/N 13 51 7 616 170, no more action is required.

7. [NEW] If the HDP was not replaced previously with P/N 13 51 7 613 933, 13 51 7 594 943 or P/N 13 51 7 616 170, install new high-pressure

fuel pump P/N 13 51 7 616 446. Follow Repair Instruction REP 13 51 017.

Important:

Repair Instructions 13 51 017 and 13 53 594 have been updated with the release of 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 (or low-pressure fuel sensor) on the N54 engine (for more details, refer to SI B13 10 10).

IMPORTANT NOTE:

All three part numbers (P/N 13 51 7 613 933, P/N 13 51 7 616 170 and P/N 13 51 7 616 446) incorporate the same level of HDP quality

2010 BMW 335Cic Convertible (E93) L6-3.0L Turbo (N54) 122

improvements. If necessary, in order to expedite the repair time, you may use P/N 13 51 7 613 933 or P/N 13 51 7 616 170 from your center's parts

stock supply. This may be done only for individual, time-critical cases. For regularly scheduled campaign repairs, P/N 13 51 7 616 446 should be

ordered from the PDC.

PARTS INFORMATION

LABEL INSTRUCTIONS

After the vehicle has been checked and corrected, obtain a label (SD 92-406) and with a ball point pen print your dealer code (5 digits) on the Recall

Completion Label (see illustration). An initial quantity of 200 labels will be sent to all BMW centers. Peel the label from its backing and affix it to

the right (passenger) rear side of the hood in the engine compartment, close to windshield.

For California centers only: It is required by the California Code of Regulations that an executed orange "Vehicle Emission Recall - Proof of

Correction" certificate (SD92-084, see illustration) be provided to each customer (for vehicles registered in the state of California), once the Recall

on his or her vehicle has been completed.

Note:

Additional labels can be ordered online at BMW TIS.
