Technical Service
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON
ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME
THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
BMW centers must ensure recalls are completed after having been notified by BMW of North America, LLC (BMWNA) that a safety-related defect or noncompliance exists in any motor vehicle or item of replacement equipment in the center's possession at the time of notification. In BMW NA's case, this notification would typically be made by the issuance of a recall notification in the form of a Service Information bulletin (SIB) or transmission of a Dealer Communication System (DCS) recall message.
Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended, if a recall campaign is announced by BMW NA, centers must ensure that all recalls on new vehicles and new items of replacement equipment are completed BEFORE delivery to the consumer. This means that centers may not legally deliver new motor vehicles or new items of replacement equipment to consumers with an open recall.
The Safety Act also prohibits centers from selling or leasing the motor vehicle or item of replacement equipment, unless and until the open recall has been completed BEFORE delivery. This also pertains to vehicles in the Certified Pre-Owned program, and to items of replacement equipment.
Finally, BMW centers should not sell or use parts that have been recalled by BMW NA. Please follow the specific instructions provided by BMW NA on the return or disposition of the parts.
SUBJECT
Recall Campaign 13V-045: Inspect Brake Booster Vacuum Supply Line
MODEL
E70 with N62TU engine
SITUATION
Engine oil may enter the brake booster vacuum supply line via the brake vacuum pump and contaminate the brake booster, which may result in damage to the membrane. In such cases, the membrane can develop leaks which could lead to reduced or no brake power assistance. It is then still possible to slow and stop the vehicle by applying greater force on the brake pedal.
AFFECTED VEHICLES
This Recall Campaign involves the E70 (X5) with the N62TU engine produced from September 2006 to March 2010.
In order to determine whether a specific vehicle has had this Recall Campaign completed or is affected by this Recall Campaign, first check the B-pillar label for code number 642. If code number 642 has been punched out, the campaign has already been performed. If code number 642 has not been punched out, 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
The updated brake booster vacuum supply line with a fluid check valve is to be installed in all applicable vehicles to eliminate future contamination. If oil contamination is found during the inspection, the brake master cylinder and brake booster must be replaced as well.
1. Remove the brake booster vacuum supply line/pipe (3) together with the non-return valve (2) from the brake booster (1).
2. Check the brake booster vacuum supply line/pipe at the nonreturn valve upstream from the brake booster for oil contamination. Insert a tightly rolled-up comer of a non-reusable lint-free white shop towel (see arrow) into the non-return valve (2). If the towel does not indicate any engine oil residue, proceed to step 4.
3. If the non-return connection exhibits contamination with engine oil proceed to step 5.
4. Replace the following components only if oil contamination is NOT found. Refer to the applicable parts list.
^ Vacuum supply lines/pipes; clamp.
^ Seal for brake booster
^ Intake manifold gaskets
Refer to Repair Instruction 11 66 000, "Removing and installing vacuum pump (vacuum line/pipe and clamp installation)" and 11 61 050 "Removing and installing intake plenum/manifold." The vacuum supply lines/pipes are routed under the intake manifold.
5. Replace the following components only if oil contamination is found. Refer to the applicable parts list.
^ Brake master cylinder and O-ring
Refer to Repair Instruction REP 34 31 505, "Removing and installing or replacing brake master cylinder."
^ Brake servo unit; brake booster seal/gasket and circlip
Refer to Repair Instruction REP 34 33 505, "Removing and installing or replacing brake booster."
^ Vacuum supply lines/pipes; clamp and seal for brake booster
Refer to Repair Instruction REP 11 66 000, "Removing and installing vacuum pump (vacuum line/pipe and clamp installation)" and 11 61 050 "Removing and installing intake plenum/manifold." The vacuum supply lines/pipes are routed under the intake manifold.
PARTS INFORMATION
Use the parts described only if oil contamination is NOT found during the inspection, as directed in step 4.
Use the parts described only if oil contamination is found during the inspection, as directed in step 5.
IMPORTANT:
Prior to the brake booster installation, make sure that all transportation packaging materials (e.g., yellow foam securing the push-rod inside the booster cavity) are removed.
LABEL INSTRUCTIONS
If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on top of another one, because a number from an underlying label could appear in the punched-out hole of the new label.
