- Not a complete vacuum pump assembly — the pump body, vane, and rotor are not included
What This Part Does
On BMW diesel engines, the vacuum pump is the sole source of vacuum for the brake booster, HVAC airflow control, and turbo actuator systems — diesel engines do not produce intake manifold vacuum naturally. The pump is driven directly off the camshaft and sealed internally with rubber components that degrade under continuous heat and oil exposure.
When the seals wear or harden, the pump begins leaking oil externally and loses the capacity to maintain consistent vacuum pressure. This kit replaces the failed sealing elements, allowing the pump housing to be properly resealed and returned to factory operating condition.

Common Symptoms of Failure
- Oil leak from the vacuum pump area at the rear of the cylinder head
- Burning oil smell from the engine bay
- Hard or inconsistent brake pedal due to loss of brake booster vacuum
- Erratic or weak HVAC airflow control linked to vacuum pressure drop
- Turbo actuator malfunction associated with insufficient vacuum supply
Why Choose This Repair Kit
- Targets the root cause — replaces only the failed sealing components
- High-grade elastomer seals rated for engine oil contact and temperature extremes
- Precision dimensions matched to OEM vacuum pump housing specifications
- Full resealing solution: housing gasket and main O-ring included
- Significantly more cost-effective than sourcing a complete replacement pump
Important Before Ordering
Locate the OEM number stamped on your existing vacuum pump body or identify it via your vehicle's parts catalog. Confirm the number matches one of the compatible references listed above — 11667791232, 11667795142, 11667787366, 11667795143, or 11667786841. Also verify your engine code (M57, M57N, M57N2, M47N, M47N2) and chassis platform against the fitment list. If you are uncertain, contact us with your VIN before ordering.
What vehicles does OEM 11667791232 fit?
OEM 11667791232 is a vacuum pump reference used on BMW M57, M57N, M47N, and M47N2 diesel engines. Affected platforms include the E46, E90, E91, E92, E93 (3 Series), E39, E60, E61 (5 Series), E38, E65, E66 (7 Series), E87 (1 Series), E83 (X3), E53, E70 (X5), and E71 (X6). This repair kit is designed to rebuild the vacuum pump carrying that OEM number and its related variants, including 11667795142 and 11667787366.
Is OEM 11667795142 the same type of part as 11667791232?
Both 11667795142 and 11667791232 are BMW OEM numbers for vacuum pump assemblies within the same M57 / M47 diesel family. They represent variants of the same pump design used across different production periods and platforms. This repair seal kit is compatible with both and provides the correct gasket and O-ring set for rebuilding either unit.
What does the vacuum pump do on a BMW diesel engine?
Diesel engines do not produce intake manifold vacuum naturally, so a dedicated camshaft-driven vacuum pump supplies the vacuum required for the brake booster, HVAC airflow control flaps, and turbo actuator systems. On M57 and M47 engines, this pump is critical for safe braking performance and correct operation of vacuum-controlled components throughout the vehicle.
What symptoms indicate vacuum pump seal failure on a BMW diesel?
The most common signs are an oil leak at the rear of the cylinder head near the vacuum pump, a burning oil smell after driving, and a noticeably harder brake pedal — particularly under repeated braking. Reduced HVAC airflow control response and turbo actuator irregularities are also associated with vacuum pressure loss from worn pump seals.
Is this a complete vacuum pump or a seal repair kit only?
This is a vacuum pump repair seal kit — it is not a complete pump assembly. The kit contains the internal seals, housing gasket, and main O-ring required to rebuild and reseal the existing pump. The pump body, rotor, and vane are not included. The kit is intended for professional rebuild of a serviceable pump where only the sealing elements have failed.
How do I confirm compatibility before ordering?
Check the OEM number stamped directly on your vacuum pump body, or locate it in your vehicle's electronic parts catalog using your VIN. Cross-reference against the compatible numbers: 11667791232, 11667795142, 11667787366, 11667795143, or 11667786841. Confirm your engine code (M57, M57N, M57N2, M47N, M47N2) and chassis platform match the fitment list. If you are unsure, contact us with your VIN before placing an order.
