Q1: Is this a genuine BMW part?

A: The 11667640279 reference is the original equipment part number. Both genuine BMW and aftermarket equivalents (such as Febi Bilstein) are available that match the original fit and function.

Q2: How do I confirm if it fits my vehicle?

A: Check your vehicle's existing part number. If your current vacuum pump is stamped with 11667640279 or the superseded references listed above, this replacement will fit. Also confirm your vehicle is equipped with the N20/N26 engine and that the production date falls within the applicable range for your model, as several applications are production-date sensitive.

Q3: What are the symptoms of a failing brake vacuum pump?

A: Common signs include a hard or stiff brake pedal, reduced braking assistance, oil leaks from the rear of the engine, and a whistling or hissing noise. Because this pump also supplies vacuum to the turbo wastegate actuator, failure can also affect turbo performance.
