VANOS Adjuster, Exhaust, BMW - F22, F3X, F10, X1/X3/X4/Z4 28i (N20/N26)

This part is listed by BMW as BMW part number 11367583819 (11 36 7 583 819) and is described as the exhaust cam VANOS adjuster unit for N20 and N26 engines. This exhaust adjuster fits to F22 228i, F30 320i/328i, F32 428i, F10 528i, and X1/X3/X4/Z4 28i models. This is the adjuster unit that rotates the exhaust camshaft during normal VANOS operation. A failure of the adjuster will cause the camshaft to be fixed in one position, or may have a delayed reaction, affecting performance and drivability.

The N20 VANOS system is made up of several components, all of which could give you VANOS issues (power loss, rough running, poor fuel economy, slow starting, rattle noises, and check engine faults). This adjuster unit works with the N20 solenoid actuator, central valve, sensor wheel, and the oil system itself. There are multiple tests that can be run with advanced diagnostic equipment to determine which of the components is at fault. It's vital that you have the problem(s) correctly diagnosed beforehand to avoid costly extra work and frustration.

This is a Genuine BMW VANOS adjuster with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
