Vanos Unit with Solenoid - Rebuilt - S54 - E46 M3, Z3M, Z4M

Part #: 11367838161R

The E46 M3, the Z3 M Coupe/Roadster and the E85/86 MZ4 Coupe/Roadster all came equipped with the S54 engine which was a much more complex engine than the earlier US Spec M3 had. The vanos on the S54 also evolved into a more complex unit and has it's own set of inherent problems that many S54 owners will run into eventually. The S54 Vanos controls both the intake and exhaust camshafts to improve performance, torque, idle characteristics and emissions. A high pressure (1200psi) control system is used to ensure responsive and accurate camshaft adjustments required by the high performance M engine. The back of the vanos houses a radial oil pump to produce the 1200psi of oil pressure. This pump is mechanically driven by a hub on the exhaust camshaft, which is one of the common failure points on this engine. The vanos also uses 4 solenoids which are attahed to the bottom of the unit in a non-rebuildable aluminum case. These solenoids are very sensitive to oil pressure and can easily become clogged or damaged over time due to contaminates in the oil. We highly recommend changing the oil every 5000 miles and only using the BMW 10w60 High Performance oil to prolong the life of the vanos. Typically the S54 vanos does not exhibit the common diesel rattle under normal operation. If you notice that your engine has suddenly become noisy we recommomend that the car not be driven any more than necessary until the source of the noise can be determined. This S54 vanos comes fully rebuilt with brand new solenoids and solenoid valves. This is the exact same package the dealers sells, but at half the cost.
