Original BMW Cylinder Head to VANOS Oil Flow Regulating Valve for E46 M3 (2001–2006), Z3 M Coupe and Roadster (2001–2002), and Z4 M Coupe and Roadster (2006–2008)

The Original BMW VANOS oil regulating valve, part 11-36-7-830-341, controls oil flow from the cylinder head to the VANOS unit on the S54 inline six in the BMW M3, Z3 M, and Z4 M. BMW calls it simply a regulating valve. It mounts between the cylinder head and the VANOS unit and meters the oil that the variable cam timing system depends on. The valve is a small, light part at 50 grams, and it comes as a complete single valve with its seals. BMW has produced this number since July 2000, which covers every model year in the fitment for this part.

Original BMW Parts carry a 24-month parts warranty.

One number covers every S54 application in BMW's parts data, so there is no early, late, left, or right version to sort out. BMW assigns the same regulating valve to the E46 M3 coupe and convertible, the M3 CSL, the Z3 M3.2, and the E85 roadster and E86 coupe Z4 M3.2. On any engine with variable cam timing, the camshaft adjusters are moved by engine oil, which is why the parts that feed that oil sit right at the cylinder head. On the S54, this valve is the first stop for the oil headed to the VANOS hardware, ahead of the high-pressure pump and the adjusters.

Common Questions

Is this valve a common failure item on the S54?
It is generally not a failure point. It may need replacement when diagnosis shows that inadequate oil flow to the VANOS unit is causing a performance problem.

What does this valve feed?
It regulates oil to the VANOS unit, where the VANOS high-pressure pump needs that supply. The pump itself is driven off the exhaust camshaft.

Do I need to buy O-rings separately?
No. Both sealing O-rings, 11-41-1-306-082 and 11-31-1-317-318, come with the valve.
