BMW Single VANOS Solenoid / Camshaft Adjuster Valve — 11361703720

Restore proper VANOS operation and variable camshaft timing with a replacement BMW VANOS Solenoid / Camshaft Adjuster Valve. This solenoid threads directly into the VANOS unit and controls the flow of pressurized engine oil used to adjust camshaft timing.

The VANOS solenoid essentially functions as an electrically controlled on/off valve. When commanded by the engine management system, the solenoid opens or closes an oil passage inside the VANOS unit. This directs oil pressure to the VANOS mechanism, allowing the system to alter camshaft timing based on engine speed and operating conditions.

As these vehicles accumulate mileage, VANOS solenoids can become weak, stick, or fail electrically. A failed solenoid can prevent the VANOS system from operating correctly, resulting in fault codes and noticeable changes in engine performance.

How Does the VANOS Solenoid Work?

BMW's Single VANOS system uses engine oil pressure to mechanically change the position of the intake camshaft relative to the crankshaft.

The VANOS solenoid controls an internal oil passage within the VANOS unit. When the engine computer energizes the solenoid, it changes the oil flow through the VANOS assembly, allowing the system to advance or retard the camshaft as required.

Unlike later continuously variable VANOS systems, this early Single VANOS solenoid operates essentially as an on/off control valve.

If the solenoid does not actuate when properly supplied with power, replacement may be necessary.

Common Symptoms of a Failed VANOS Solenoid

A worn or failed VANOS solenoid can cause:

• Check Engine Light — VANOS or camshaft timing-related diagnostic trouble codes may be stored.
• Loss of Low-End Torque — Incorrect camshaft timing can make the engine feel noticeably weaker at lower RPM.
• Poor Acceleration — The engine may feel sluggish or less responsive through portions of the rev range.
• Hesitation — Improper VANOS operation can cause hesitation during acceleration.
• Rough or Unstable Idle — Incorrect camshaft positioning can contribute to inconsistent engine operation.
• Reduced Engine Performance — Without proper VANOS operation, the engine cannot optimize camshaft timing for different operating conditions.

Keep in mind that VANOS fault codes can also be caused by worn internal seals, mechanical VANOS problems, wiring issues, or insufficient oil pressure. Proper diagnosis is recommended before replacing components.

Perfect for a Single VANOS Rebuild

If you're already rebuilding your BMW's Single VANOS unit, it's a good time to inspect and test the solenoid.

The solenoid can last for many years, but these vehicles are now decades old. A failed electrical coil or sticking internal valve can prevent an otherwise properly rebuilt VANOS unit from operating correctly.

A new sealing O-ring is included, allowing the solenoid to be properly resealed when installed into the VANOS housing.

Fitment Guide

Fits applicable BMW models equipped with early Single VANOS engine systems.

*Fitment can vary by production date and VANOS configuration. Early non-VANOS M50 engines do not use a VANOS solenoid, and later M52TU-equipped vehicles use a different Dual VANOS system.

Important Fitment Note

This solenoid is intended for the applicable Single VANOS system used on engines such as:

• M50TU
• M52
• S50B30US
• S52B32

BMW transitioned several models between non-VANOS, Single VANOS, and Dual VANOS engines during the 1990s. Because model years can overlap, verify the BMW part number, engine code, and VANOS configuration before ordering.

Important 530i Note

Some catalog data lists 1994–1995 530i applications for this part number. However, the E34 530i uses the M60 V8, so it should not be treated as a standard M50/M52-style Single VANOS application solely from that generic fitment listing. Verify the original part number before listing or selling this solenoid for that application.

Restore Proper VANOS Control

The seals and mechanical components inside the VANOS unit are only part of the system. The solenoid is what allows the engine management system to actually command the VANOS mechanism.

If your original solenoid is no longer actuating properly, replacing it can restore the oil control necessary for proper variable camshaft timing.

With a new sealing O-ring included, this replacement is ready to install as part of your Single VANOS repair or rebuild.
