Walker 590-1161 Engine Variable Valve Timing (VVT) Solenoid

OE Replacement VVT Solenoid

Walker 590-1161 is an engine variable valve timing solenoid built to restore camshaft timing control on select BMW applications. It regulates pressurized oil flow to the cam phaser or VVT sprocket, helping the engine adjust valve timing as driving conditions change. This part is a direct-fit OE replacement for BMW 323i, 325i, 328i, M3, and related models.

• OE-style replacement for variable valve timing control
• Heat-resistant plastic housing for engine-bay durability
• Precision internal valve design for oil flow regulation
• Oil-sealed connector for improved electrical connection integrity
• Square female connector with 2 blade terminals
• Seal included for a factory-style service replacement
• Walker 590-1161 for BMW VVT service and timing repair

What It Helps Resolve

• Cam timing fault codes such as P0010-P0014 and P0020-P0024
• Rough idle caused by VVT control issues
• Hesitation during acceleration
• Reduced engine power from sticking or failed solenoid operation
• Oil-flow control problems affecting valve timing response

Installation Notes

Use the factory connector and mounting points for installation. Inspect the engine oil condition and the VVT oil passages before replacement, since sludge or contamination can affect solenoid operation. Confirm the connector shape, terminal count, and seal condition against the original part before installation. Walker 590-1161 is designed for exact OE fit on the listed BMW applications.

Quality Assurance

Walker Products engineers these VVT solenoids to meet or exceed OE specifications for electrical response, oil flow control, and pressure regulation. The design uses a heat-resistant housing, precision-machined internal valve components, and sealed electrical connections to support reliable operation in continuous engine service.
