Detailed Description

Standard Ignition VVT508 is a replacement exhaust VVT sprocket for BMW engines that use camshaft phaser control. It is engineered with a metal gear, 44 teeth, and four timing marks to support correct cam timing during service. This part number is used across multiple BMW exhaust positions, including 2000-2003 BMW 540i and X5, 2004-2010 BMW X5, and 2006-2010 BMW 550i, 650Ci, 650i, 750i, and 750Li applications. Standard Ignition VVT508 also fits 2014-2016 BMW 750i, 750Li, and 550i exhaust applications listed for cylinders 1, 2, 3, and 4.

What It Helps Address

• Cam timing faults related to a worn or sticking exhaust phaser
• Check engine lights tied to variable valve timing performance
• Rough idle or inconsistent engine response from timing control issues
• Noise from a damaged or worn VVT sprocket assembly
• Timing alignment problems during exhaust cam service on BMW engines

Installation Notes and Tips

Verify engine code, exhaust position, and cylinder application before installation. Match the 44-tooth layout and timing marks to the original component, and inspect related timing components, guides, and seals during service. Because hardware is not included, reuse or source any required fasteners separately as specified by the vehicle service procedure.

Quality Assurance

Standard Ignition supplies this VVT sprocket as a direct replacement-style valvetrain component for BMW exhaust cam applications. Confirm fitment against the vehicle’s year, model, and position before installation. Part number VVT508 is listed with interchange references 35-1309 and 11367506776.
