Detailed Description

The Standard Ignition VVT342 is an exhaust variable valve timing oil control valve used to regulate oil flow within the VVT system. By controlling oil pressure to the valve timing mechanism, it supports proper exhaust cam timing on select Mercedes-Benz GL550 and ML550 applications. This part cross-references 35-1234 for the same application.

Use Standard Ignition VVT342 when servicing an exhaust-side VVT oil control valve on 2008-2012 Mercedes-Benz GL550 or 2008-2011 Mercedes-Benz ML550 models. The compact metal-bodied design and single male electrical connection make it a practical replacement for vehicles requiring this specific valve configuration.

Common Issues This Part Addresses

• Exhaust cam timing faults related to oil control valve operation
• Rough idle caused by inconsistent variable valve timing response
• Check engine lights tied to VVT system performance
• Oil flow control problems in the exhaust timing circuit
• Driveability concerns linked to delayed valve timing adjustment

Installation Notes and Tips

Verify the exhaust position and connector style before installation. Inspect the mating surface and electrical connector for wear or contamination, and confirm the shaft diameter and overall dimensions match the original unit. Gaskets and mounting hardware are not included, so reuse or replace related sealing components as needed during service.

Quality Assurance

Standard Ignition manufactures replacement engine management components for service applications that require accurate fit and function. Part number VVT342 is built to match the listed Mercedes-Benz exhaust VVT applications and interchange references for straightforward parts lookup.
