Diverter Valves (DV) for Mercedes Turbo Engines

A diverter valve is the factory-style turbo pressure relief valve used on many modern Mercedes turbo platforms. Instead of venting boost to atmosphere, a DV recirculates air back into the intake for smoother drivability, faster boost recovery, and consistent power—especially on tuned or higher-mileage vehicles.

  • Sharper throttle response
  • Faster boost recovery
  • Improved boost holding
  • Helps reduce boost leaks
  • OEM-style drivability
  • No “vent-to-atmosphere” noise

Why upgrade your diverter valve?

Factory valves often use plastic internals that can wear, leak, or fail under heat and boost. A quality DV upgrade improves sealing and response for more consistent boost pressure and repeatable performance.

Looking for a “BOV” sound?

Many shoppers search “blow-off valve,” but Mercedes turbo systems are typically optimized around recirculating diverter valves. If your goal is real performance and boost control, you’re in the right place.

Fitment tip: Always confirm your engine platform and model year before ordering. Some applications require one diverter valve, while twin-turbo platforms may require two.
