Forge Motorsport Diverter/Recirculation/Dump Valve (BOV/DV) Upgrade Kit for BMW 2 Series M235i (F22) N55 3.0 Turbo – Electronic Bypass/Charge Air Relief Valve, Plug-and-Play, Billet Aluminium, Serviceable Piston, Black, Boost Leak Fix

Performance Turbo Recirculation Upgrade for BMW M235i F22 N55

Transform the way your N55-powered BMW M235i responds on throttle with this direct-fit turbo recirc upgrade engineered by Forge. Precision CNC machined from billet aluminium with a piston design that does not rely on a diaphragm, it delivers rock-solid boost control, sharper pick-up and long-term reliability on both standard and tuned cars. A true bolt-on solution that uses the factory electrical signal for seamless ECU control, finished in stealth black for an OEM-plus look.

Why it belongs on your M235i

• Billet alloy construction that resists heat soak and warping under sustained charge pressure
• Piston-driven operation for consistent sealing and dependable boost retention
• Rebuildable and serviceable design that can be re-sprung to suit higher pressure targets
• Direct-fit loom connection to the original harness for effortless installation and factory-style actuation
• Ideal for stock calibrations and remapped setups running increased target boost
• Stealth black finish for a factory-style appearance in the engine bay

Fix the weak point, protect the turbo

The OE plastic electronically controlled valve on the F22 M235i can fatigue with age and heat, causing intermittent leaks, loss of charge pressure and even fault lights. In severe cases it can crumble on removal. This Forge unit replaces that known weak link with a robust aluminium body and piston that keeps your boost where it belongs, helping to prevent turbo overspeed, surge and performance fade.

Tuning ready confidence

• Designed for the N55 single-turbo 3.0 straight-six
• Holds stable boost on spirited road driving and track days
• Supports Stage 1 and Stage 2 remaps that demand stronger sealing
• Subtle turbo sound with improved response between shifts

Proven by us, loved by customers
