Forge Motorsport Recirculating BOV/Diverter Valve (DV) Kit for BMW 2 Series M235i F22 N55 3.0L Turbo - Plug-and-Play Electronic Bypass/Dump Valve Replacement, Quiet Closed-Loop Turbo Pressure Relief, All-Aluminium Piston

BMW M235i F22 N55 turbo pressure relief upgrade by Forge Motorsport: quiet, direct-fit, metal piston design

Replace the failure-prone factory unit on your BMW 2 Series M235i with this Forge Motorsport closed-loop boost release valve kit. Engineered for the 3.0 N55 single turbo, it is a direct-fit electronic return-to-intake solution that keeps lift-off operation smooth and silent while holding boost far more reliably than the stock plastic part.

If you are searching for an M235i turbo blow-off replacement that maintains OEM manners, an N55 boost control return valve that is plug-in compatible, or a sturdier charge-air relief valve for tuned cars, this Forge kit is the premium answer. We have installed and run this ourselves, and our customers love the refined driveability and leak-free performance.

What you get

• Direct-fit electronic turbo pressure relief valve for BMW M235i F22 N55 3.0 petrol turbo
• CNC-machined aluminium body with a serviceable piston, no rubber diaphragm to perish
• Included plug-in electrical connector for genuine bolt-on installation
• Quiet closed-loop return operation for factory-like behaviour
• Spring can be changed to suit increased boost when mapped
• Ideal on standard cars and remapped cars seeking dependable boost control
• Finish: black

Why upgrade on the M235i

The original plastic valve on the N55 is known to weaken with age and heat. That can cause boost leaks, intermittent power loss, and fault codes that are hard to trace. In severe cases the OE unit can break during removal. Forge’s all-metal, piston-operated construction is built to last, helping to safeguard the turbocharger and maintain consistent boost pressure on spirited drives and trackdays alike.

Made for tuning, perfect for daily use

Whether your M235i is stock or running a Stage 1 or Stage 2 calibration, this ECU-controlled return valve copes with raised boost without the whoosh of a vent-to-atmosphere setup. Expect crisp throttle lift-off, stable idle, and strong boost retention pull after pull.

Fitment

Compatible with BMW M235i F22 using the N55 3.0 single turbo with an electronically controlled valve location. Designed as a like-for-like electronic unit with the correct connector and mounting.
