This blow off valve, or dump valve is for the BMW 235 3.0 Petrol Turbo engine, as found in the F22 chassis model that has a single electronically controlled bypass valve. This product is recommended for both unmodified vehicles and any vehicle where the boost pressure has been increased by an ECU software upgrade, as a replacement to the OEM bypass valve. Unfortunately the standard valve fails when the plastic deteriorates with age normally resulting in a check engine light. Unfortunately the valve may still partially function, so you may not be aware that you are losing power due to this. This particular failure can also result in the valve falling apart upon removal from the turbo, and in extreme cases, bits of plastic entering the turbo, resulting in serious damage.

Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based, with no diaphragm to fail, and with a body of all aluminium construction. It’s also fully serviceable and the spring strength can be changed to suit increased boost levels. Most importantly it still also retains the desirable OEM ECU control over valve actuation, with the inclusion of an electrical harness that plugs straight into the BMW wiring. It’s literally plug and play.
