Part Number: FMDV41. Citroen/Peugeot/Vauxhall/Opel 1.2T Atmospheric Dump Valve


FMDV41 is our blow off valve solution for the PSA 1.2 PureTech engine, which is found in most Peugeots and Citroën models from 2017 till present (fitting engine code EB2ADT). This valve has been expertly manufactured and designed in the UK, meaning we can provide the industry leading valve for your vehicle. Specifically designed for the PSA 1.2 pure tech engine, this is a fully atmospheric (blow off) valve, so you can enjoy that fantastic “pshh” sound! 




This valve is a fully engineered solution offering significantly improved reliability; this valve is piston based with no diaphragm to fail, and of all aluminium construction. It replaces the original unit with a pressure/vacuum operated piston valve that retains the desirable OEM ECU control over valve actuation. Furthermore, heavier springs are available and are easy to swap in to suit your tuning needs if you add more power to your vehicle.
