LeeB91 0 Report post Posted October 16, 2023 Hi my e90 BMW threw a fault code P0444 - This is the Evaporative Emission Control System Purge Control Valve Circuit Open code. The car seems to run an drive fine. How essential is it that this is fixed immediately? I understand that the Evap Cannister purge valve needs replacing ?

No check engine light any more - Yay! **Edit** - I spoke too soon, the light is back on now. Edited October 19, 2023 by LeeB91 Quote Share this post Link to post Share on other sites
