Recently I got a service engine soon light on my 2009 BMW 335i, after running the coded I found a 2B3D DMTL Pump (Diagnostic Module Tank Leakage) code. This is part of the Evap system which catches gas fumes and recycles them back into the gas tank. Unfortunately BMW uses a plastic pump that sits very close to the drivers side exhaust which produces a lot of heat which I believe contributes to these parts failing. I ordered an OEM Bosch replacement part. This was a much easier DIY than I was expecting and took me all of 30 minutes to complete.
