Hello, owner of a 2011 335i xdrive. I need to perform the following adaption procedure: "Disconnect tank ventilation valve (purge valve) electrical connector and allow the engine to idle for 15 minutes. This procedure will allow the DME to readapt." The Bentley manual wasn't much help and I can't find what I need on Google... so I've turned here for any inside knowledge... Where is the ventilation valve electrical connector? It would seem that in order to access the valve you'd have to remove parts that the car needs to run... very confused and do not want to go to the dealer for something that I should be able to do myself. Thanks in advance for any guidance.
