This is the GAS Fuel Injection forum. (Diesel remains in Fuel & Ignition Forum.) We acknowledge VW's grouping system with Electonics leaves something to be desired. The Fuel Injection system covers the fuel & air feed of all non-carburated vehicles. The "Engine Mgmt. Electronics" part refers only to the FI controling features -- coil, plugs, & ignition harnesses will be found in the Fuel & Ignition forum, as will all questions related to fuel delivery UP TO entering the Fuel Injection system. This forum covers all input sensors and controllers to the Fuel Injection system and the running problems associated with them. Please pre-diagnose your symptoms sufficient to select the proper topic to add to, using the "Post Reply" feature.
