IHK 11 Posted July 19, 2020 Posted July 19, 2020 Hi ive been having trouble with my 1993 Audi coupe 2.3e b4 ng engine not starting recently and i have changed many parts. Does anyone know where the mass air flow sensor is located or have a part number for it? Any opinions would be appreciated. Thanks Ian!!!
Steve Q Posted July 20, 2020 Posted July 20, 2020 If you locate your airbox and cold air fed that leads to it then it'll be between the two, on the top or front of the engine probably. Cheers Steve

Quill Posted October 15, 2020 Posted October 15, 2020 Hi, I can't say for sure whether the 2.0l engine has one. The 2.6l engine doesn't. In this case I think the air flow rate is calculated by the ECU from the signal from the pressure sensor in the inlet manifold. Regards Clive
