Hi doe s anyone know where the camshaft sensor is on bmw 1 series f20 n47 2013?

Hi John

Welcome to the Forum

As far as I recall the sensor is on the engine cover over the front of the Inlet Camshaft

Here is an excerpt from the Engine repair manual

9.2.2. Camshaft sensor The N47TU camshaft sensor operates according to the Hall principle as with all BMW engines. The camshaft sensor is installed on the cylinder head cover above the intake camshaft. A camshaft sensor trigger wheel is mounted on the intake camshaft for this purpose. The Digital Diesel Electronics uses the camshaft sensor to detect whether the 1st cylinder is in the compression phase or the exhaust phase. This assignment cannot be made from the crankshaft position. Assignment is necessary so that fuel injection can be regulated accordingly. The DDE supplies the sensor with 5V and ground. The sensor supplies a digital signal via the signal line to the DDE. A special pattern allows emergency operation if the crankshaft sensor fails. The resolution of the camshaft sensor signal is, however, too inaccurate to replace the crankshaft sensor during normal operation.

Hope this helps

Dave
