Crankshaft Sensor

I have the following code:

Code:

2A94 
2A94 crankshaft sensor signal

So I believe I need a new crankshaft sensor. However, when I look around for DIY, there are multiple places people point to where this sensor is located. I located it here, and just want to make sure it is correct?

the crankshaft sensor is not anywhere at the front of the engine - it's on the side of the block, under the intake manifold, on the driver's side. those are cam sensors and vanos solenoids.

I believe I mistook CAMSHAFT sensor to CRANKSHAFT sensor. Thanks for the clarification.

On the N54 turbo engine, the crankshaft sensor is located on the driver side of the engine block near the rear of the engine under the intake manifold and tucked in under the starter. I know because I just replaced it. I suspect the non-turbo engine would be located similarly.

yeah, it's pretty much identical.

Here is a DIY writeup for the crankshaft sensor on the N54 with photos:
