Hi, I am replacing the crank angle sensor or RPM sensor as Audi calls it. I have the sensor out and have threaded the wire up under the inlet manifold but from here I cannot see where it goes so that I can unplug it to take it fully out. Can you please let me know where the plug is located. I have wriggled the wire back and forward and just cant see where it disappears to and where it terminates. I had a good look online and cant find the info anywhere. I appreciate your help many thanks in advance. Cheers.

Hi Ken
Not sure how I can be clearer. I have the sensor itself out of the transmission casing. I have pulled it up to the top of the engine and released the attached wire as far as I can. The sensor wire seems to disappear up under the inlet manifold. I am trying to trace it back to where it is plugged into as I do not want to have to pull off the inlet manifold just to see where the wire goes so I can unplug it. I cant get the camera in to take a video as you will not see anything it is all very crowded in pipes and wiring. I have attached a couple of pictures but you cannot see anything of any use. Once I can find where it is plugged in I can unplug it and pull the sensor out and test it and if need be replace it.
Just need to know if you have access to any information that tells you the location of where the crank sensor is plugged into the wiring harness.

Cheers

It really does not show where it plugs in I have the component locations and the wiring diagrams so you can see the wire color but access is not shown. Here is the wiring and component locations though.

Check out the diagrams (below). Please let us know what happens.

Thanks Ken
The diagrams show me the wire colors and what pins they eventually terminate on the computer harness but they do not show me where the intermediate plug is located so I can unplug the crank sensor and test/replace. I will have to remove the intake manifold so I can see where the wire goes. I was just trying to avoid disturbing everything for what should be a very simple procedure. I appreciate your help as always anyway.
I always have a project of some sort going on so I am sure it will not be the last time you hear from me. The next one in line is a BMW E46 that I purchased with the engine completely pulled apart and sitting in the trunk so I will probably need a few pointers on that one as well.
Cheers

Hi Ken
Just an update in case the question is ever asked again on the crank sensor plug location. I found it mounted on a bracket along with two other plugs tucked right under the inlet manifold. It is a bugger to get to. Mine the grey plug in the middle of the other two. The only way to disconnect it without taking the inlet manifold off is unbolt the bracket from the block. There is a M13 bolt holding it on and you can get to it with a long extension bar. From there it is a bit of a juggle but it is possible to do. Getting it back in is also not a simple task but still possible with a magnet extension. Happy days all running now the crank sensor was totally stuffed no signal at all.
Cheers for your help.
