It is located on the intake side of the engine by the flywheel, One bolt holds it in. 8 or 10 mm.
This can be tested with an ohm meter. readings should be between 500 to 700 ohms. Anything out of this range replace it

    it should be the 10mm, you may have to use a wrench because of space and angle

Hi there?
The crankshaft sensor is located near the botom of the oil deep stick, next to the gearbox housing.
I think you may need to use special VW torx. good luck.......

Is there any special tricks to replacing Front & Rear brakes on 2003 VW Jetta TDI? Tools req'd?

The rear brakes require a specail tool, as they screw in. The tool can be bought at any auto parts store. It looks like a box with little tips on it. The front is like any other car and with a C clamp can be compressed.

Got audi a4 1996 diesel need to change cambelt but

A diesel uses a different procedure. You'll need a tool to hold the camshaft pulley parallel to the top of the cylinder head. The timing mark to set TDC for piston #1 is located on top of bell housing. The pointer must be aligned on the diamond cut on the flywheel. A VW/Audi setting bar tool #2065A is needed to lock the camshaft in position. Lock the injection pumpin position using the special lock pin (VW/Audi special tool no. 2064). Caution: If the drive belt is broken or has jumped time, do not attempt to lock the sprocket at this time!!! You will also need VW/Audi special tool no. VW210 to measure belt tension between camshaft sproket and injection pump sprocket. So good luck.

Change a crankshaft position sensor on a 2000 eclipse

Is this a V6 or 4cyl???>>>(V6) This requires removing the Harmonic balancer (crankshaft pulley). Remove (R) front wheel, remove engine splash Guard, Remove crank pulley, remove lower timing belt cover. The Crank sensor is located behind the crank shaft pulley!! I highly recommend having this done by a certified tech, requires special tools. Hopefully this helps!!
