Vag-com is a must it saved me alot of money by diagnosing the car and replacing the camshaft sensor myself... oh and of course help from the guys on the forum.

The car wont go to batch injection on the new cars.
It will affect starting etc and wont control knock that well.
If this is on a tdi replace the unit as it will give you issues big time latter.It sits behind the cam pully so you need to remove the belt etc to get to it.

If what you say is true, prusink, I've got a problem. We have a customer that came in yesterday whose car has an intermittent cam position sensor code 'open or short to ground circuit' for a BEW. The VCDS/ Engine module/ Block 4 reading for the cam position is set at +.5. However, when the code pops up, the cam position sensor defaults to 0.0.

If the cam sensor means nothing after the car starts, try unplugging the cam sensor while the car is running... car dies.

I believe the cam position sensor is CONSTANTLY reading the cam position, just like it's reading the injector balance; from idle clear through maximum rpm. If your cam sensor is giving a 'no read', I am sure you will be losing substantial fuel economy.

As for removing the sensor, first be aware that the 'no read' may have to do with a Service Bulletin that concerns the ground wire for the cam sensor. The wire may not be grounding correctly. The fix is to cut the ground wire and attach it to an access point close to the plug-in. There is a bolt that we attach the wire to that holds the water pipe across the front of the block.

If you choose to remove the sensor, you have to remove the timing belt, pulley, and some screws that hold the timing belt backing plate to the cylinder head. It's very close to remove the cam sensor, but it's doable. Make sure the sensor is bad before you bother taking it out. They don't often fail.

The other thing to check is that the 'fingers' of the cam sensor wheel are not bent. If you have erratic distances between the cam sensor and the fingers, you can get a bad read.

The wiring could be bad, the camshaft position sensor could be bad, or its plug not seated. "Implausible signal" simply means its not being read and "intermittent" means just that, its sporadic. Try unplugging the sensor connector and plugging it in again. If that does not fix it, you're next step is either to replace the camshaft position sensor (if its not too expensive and fairly easy), or check for continuity from the sensor plug to the ECU, bearing in mind that even if the wiring shows continuity, there still could be a break. Wiggle the wiring while doing the continuity check to make sure its not intermittent.

Remove timing belt cover, look slightly below and to the right of the cam pulley. Remove the one bolt fastening the sensor in place. Pop out the rubber plug in the backing plate, unclip the wire from the harness holder and disconnect the plug. Fish the sensor wire and plug thru the hole in the backing plate.

Fwiw the rubber plug can become dried out, brittle and break. Order a new one to be safe, part # is 1e0971904 .

that's what it looked to me, having an intermittent error with my camshaft sensor too. I did find out that if you clean the surface of it , the error goes away.

How dificult was it to replace the camshaft position sensor?

Took me about half hour i did it in my lunch time. It was really easy to replace, the hardest part was finding it.

Will take pics later after work and add some info

Oh well, hope it resolves my issue too! Seeing as there are fellow owners here, who has the highest mileage amongst us here? Reason I am asking is, my car is doing 183000kms and I have 2 years left to free the car, so I was wondering if its worth keeping? I love this car but DAMN if its reaching its lifespan.....
