StuartVR6 0 Posted January 21, 2008 Report Share Posted January 21, 2008 Hi The cam Position (Hall) Sensor is on the Right hand side of the engine as your looking at it, above the Coil Pack.

AAARRRGHHHH! anyone please tell me what to do did i replace the right part, i changed the one stuart gave me the part number for. Link to post Share on other sites
jezmoz 0 Posted January 21, 2008 Report Share Posted January 21, 2008 have you checked the battery? Link to post Share on other sites
c11rgd 0 Posted January 22, 2008 Author Report Share Posted January 22, 2008 all terminals on the battery are nice and tight, the lights all stay on! its just not starting, and then after around 15minutes it does. just the engine cuts out!!Stu i noted you call it the CAM hall sender is this not different to the Crankshaft sensor which i am looking for and is listed here!http://www.thephirm.co.uk/Pages/faq.html#mk3_mk3ok so i think ive changed the wrong one! ive changed the CAM sensor and not the CRANK!the error code i had was *** Engine Speed / Reference Sensor (G28) ***Engine speed and crankshaft position are registered by a single sensorlocated on the engine block.The sensor reads a toothed wheel mounted on the crankshaft to readengine speed.The toothed wheel has a two-tooth gap which is used as the measuringpoint for the crankshaft position.which refers tohttp://forums.vwvortex.com/zerothread?id=2934505can someone confirm the part number? is it 021 906 433 C Link to post Share on other sites
Samson 0 Posted January 22, 2008 Report Share Posted January 22, 2008 Hi c11rgd,The Crankshaft sits right at the bottom of the engine and the sensor is also right at the bottom of the engine.I had the EXACT same problem on my VR and the camshaft (different to the CRANKshaft) sensor is what was wrong with mine.The CAMshaft sensor sits on the right hand side of the head, right at the top of the engine, held in by one allen key bolt.You may have taken the coil pack off in order to take it out although some people manage without taking it off.The error message is definately reading CRANKSHAFT sensor, ive looked on ETKA but for the life of me can not find the crankshaft sensor listed or shown on diagrams, I will look when I have more time though.

Samson 0 Posted January 22, 2008 Report Share Posted January 22, 2008 by the way, you may need to clear any error codes just to give the ECU a clean bill of health otherwise it may still think the sensor is screwed. Link to post Share on other sites
adamsimmons 0 Posted January 22, 2008 Report Share Posted January 22, 2008 To make sure that the sensor has gone can you check the resistance across the sensor. The sensor should be white, and you need to measure across pin 1+2 and you should have a resistance between 480-1000 ohms with the plug disconnected, also check pins 1+3 and 2+3 there should be no continuity or open circuit between these pins. If any of these tests show any thing other than specified it will prove that the sensor is faulty. I hope this helps rectify your problem with your vr, I'm sure you will find it soon Link to post Share on other sites

c11rgd 0 Posted January 22, 2008 Author Report Share Posted January 22, 2008 at this point the images i posted regarding the diagnosis originally were wiped clean. then when the car did cut out we checked it again and it was the CRANK sensor G28 only showing, as SAMSON mentioned i need the part number for this and not the one for the CAM.

Samson 0 Posted January 23, 2008 Report Share Posted January 23, 2008 yeah they are much more expensive than the camshaft sensor but will be worth it if it sorts it. Link to post Share on other sites

c11rgd 0 Posted February 4, 2008 Author Report Share Posted February 4, 2008 not sure i think this one is called autodiagnose, a friend of mine is the specialist, there are a large variety ofmachines, even some from Snap on and Bosch any good trusted workshop should have this,For all this did sort out the Problem! the car needed a new CRANKSHAFT SENSOR< all sorted now!
