Hello,
I'm kind of hoping that somebody with VW experience can help me out with a crankshaft sensor and MRE ring. A long story short;
Our boss diagnosed the crank sensor faulty because the Passat would not start once the engine warmed up. The crank sensor on this model is not easy to access and requires a long Allen key to reach it after the oil filter housing has been removed. I asked the boss, when the engine was cranking was the rev counter needle moving at all, he said yes, so I said forget the crank sensor and move on...
Some weeks later the boss says to me, change the crank sensor it is faulty according to his scanner (Bosch KTS) latest platform. I have no problem with Bosch, just the man operating it!
Anyway after removing the oil filter housing I had not got my long reach Allen keys at work, so I said wait until I return to work Thursday (two days later) and I'll bring the keys and remove the sensor. The boss did not wait and got one of the other lads to try and remove it, and in doing so made a hash of the Allen key head. After numerous attempts at trying to remove it Thursday I gave up, the head of the bolt was too far gone. The car got left. Three months have now last and because we were quite at work the boss asked me to remove the transmission and change the sensor. I advised him that while it is now such an involved job, maybe we should also change the MRE reluctor ring while we have the car dismantled. VW charge around £100 for a crank seal kit, however the boss bought another brand through the after market for around £50. When I opened the box and read the instructions, because they instructions are multi-language I didn't properly understand what the instructions were saying. I saw the illustration that told me to position the MRE ring arrow at about 11.00 O clock position, but the instructions did not say arrow, they just showed like a pointer, which was very confusing because the MRE ring has different marks on it and an arrow. I can see that at 180 degrees apart the MRE ring has missing magnets to advise of a crank position, which I assume is to represent about 90 degrees before TDC, but it is an assumption.
Now while I have no problem with buying the proper technical information from VW online, my boss won't pay for anything and I'm damn sure I'm not paying for it out my very poor minimum wage salary from him. May I ask please, would anybody be willing to share some data or knowledge about how the MRE rings are correctly positioned when fitted, and what actually keeps the ring in its fitted position when the crank turns as it appears only to be a friction fit around the crank boss that locates the flywheel. Unless I'm seriously missing something here, I've no idea how this MRE ring stays in its fitted position?
Thanks for reading.
