Well, I did remove both front sensors today. I could indeed notice quite a bit of iron "dust" gathered around the tip of the sensor.

I cleared that out on both sides.

Then I looked down the hole with a flahlight. I could see the toothed wheel. It is rusted quite a bit, but I can clearly see that all teeth are still there.

So I used a steel pick (kind of screw driver but with a pointed end), and scraped every single "valley" between the teeth.

And, unfortunately, it didn't do a thing. Same symptoms.

I need to test everything before I start throwing expensive parts in there.

To be continued!

Bye,
