Allright, I reset the codes by pressing 8 times+ the brake pedal, drove a few KM and only 35 came back. It might in the end be related to this axle seal replacement on passenger side. Will take a look at it tomorrow.

I just removed the sensor to take a look at it. The sensor itself was covered with drips of rust. Looking inside the hole, there was also a lot of rust. Could it be a cause for "foreign material on sensor"? Is this sensor supposed to be completely sealed to protect the inside? I'm not sure if I saw rust in there when I removed the sensor on the other side a few weeks ago.

After cleaning the sensor and putting it back, clearing the code, the ABS light came back within 100 meters, again with a 35 code.

I will check the sensor for continuity later tonight or tomorrow. If the sensor itself looks good and there isn't supposed to be rust there, what parts could need replacement?

Thank you!

The 35 could be due to foreign matter on the tip of the sensor or on the ring that the sensor reads. The rust visible through the hole could mean that the ring is coated.

The ring, by the way, is part of the end of the front axle.

By front axle, do you mean the end of the CV axle/driveshaft, or the hub?

Yes - The end of the CV axle/driveshaft, just before where the spline enters the hub.

The problem is finally fixed. There was so much rust on top of the sensor hole and within the hole that I'm pretty sure that the sensor shifted. It was impossible to put it back in place correctly.

I sanded all the rust on top of and in the hole, removed a few rust flakes near where the sensor tip gets, put some grease on top of the hole and on the base of the sensor to avoid water getting in and I put it back completely in. After clearing the code and driving many KMs, the light didn't come back.
