Golf 7.5. Left rear level/height sensor/sender replacement (G76). 5Q0907503 (5Q0512521E).
5Q0907503 is the level sensor - used for the front or rear axles -.
5Q0512521E is the parts assembly for a rear torsion axle.
Since I had the happy idea
of cleaning the rear axle with high-pressure water jet - when I installed the new blue rear brake calipers - ...
... I have been randomly experiencing a malfunction of the left rear level sensor, mechanical failure according to diagnosis.

By doing a new ignition cycle, the fault disappears and everything works fine again for a while until the Light Assist and AFS system (cornering lights) malfunction warnings are displayed on the AID and info system again.
I have replaced the sensor for a new one and everything works correctly now, the fault has not reappeared.
Stainless steel bolts, same as those factory installed on the sensor.
I also installed new M5 stainless steel rivet nuts of better quality than the original ones.
A meaningless look at the other side...
everything seems fine after 1500Km on our magic carpet.
This is the rear level sensor that was causing the problem:
- Dirty.
- Clean (for inspection).
It's the one I installed when installing the 8IU Matrix LED headlights.

Inspection:
The sensor shaft/rotor has no axial play, but it has a small/micrometric radial play/clearance, which seems to be enough for its malfunction.
