Hi there,
I had an issue with one of the rear speed sensors 2 years ago - I replaced the bearing (rusty and broken speed sensor ring) and everything was fine. But now I have another somehow similar problem - on VCDS I see both rear speed sensors show 0 speed plus many warnings about tire pressure monitor, ABS (scan follows). I replaced the opposite rear bearing and both rear speed sensors. I cleared the errors but no improvement - still 0 speed from both sensors and all the warnings come back immediately after switching the car on. Thank you in advance. Btw. - the radio is replaced so that's why these bus/CD/navigation errors.

Have you checked the wiring and connectors to the rear speed sensors - especially any common points?

How can I do this ?. Visually connectors are ok.

Its a bit odd that both rear sensors are faulty ; check to see if you have power and ground at each sensor plug. Also, economy type sensors can fail prematurely.
Genuine or OEM VW / Audi sensors are recommended.

This video should give you some insights:

Passat B7 rear ABS sensors are known to fail. What brand sensors did you use?

Original sensors I did not change. But now, I replaced (maybe not necessary, I'm not sure whether they are the problem) with Ridex.

still 0 speed from both sensors and all the warnings come back immediately after switching the car on.
As in before the car has moved -Just at Ignition on ?? If so that will not be a Wheel Bearing or Phaser - Wheel needs to turn before that can be detected.

You will need a Wiring Diagram and test those back to the ABS Module - What you need is a scope to get any level of certainty in your testing !!

Thank you all who replied !
So, paradoxically I had TWO faulty speed sensors (two rear ones) !
Don't waist your time with non-original electronic parts. FYI - I measured resistance if someone is interested. I have two different values measuring in opposite directions:

RightRightLeftLeft
Faulty (old ones) - original VWopen7.6 MΩopen7.6 MΩ
New - original VW90 kΩ13 kΩ (rising)90 kΩ13 kΩ (rising)
New (didn't work) - Ridex13 MΩ4 MΩ13 MΩ4 MΩ

So I just replaced Ridex with VW, erase error codes and everything works now.

I mean if you install shit parts you get shit results especially in any German vehicle.

Not exactly, I did it for many mechanical parts, disk brakes, pads, bearings, some suspension stuff - some are better than original ! Obviously for electronics is risky.

No such thing as better than original.

There have been some exceptions, particularly with mechanical parts, but they are pretty rare.
