Broke the rear right sensor when trying to remove.
While waiting for a replacement sensor (that hopefully fits), can I get an alignment done and drive the car?

Or, will I have to take the rear hub apart again and need alignment to install the new sensor (currently, the 'copper sleeve' is still in the hole; not sure if a new/used sensor will come with it).

What is the car doing (aside from ABS and Brake dash lights on) with the sensor missing?

 

yes you can drive it but the brakes may be a little weird. no mechanical or electrical issue will pop if you drive it.

When I had something similar happen, I decided to pull the ABS fuse. The reason being that when I braked, the car would brake funny and sort of steer the car when I braked. After I braked enough it would figure out there was a problem and turn on the ABS light, but it took a few times. If your ABS light is on all the time than I wouldnt worry about it, otherwise I would suggest pulling you fuse in the meantime (which will cause a flashing brake light combo btw).

 

You can have it checked with a Vagcom or the dealer can use their OBD2 tool to check to see which sensor is not working.

 

I replaced the broken sensor (right left), this one is working.
But (likely from wiggeling/turning to get them out), the front left is causing the fault. I tried to push it further in (at one point could hear the sensor touching the teeth, so move out a bit).

Is there an electrical check that I can do to see if I messed up the sensor/wires itself, or if it is a matter of positioning (gap)?

Also: still have not find good instructions to remove sensor (last one needed drilling out). Is the sheet metal 'cage' supposed to stay in the hub and the sensor pulls out? Or both?

What is the best method? Unplug sensor cable, then turn+pull? Leverage with tire iron/screw driver?

if you have vag com, you can check the impulses on each sensor while driving. you can easily tell if one of them is showing numbers way off than the others.

as far as removing them goes, there's not much you can do. it's 2 different metals in contact and over time, they eventually fuse together

 

Make sure to let me know if you ever get a good tip.
I destroyed one totally (ripped it off, had to drill out) and one partially (now error code on this one) when trying to turn the sensor to get it out (turns out its just the top with the cables/wires turning, the rest is stock solid).

I had the hub out, so drilling wasn't so much of a problem (drilled a bit smaller certainly, and had almost the entire sheetmetal cage still intakt).

But with the hub on, I wouldn't dare the drilling.

 

After replacing the right rear (working), we found that the left front is not working (we likely destroyed it when trying to remove it, possibly by turning the sensor CAP (we thought the entire sensor maybe turning) several times, ripping the solid internal wires?).

Need good advise how to go about replacing this one now. Preferably without taking the hub off.

If the hub has to come off: is alignment needed again?
