My ABS light came on. I took the car to a very decent VW/Audi shop. I was told that the rear left ABS sensor need to be replaced. Wanted to save a few bucks. I brought the car back and ordered the sensor. Yestoday, the sensor arrived. I measured the resistance between the two wires for both the new and the old sensors. They are the same ~ 1800 Ohm.

I remamber having read from the forum that a failed sensor should have very different resistance between the two wires. Now, I am in doudt if the old sensor has really failed, and I did not rush to install the new one. But I don't find any other reason to not believe the very reputated shop. Is it possible that a failed ABS sensor has the same resistance as a good one?

I checked part numbers of the new and the old ones. They are the same.

Thanks

do you have an abs light? if so it might be the abs module that is broken

If I understand correctly, rear side is the driver side. If the module is broken. I think I should not be directed to a particular sensor. I have erased the code several times and the same code always come again in within one minute of driving (ABS light on).

But it was the front right sensor. I took off the wheel and found that the sensor wire was torn. I reconnected and fixed the wire and the ABS light went off and the ABS worked again.
