And if that doesn't work, then Modulemaster.com is your friend.

Hooking to a VAG should indeed tell you which corner is bad. It will be obvious which sensor has the wrong/deviated return values.

 

Any idea what blocks in vag to be looking at for that? I was never able to find them when I was trying to diagnose mine.

 

Did you try block 03?

 

If you check measuring blocks on VAG it will show individual wheel speeds. The one that is different from the rest is the culprit. I would think that if you repeatedly press the brakes when coming to a stop, the ABS light should eventually come on and throw a code, it doesnt know theres a problem immedietly until it sees the same wheel sensor constantly showing a different wheel speed.

When i did my front end i didnt push the wheel speed sensor in far enough so i did whats above to diagnose which side it was.
