Anti-slip regulator light goes on

after my mechanic replace the right axle assembly, my anti-slip regulator light kept flashing on. took it back & he replace the sensor. couple hundred bucks & it still goes on intermittently. he hasn’t a clue why. why?

I’m guessing this is a newer VW; a Passat maybe?

You’ll need to go to a mechanic that has either a VAS 5051 or VCDS scan tool. Someone specializing in European cars or VW/Audi/Porsche would be likely to have one. There’s no way to diagnose a problem like this over the internet. Good luck.
