Thanks for the response. I completed the job today. Removing the wheel hub bolt took a lot of effort. I had to use a 35mm diameter breaker bar with a 1” drive M18 socket. To add to that, I used a piece of scaffold tube as an extension to the breaker bar. Removal of the actual wheel bearing was easy enough, doing so allowed access to the broken speed sensor which was tapped out using a Philips screwdriver. The old bearing was badly corroded around the reluctor ring which is probably why the signal failed. Anyway, I found the torque setting from. VW forum.. it’s the same as a golf. All done now and warnings disappeared after a few rotations of the wheel (thought I might have had to erase the codes). Thanks again. 👍
