Now no fault come up.

Do you have to replace the disc? Can you replace the abs ring without replacing the brake disc?

Depending on score made on abs sensor ring, for my I had to replace disc because ring on disc scored best to change both of them same time

[@johnbateman2462]

You can just replace the abs ring

[@kerbsideauto4940]

You can replace abs or complete disc come with abs Ring

What should the gap be between the ring and sensor? I replaced the sensor for C1335 error and now I'm getting C1336 DTC.
Thanks
