My initial warning came up, then went off, then came back on when I started the car again half an hour later.
My code reader couldn’t see it, but having read the posts elsewhere I decided to do the job myself as it’s really easy and is better than killing the ABS. All seems well again now.
It’s due a main dealer service in September, so let’s see if the fault is in the log.
It will be interesting to see what the mechanic says. I wonder if all knowledge will be denied of the issue with the countless others who are reporting back to this forum.
