@ tony buon- well worth the money mate saves the cost of jaguar doing it!! I just recently had to take mine to jag for a scan before I decided to by one as my abs light came on. They said it was my near side rear abs sensor was broken and the off side was on the way out. I took it to my mechanic and he replaced both the sensors. The light remained on. Reset the light with the scanner and as I drove down the road it came back on. I drove straight to jag and told them I replaced everything on the report they had given me and the light remained. They plugged it back in for free this time and now tell me the fault is being caused by the original near side rear sensor but this time the abs module or faulty wiring. I just got back from holiday today and have left my car with my mechanic. I'm going to collect it in the morning hoping the issue is now resolved. But it goes to show you pay all that money for jaguar to full scan to find the issue and they can still mess it up. It's driving me mad at the moment. @ Steve 341 after still currently tryi g to get to the bottom of the same issue it could be a sensor, one of the reluctor rings ( the sensor reads the grooves off this ring. Not an expensive part ) or faulty wiring or module.
