Hi all. this is my first post. I have had similar problems. The car went in for brake disks change but the garage had difficulty getting the rear disk off. In the process they damaged the ABS sensor. I then got all the warning lights as mentioned above. A new ABS sensor didn't cure the problem but fitting a genuine Vauxhall one did clear most of the warning lights.
The problem is I still have an engine warning light that wont reset. Error Code P1349. That's a MOT failure and It wont reset although the car seems to work perfectly.
Any Ideas?
