Wheel bearing Change brings ABS light on

[Simon Bathard]

C219 / 2007 320CLS front hub grease seal is the ABS sensor ring. It must be re-fitted to give the correct air gap to the ABS sensor. Otherwise, the ABS light comes on along with EPS and cruise control switched off. I changed the ABS sensor and the brake switch so I hope this helps others to avoid making the same mistake as I did, by tapping the grease seal just too far into the hub. My first Merc and it's fabulous..now.
