my 2004 voyager since ive had it has always had the brake light on and abs light i don't know what to do I had someone come round o scan it and no codes were found and mot is next week so im now panicking

 

Most toy boy scanners wont hack it. You need it scanned by someone with a decent quality scanner. The brake light on its own could be anything from just a brake fluid topup to something serious but combined with an ABS light suggests it will be an ABS wheel sensor on one of your four wheels.

 

ive noticed one the front wheel abs sensors on both sides the bolt holding sensor to bud have been snapped off in the hub but I cant really see or tell if the sensor head is damaged

 

Unless its totally mullied you won't see anything on the head itself. The sensors need a very precise distance to even work at all, get it reattached before your test my friend.

 

For quick fix replace both front ABS sensors. Clean/scrap off phonic/castle rings on drive shafts while lying down there. Hopefully a part of the bolt will be visible and removable with a mole wrench. You should only need one cup of tea and two biscuits for process.
