when replacing a rear wheel bearing, i appear to have knackered that hub's abs sensor, not too much of a problem as i plan to remove the system, but before i get the time to remove it i have got it booked in for mapping, the fact that the abs light is on on the dash is rubbish, but will this effect the cars performance ecu/timing wise? I know it effects the braking!t

 

No effect on tuning. ABS light was on for ages on mine before i fitted new sensors.

 

nice one mate cheers.
