Hey could you help with a similar issue, 2010 Insignia elite, moved off one morning and straight away the ABS/ESP lights come one. The code is coming back as C0040-0F right front wheel speed sensor erratic. Without having access to live data i thought id go for cheapest option and changed the abs sensor but fault reoccurs. What is the chance of this being a faulty wheel bearing? this car has no reluctor ring. Ps can you confirm, when it says right front, is that right as you sit in the drivers seat or right as you look from the front of the car. Thankyou
