Have just changed the front CV and wheel bearing britpart. Drove1/2 mile 3 lights came on. Replaced sensor with old one traction control now comes on. Should I try one more new sensor or send wheel bearing back?

I bought a 2004 TD5 about 8 months ago its the 5 seater no sunroofs to worry about. Have done an oil service and filters will complete the EGR and decat once the bits arrive. This is the second disco I have had first was the 4 lt V8 again 2004 nice motor but brakes a bit suspect with the auto...
