Ok cheers ! Yeah, don't have one of those....was trying to remember what was said. I remember them saying as it is magnetiszed , a signal can be read with the wheel stationary. Like i said at before , having replaced the sensor that was possibly damaged and putting back the old CV joint it is most likely the magnetic wheel that i damaged while scraping away all the rust etc - i don't think i could have damaged the cable in the bonnet passed where the new sensor plugs in. Both sensors giving the same error code, i don't even think the bent sensor was broken. Fingers crossed...
