Hi.. I dont know about a drastic change like that - the only one I know is that the updated ones have an 'X' on the end of the part no. if that helps...but basically its identical n looks at least. As for the cam sensor - thats interesting! Im always having to gve the connector on my own one a good wiggle cos its always losing its connection- putting the MIL on. So, I'll look into that - ta Mike
