My car is an 05 plate and was recalled for the washer (and had it done - that's my hand holding the washer a few pages back in this thread!). It has affected 05 onwards. I know of some 07 plates that have been recalled.

I think they have been told to update the software first (it'll save them money on replacing a new unit remember!) but it sounds like it'll happen again so the unit will be replaced.
