I do not know if it changed with the 2.2 but the 2.4 has intermittent wipers, it is just not adjustable, I changed the relay for the type 99 one that allows you to program the interval. I find it really useful and use it all the time. There is a post on defender2 about adding the old relay to the rear window wiper to make that intermittent, but then I do not think the 2.2 has one anyway :D
