Changing the valve body is simple if you are meticulous about detail and cleanliness although its a very messy job in the car since it holds a lot of oil which will drop on you I would argue though that if its shifting ok then changing it is a waste of money. The best preventive maintenance on it is to change the bearing, but that's inside the box behind the oil pump so is a considerably bigger job. Still, its pretty obvious when that bearing has failed (clutches slipping) and if you get to it immediately it won't do any lasting damage.
MikkiJayne - I know you posted this in relation to a D2 and a valve body but I'm wondering if this sort of thing is happening on my D3 ???

I've had the error on multiple gear ratios which would indicate something related - Curiously whilst driving this morning, I put it in 4th for a bit and i got fluctuating revs and even lurchy type behavior whilst in one gear!
