I've just replaced mine via Halfords. Their online listings were confusing in that it wasn't clear which one I needed so I rang my local store. They quickly said it was a Bosch A300h, as mentioned above by Mark. I ordered it and it arrived next day. The cost was £18.88 including £3 for fitting which took all of 30 seconds!
