Access is via wheel arch cover drivers side. Turn steering to right. There is three plastic pop out fittings, lever out centre piece they then come out. One small screw and one larger screw allows you to pull down wheel arch cover. Motor is attached to bottom of windscreen water bottle, same motor operates front and back washers with two electrical connections and two rubber tubes.
There is a rubber washer between the motor and the water bottle.
I had my 207 checked fault was not in the motor but in connection from sender unit underneath bonnet.
