Because we need to fill our washer tank from time to time the initial location we picked was not suitable.
We had hidden a round reservoir underneath the windscreen and plastic cover on the navoiator side of the car. We thought this was a ingenious idea but there was no room left for the filler cap.
This meant Dirk needed to make another tank starting from some home made pieces.. it seemed like arts and crafts in the kinder garten again.
The new washer tank has a content of 2 litre so we think we have enough water to drive from service to service.
