I'd say the leak is rather slow. Actually, there has been no leak at all for a couple of days, and there is still some fluid left.
I just put 2 litres of fluid in and activated the washer. Both windshield and front light washers worked properly, but right after that the leak started. It was dropping behind right front wheel. However, I couldn't see the origin of the leak.
The washer reservoir is on the right side. I'd say it is in front of the rigth front wheel, at least the top of the reservoir is there. It is difficult to say exactly because I can't see the whole reservoir.
