Hello everyone, I have a 2004 1.4 HDI. I noticed a slight crack in the auxiliary water tank and it's leaking. Unfortunately, I can't find a replacement anywhere. I have the four-outlet type with sensors. Those familiar with this type know that there's another line coming from the thermostat housing, and water is constantly circulating through the auxiliary water tank, which also bleeds air from the system. There are some 307 models with two inlets and no sensors. The developer says you can make this up, but I'm confused. Now, if I buy this type, use the outlet from the thermostat housing only for air removal, and then plug it with a blanking plug, will it cause a problem?
