Hello, I have here an Audi 100 C3 type 44 1.8s Limo with which unfortunately the heating cooler is defective. I had changed this already years ago to my Audi 80 1.8s and therefore knows that it was quite time consuming the complete amature board had to get out etc. But in itself you could do all this yourself. I also have a new cooler from the 80s lying. Now my question is that at the 100s also has to be out there amature board, or not because the front has the water box and I think there’s the ventilation inside if I’m not mistaken. If that’s how it would have to be easier in itself with the 100s or ? Do you also know if the cooler from the 80s fits or do I have to order another ? mfg Overroller
