Hello, my girlfriend has a K12 65 Ps BJ 2005. The air conditioning line is leaking at the typical place. Workshop wants over 400 euros. The part alone would cost almost 300€. From parts recycler you get the line itself quite cheap. Does anyone know if it is a big drama to change the line? What do you have to bear in mind, you get good everywhere? I haven’t looked at it yet, but screw a lot on my vehicles in general. Only on a climate I have nothing yet Thank you for your help.
