Hello, 4 months ago I bought an Alfa 156 2.0 TS built in 2001. Today I was in the workshop because in the hot weather I noticed that the air conditioning system was not really cool. (What I could not control during the test drive in winter at minus 10 degrees) The master said it was probably a hole in the system and there the cooling liquid went out. He also said that the Komnpressor did not run at all, according to his statement normal, if no coolant dri n is. ?!? What does the cooling liquid cost? and what does the repair cost about? Bez actually has to be carried by the workshop if it has been like this since the beginning?
