Due to engine mounting failure, AC pipes got some damage and leakage. I took car to local AC specialist, also took there a complete system from a spares car that had been without fluid for some time. Some pipes changed to good ones, otherwise ready for filing, but now it appears that both compressors have leakage, from both back and front gaskets.
I got quote EUR650 for a replacement compressor. Sounds expensive compared to U.S. prices, here examples
