Belt disc makes noises PFFT PFFT

Hello, for a good 4 months a Pfft Pfft was heard mainly at the cold start on the belt side of my V50 1.6D. Well can be Lima or compressor or anything else. Now three weeks ago a high constant sound at stand gas joined, which is not to be heard when driving. Since today I know what that was. Lima defective everything to death, ADAC sends greetings (secure checked). When driving came first all error messages, then total failure. Now I have the belt down and the mo now only the crankshaft turns, but unfortunately still with Pfft Pfft. If I spray WD40 on it is short rest, but comes again at the next start. Now the question of all questions (remote diagnosis) Does it bring what to replace the belt disc (vibration damper)? How can I get the down, when the screw turns the crankshaft turns with? and then I need a puller? Or do I get it with 2 screw pulls as lifting iron? nk for your help Frank
