Well guys, it is difficult to explain everything for me in english but I'll try and hope that you can help me.
It's spring already and outside temp. grows up
and I want my car's conditioner works good.
But I have some problem with it.
When I push AC button on klima
compressor clutch is starting work but no cold is going... 
only after 10-15 min when engine rpm speed goes to 2500-3000 system starting work.
Today I refilled all system with new coolant was added 440 gram as on green sticker indicated.
But it works as before compressor clutch twists but no cold... 
Here is some photos Муфта компрессора кондера включается а сама система не холодит? - BMW Club
of computer diagnostic showed first photo means before cold goes and the second one when system works great I mean cold is going.
I asked on Russia's bmw forum but nobody knows.
They advised to change coolant and I did it today unfortunately it didn't help.
Please advise what should it be?
