[QUOTE="zidee, post: 470764, member: 20151"] I guess you symptom is something like what i describe in my reply before. Try to rev the accelerator for a while and see whether the cold air comes in. For the smell in cabin its indicate coil problem as well. Naidu should be able to tell and use his leaking tester. Another issue could indicate that the way BMW compressor being design which I read somewhere where the compressor is being design to de-compress when not being used for sometimes or when left not running is hot condition. According to them to preserve the life span of the compressor. (that is why when we rev for a while it build back the compression....I think so) But then we are not like in Europe where they do not get extreme hot weather. Perhaps it has to do with how the sensor being set based on Europe weather if UK model. Perhaps change the sensor first and filter will solve the issue instead of change the whole compressor.
