Thank you for expanding my vocabulary.
I had no intention of offending you by my suggestion of a poll, or indeed by anything else I said, I merely thought that getting some numbers would be interesting. My primary objective is also to get MG to resolve these and other issues, under warranty where appropriate. I would have thought we were on exactly the same page there. But hey ho.
I'm still unsure about whether I should be concerned about the level of noise that I'm hearing from the aircon in my car. I would indeed be interested to know the split in the forum between those who think the sound they hear is normal and those who think it is abnormal, and if indeed there are cars which make no sound at all (either before or after regassing).
