I just realised there is no air coming out of the passenger side air vent on my 2010 A6.
I thought the air was a little bit warmer than usual so i had it regassed.
After checking more thoroughly there is no air coming from the left side air vent and the drivers side air is a little bit warmer than the centre vents which are cool.

Its not the climatronic but the standard aircon with the 4 dials.

Any ideas?
Something simple would be nice

Thanks
