Hi folks, I'm looking at buying an A6 and have been looking for the right spec/price combination for a while. I came across one yesterday, a 3.0 TDI S Line spec A6 Quattro saloon, 55 plate. I noticed that the climate control which I've seen in most A6' I've seen is different - instead of having two dials and LCD screens above, it seems to be four dials. I've not seen this and my googling isn't bringing up anything useful. Is this a lower spec a/c or something similar? Thanks, Aled.
