[s-cars] temp gauge error, '99 A6

[Huw Powell]

You could run it by your mechanic when it's warm and measure the temps 
with an IR thermometer when the needle goes/light starts flashing if you 
want to reassure yourself for the trip.  If it turns out that it *is* 
overheating, well it'll be where it needs to be to get fixed while you 
are away...
