Its the internal temperature sensor. On early 182s and 172s there is a small grill there. On later 182s it has the small blue nipple. Sad, but we talked about that for ages as no one knew what it was. :oops:

you sure thats what it is? my 172 had 2 grills and the second one had nothing at all behind it and the first had the little fan which draws air in over a temp sensor for the CC. Why would it need 2 sensors? Just curious.

My 172 had the grill with the fan behind it but the 182 has the nipple only.

My 182 only has the little nipple, but some of the earlier ones have the fan/grill still.

From what we could gather before the nipple replaces the old system.

early 182s (like mine for instance) have a much superior camourflaged (sp) high tech system that they dropped for a cheaper tackier blue nipple

our cars still have the same function its just that its not so noticable!

well june was around the time these new fangled blue nipples came in AFAIK.

R U sure you havent got a blue thing up by the rear view mirror in the roof?

If not you will have two mesh/holed plastic vents in the interior light assembly which is the old way?

there were some photos knocking around at some point of the two

I reckon the not so nice colours had the old style grill arrangement. ;) Keeps the price down to go with the cheap paint. ;)

So are you saying there is no temp sensor on the early cars? MInes April 04 made, june picked up.

no it was different, more blended in covert rather than some bright blue thing sticking out of the roof!

I would find the original thread with the pics in but the search function doesnt really allow me that pleasure these days!

What Dave meant to say was the original used an old fan behind a grill arrangement, the newer version is a discreet blue blip which most people dont even know is there its so tiny. ;)

yeah, maybe they changed it cos the old fan type used to sometimes make a buzzing noice on 172s and cause people stress! lol
