I replaced my outside temp sensor a while back. I still get the occasional -1 or 32 with a snowflake on the temp display when its in the 50s and 60s outside.<p>What the hey?<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/cool.gif" BORDER="0">

Not sure if it would be the same issue, but we recently had that on the girlfriend's S40 and it turned out to be the door harness. It could be the same thing since the wiring for the sensor is part of that harness.

Re: (phuz)

With temps in the 90s and the temp sensor interfering with the air conditioning, I heated up my shop lamp and held it under the driver's side mirror (where the temp sensor is) with the key on until the temp display began to show a response. Turned the key off. I been driving in air conditioned comfort since. Coincidence? We'll see.<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/cool.gif" BORDER="0">

Re: (Steely)

Is the outside temp sensor related to the air conditioner? Lately it's been showing 32F and the snowflake when it's 85F outside. Also sometimes the air runs warm instead of cold.

Re: (MakoCSH)

As an update for all you DIYers:<p>The shop lamp method didn't work for long. However, Problem Solved! <p>Contrary to what the Haynes manual says, there are TWO Outside Temp Sensors, one in each of the side rear view mirrors under the little nipple you see sticking down. I removed the mirror to get to the passenger side sensor, popped it out with a bone tool and cleaned it with Q-tips and alcohol. Voila! Correct outside temperature readings and correctly functioning Air Conditioning<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/cool.gif" BORDER="0">

Re: (Steely)

I thought there was only one sensor located on the passenger side (like you said) and the driver side nipple is just a dummy piece to make the car look symmetrical. <p>But what do I know.

I replaced that sensor about a year ago. I read that there was one in the passenger side (on another forum), pulled the mirror - lo and behold there's another sensor on the passenger side. Both are wired and, apparently, both are required for the CCM to function properly. Mine's still working.<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/cool.gif" BORDER="0">
