Outside Air Temp module bad
 

Hi everyone!

Where can I get an OAT module (part # 124 542 02 27) other than the Dealer? I have tried all the parts houses with no luck. :confused:

Thanks

If you have the part number, I will assume you can see the back of the temp display to determine if it is five pin or four pin.

I just checked Ebay and there are a couple of them being offered. Both pin types for your W124. Both however display farenheit temp. May be what you are looking for.

Go to Ebay motors. Under the parts and accessories section click on car and truck.
Then in the search bar type in Mercedes outside temp. Relatively easy to replace. I changed out mine that read celcius and put one in that read farhenheit. Just be sure when you are browsing through Ebay, or anywhere else, that the display appears perfect. No evidence of heat damage. Happy hunting.

Thanks cdplayer!

I did not even think of looking on e-bay. I had my cluster out today and I have in my hand the OAT module and it has the 4 pin connector but all the ones for sale are the 5 pin style. However, they say tou can just splice in the 5 pin connector to your wiring.

Hope that will work.

When you get to Ebay and see the outside temp displays offered, the second display for the W124 has instructions for a 4 pin hookup. Also arrow down to "Ebay Stores for the W124. This guy offers a 4 pin convertion plug. It's a little pricy at $70 but may work.
