I'm looking for an Air Bag Module, that is discontinued, from a parts car or something (5102756AA) for a 2006 Crossfire Limited Roadster. Any leads are appreciated. Thanks!

 

Do what I did: Give up. I sourced two of them, first one was wrong year, second one would not program when I sent it to SOS, they said it was unresponsive.

 

I replaced mine recently. Do a search on eBay for Mercedes part no 0018200826. These modules were used on many different Mercedes cars from the same time. Just buy a working used one. When you replace it, you'll need to find someone with Mercedes Star DAS software to set it up for the options your car has (you can read them from the old module) and do a reset.
