In my mercedes parts book, it shows an arrow pointing somewhere under the hood for the engine code, but I've looked high and low under there and for the life of me I can't find it.
I can get a compressor on ebay for pretty cheap....but will it fit??? I have a couple friends at the Dealership...I'll check with them to see if they can tell me where to find my engine group number...apparently it's more than just 103.942
