C240 faulty LF signal

I've tried everything, changed the light bulb, check the fuse, check the flasher and still no resuts, please help.......... also, do I have to go the dealer for a electronic keyfob replacement or there's a way to reprogram another key without paying the $250.00 at the stealership. The reason I ask is, I've a additional key from another car and would like to program it to use in my car(2002 C-240 (W203). Thanks for any all the help you guys could give me...

I can't help with your turn signal but is it only the left front one not working?

You absolutely cannot have some other key programmed to your car. It must come from an authorized MB dealer who orders them directly from MBUSA. The new key will already be programmed to your car when the dealer receives it.

the turn signal problem is the connection in the connector, there are a set of wiring updates that add a seperate ground for the signal bulb. they are pretty cheap and someone with general knowledge should be able to install them..le me know if you need the part number for the wiring updates
