Dear Toby:

While I don't have a clear answer to your questions, I do have the same car with the red/green lights under the rearview mirror.

Unfortunately when I got the car (auction) it did not come with any remote but a friend of mine got me one from another Benz but did not know what model whatsoever.

Now the scary thing was that when I change the batteries on the remote it worked immediately but just for three days.

Let me ask you, what kind of remote do you have?

Can you open the trunk with it?

Please advice.

Happy new Year!!!
