The saga continues...

Yesterday morning the turned over and over with no start.

I have found that there are actually two different ways the lights on the rearview mirror flash:

1) Both red and blue at the same time = low key battery

2) Red and blue alternatly = unauthorized start

#2 has been the problem all along!!

For some reason when it is cold outside the car does not recognize my key.

Any help is appreciated...

Dan,

You may want to check any grounds associated with the reciever in the mirror. you may have one that is some what loose and with the cold temps is no longer making a connection. I wish I could point you to where those grounds are, maybe one of the pros could send you a wiring schematic. Just a thought.

Last winter, my first year of ownership of my E300 I would also get a check engine light every once in a while when it got to about 8F. After a few miles they went away. Had the codes scanned at my Indy and they turned out to be emissions codes relating to the EGR system. The code usually dissapeared within 100 miles, but usually a lot less.

What a nightmare. I've never really liked those electronic keys - at first they seem kind of neat but you quickly realize they are about 4X the size of an old syle MB key. This makes it pretty easy to find the key on the keyring but its mighty uncomfortable to just drop the keys in your pants pockets, and of course as you are discovering when problems arise with the key/security system you pretty much have to be a EE to troubleshoot the damn thing.

I think you are going to have to wait for another 10F night and drop the car off at the MB dealer the night before with instructions for them to try to start the car first thing in the morning. I'm sorry to hear you are still having problems, good luck.

Dan another thought, try starting first thing on a cold morning with one of the non-electronic key's. If it will start then I would toss the electronic key in the trash, like Tim said it is too big for the average pocket anyway.

Thanks, guys.

I tried the regular key when I had troubles last. Both of my electronic keys and the regular one as well as the valet key did not work at starting the car. This is why I think it must have something to do with the receiving end of things.

Does anyone know about the mechanisms there?
