'04 300m sometimes won't start/alarm blinking
The past week or so I've had a problem starting my '04 300m. I can crank no problem but it just doesn't start. The first couple of times I just had to try a second time and it fired right up. Last night, however, it took several tries to get it going.
There are no codes (using the on/off x3 method).
The only other thing is that my alarm LED (down by my left knee) is blinking - twice, pause, repeat.
Car has only 40,000 miles on it (I bought it new). Thoughts?

I have the other key that came with the car. I used it this morning and the red LED still was blinking, twice, pause, repeat.
I also noticed just a bit ago that if I do the on-off-on-off-on sequence it will stop the blinking LED. If I do it *again* it will cause the LED to start blinking twice, pause, repeat. Do it again and the LED goes off. Hmm...
The LED in question is mounted below the dash by my left knee. As far as I know this is to do with the alarm - there is a switch on the back that I can press and reset the LED if the alarm has been triggered in the parking lot or something like that. Pressing the button now has no apparent effect on this current blinking.

I have now done that. Car alarm went off when I reconnected power - d'oh! I'll report back if the car starting issue returns but I'm keeping my fingers crossed. Thx!

Where exactly is this alarm LED? I know there's one in the middle of the dashboard cover that's visible from outside the car - but I've never seen that other LED you are talking about.

Yes, I think that is correct. It was a dealer-installed option and is located down near the hood release/parking break release.
Unfortunately removing battery power for an extended time did not fix the problem.

unhook the power for alarm. see if everything works for starting the car. if its ok then you will have to find out what brand of alarm they installed. once you know the brand you might be able to search for your problem .
