The ATA (anti-theft alarm) Indicator lamp does not come on when the alarm system is activated; the light has never come on. I have researched the problem with no success, and took the vehicle to a reputable Mercedes dealership who were clueless. Any suggestions to fix the problem would be greatly appreciated. The vehicle is like new with only about 9,000 miles.

 

Hello and welcome to the forum! I believe I know what you're referring to - the blinking light. I don't think that it blinks in the newer models. Other members will likely chime in with their experience as well.
