How do I unlock my Suspension Air Control Module when it is in the locked position ????

Hello, everything I read indicates that this system automatically detects and locks the suspension at the needed time. I'd suggest checking with a local shop near you with an experienced Mercedes Benz tech who may have a trick to share -- and could be a great relationship to make into the future as you have your vehicle.
