Hi all, I'm a newbie on here but am very frustrated. My SLK was working just fine yesterday but today it won't start. All dash lights work, radio works, lights work etc etc all power works, including windows, but when I turn the key nothing happens, engine won't crank. I don't get any error codes, nothing. I do hear an audible click in the engine compartment when I turn the key and then...nothing. Battery voltage is good at 12.7, battery in FOB is fine. It rained heavily last night and the car was under the carport (moisture problem?). I have not had any problems with this car and I bought it in December of 2009. Love the car! Can anybody help?
