Hi, my name is***** are a couple of common problems that cause a crank/no start on the SLK. The first is a faulty crankshaft position sensor. The sensors tend to fail when hot. If the car starts when it cools down I'd suspect a bad crank sensor. The other possibility is a bad K40 relay module. The relay provides power to the control units. If the relay malfunctions, it can also cause a crank/no start condition.

Let me know if you have any questions.
