FAQs—Mercedes Benz SLK32 AMG
The engine of my Mercedes Benz SLK32 AMG cranks but doesn't start until after I waited for a bit. Also, after a few attempts to start my car, the Red SOS light in the upper console started to blink. What's going on with my car?
Your Mercedes Benz SLK32 AMG needs to have three things in order to start and run: spark, fuel, and compression. If you did not see any spark, then the crank position sensor might be bad, the ignition module or PCM might be faulty, or the ignition circuit might have a problem. It might also be caused by a faulty park/neutral safety switch, a bad ignition coil, or wet plugs or plug wires. It is also possible, though less common, that your starter might be worn and thus draws so many amps while cranking the engine that there's not enough juice left to properly power the ignition system. This is usually caused by a week battery or loose or corroded battery cables. You can use a scan tool and look for error codes in order to find the root cause of your car's no-start condition or visually inspect each component.
My Mercedes Benz SLK32 AMG's windows stopped working at the same time. What could be causing this?
The first thing you need to do for electrical problems like this is to check if the fuse is blown, which is the case if nothing happens at all when you push the window button. Try pushing it again and listen for the motor groaning and the glass quivering like it wants to move. If neither of these happens, then you have a burnt fuse that needs to be replaced. However, if your fuse is working fine, then you likely have a mechanical problem. To diagnose the problem further, you need to get a schematic of your Mercedes Benz SLK32 AMG's electrical system and a voltmeter or test light. Starting at the fuse panel, follow the wiring to the switch, then from there to the motor, while running your voltmeter or test light on it. You might find a loose or corroded connector that's interrupting the voltage to the motor. The switch itself might be bad, which you can confirm if the driver's door switch won't open the right door but the switch in that right door does.
I replaced the battery of my Mercedes Benz SLK32 AMG and now some of the electric components do not work. How do I fix this?
Replacing, and even disconnecting, a battery on the Mercedes Benz SLK32 AMG may cause starting issues, drivability complications, and other problems, which is why you need to proceed with caution when taking out the battery or installing a new one. When disconnecting your car's battery, several problems may arise aside from what you're experiencing now. In order to avoid any problems from happening, make sure that you disconnect the battery properly and with care. If you don't feel confident about this task, ask for help from a friend who's more experienced with car repairs, or from your trusted mechanic.
