Mercedes Benz Won’t Start?
Have you noticed that your older ML (163 Chassis) sometimes refuses to start? Have you started the car in your driveway, driven to the store and come out after a short time to find that the your car won’t start again right away? Does the problem happen intermittently? Is it becoming more frequent?
This is a common complaint for older MLs and the other Mercedes Benz models mentioned below. And the problem could likely be your Crankshaft Position Sensor.
Your vehicle’s Crankshaft position sensor’s job is to relay the exact position of the crankshaft to the engine control module for correct engine timing, fuel injection, ignition, etc. Without it, your car will simply not start.
If you live in warmer climates, such as Sarasota, Florida, summer months can cause your vehicle to frequently run above normal operating temperature (normally around 80 degrees Celsius, although this can vary). The extreme heat conditions can cause the circuit inside the crankshaft position sensor to expand and lose connection (resulting in an open circuit). When this happens, the sensor cannot operate until the engine cools down and the circuit closes (contracts with loss of heat). Which is why the car will likely start again after sitting for 30 minutes or so. Over time the circuit will cease to close even after cool down.
Because this is an intermittent problem, mechanic scan tools and diagnostic equipment may not detect any trouble codes. Diagnosis can be difficult if the mechanic is not experienced and familiar with common Mercedes Benz problems.
I am a Master Certified Mercedes Benz technician with more than 16 years of dealership experience and training in all facets of vehicle maintenance and repairs.

As an example my fee to diagnose your problem and replace your crankshaft position sensor on your V6 or V8 (non AMG) will be around $243.40 including parts and labor, although this can vary depending upon vehicle. 4cyl will likely be a bit less, while V12s and AMG models will be a bit more.
