Does Your Mercedes Have a Bad Starter?

Did it ever happen to you that you rotate your car keys to start the Mercedes, but there’s only silence in return?

 

When you start a Mercedes engine, it produces a cyclic whir-whir-whir sound that every driver is used to. But there comes a day over years of automobile ownership when you’ll hear discrepancy in this sound. It’s the most prominent sign of a bad starter. If you suspect the same, read on to know all about a bad engine starter in Mercedes and how to fix it with a quality used engine.

 

3 Signs of Starter Failure in a Mercedes Engine 

 

  • Silent Engine: You turn the key to start the engine, and nothing happens, it’s a clear starter issue. Your engine starter may have defaulted or there could be some electrical problem.  
  • High-Speed Whirring Noise: If the starter is making a noise, but it’s the usual one, that’s also not a good sign. If your engine starter is making a high-speed whirring noise, it means it’s not engaging the flywheel. This could be a solenoid or a Bendix drive problem and need fixing.
  • Grinding or Clattering Sound: The third scenario is if the starter is partially engaging with the flywheel. It makes a clattering sound but doesn’t start the engine. The starter is usually not fully engaging the ring gear and the engine is not turning over.

 

Causes of a Starter Failure

 

Even though starters are made with reliable materials nowadays, some factors can still cause them to malfunction. Following are a few of them.

 

  1. Age: First on the list is age. Even reliable auto parts can’t last forever as they lose efficiency with age. Mileage is also a relative factor. Putting more miles on an engine in a short time aggravates this.
  2. Cold Winter Climates: As the engine takes a bit longer to start in winter, that pressure is born by the starter. Repeated attempts at starting the engine with no response lead to starter wear & tear. That’s why Mercedes owners eventually look for used Mercedes engines for sale.
  3. Abusive Starting Techniques: if you’re resorting to abusive starting techniques, you’re damaging your engine starter. Like driving habits, starting techniques also impact the functioning of engine components, including the starter.
  4. Engine Oil Leaks onto the Starter: Leakages are never good. An engine oil leakage into the starter housing and coating the commutator area of the motor shaft can damage the whole block. This will degrade the ability of the starter to crank the engine.

 

Solution—Engine Replacement 

 

If you are experiencing an engine starter problem, the most suitable solution is to get an engine replacement done. You can also replace the starter itself. But if the problem has been consistent for a while, other parts may be damaged, too. So, getting a used Mercedes engine with a warranty and functioning components will help you start your Mercedes again and with ease.
