5 Reasons for Your Mercedes Oil Pressure Switch Failures

During the installation of a building’s ventilation system, regulatory appliances like the heater and AC units are installed to monitor and control temperature of the environment.  Similarly, the oil pressure switch is installed in the oil circuit unit of a Mercedes engine to regulate the car’s oil pressure and control its dashboard indicator.

Oil pressure switch plays an important role in the Mercedes car engine. It controls low oil pressure, which can result in wear and tear. It also regulates high oil pressure. It is the device that is responsible for sending signals to the car’s Engine Control Unit (ECU) for efficient engine performance.

Since the oil pressure switch plays a cogent role in keeping your Mercedes moving, you need to be informed on how to make sure it keeps functioning properly.

Recognize Why Your Mercedes Oil Pressure Switch Fails

When you drive a Mercedes, you are required to be aware of little issues that can tarnish the engineering prowess that went into its production. Various factors that contribute to the failure of the Mercedes oil pressure switch failure.

1. Oil type: The quality of engine oil that finds its way into a car is a strong determinant of its oil pressure switch lifespan. Mercedes pressure switches are sensitive to the cleanliness and viscosity of oils. So, using unapproved oils by the car brand can cause formation of dirt that clogs the pressure switch.
2. Extreme Temperature: Harsh temperature (both hot and cold) can impact the switch’s performance, despite being designed to last long. In extreme cold temperatures, the engine oil tends to thicken, making it hard for the switch to efficiently measure the oil flow. In extreme hot conditions without adequate coolans, the engine oil quickly thins out, causing it to flow easily.
3. Connection problem: The Mercedes oil pressure switch is electrically connected to the engine control unit. Therefore, corroded wires, faulty wiring, and failed sensor nodes will definitely affect its functionality.
4. Reckless driving: The way you handle your Mercedes determines the durability of the pressure switch. Frequent and rapid engine acceleration, aggressive driving on rough terrains, and abrupt stops creates inconsistency in the function of the switch. Also, moving your Mercedes before allowing the engine to warm up can cause stress on the switch.
5. Natural wear and tear: Without any complication, over time, the components of the oil pressure switch get worn out from its constant exposure to hot temperature, engine vibrations  and work pressure.

3 Signs of a Bad Mercedes Oil Pressure Switch

A bad oil pressure switch is not difficult to spot. Some signs to take note of are:

• Blinking dashboard light: a faulty switch is not capable of giving accurate readings. These bad readings will trigger your dashboard light. If your dashboard oil pressure light continually blinks after you have manually checked the oil, there is a high chance you have a bad switch.
• Inconsistent Oil Pressure gauge readings: there is cease of normalcy in oil pressure switch when the pressure readings goes from very high to very low, and vice-versa. Ensure you take note of these levels before pouring in new oil.
• Unusual noises: noise from a car engine can be attributed to quite a number of car problems. However, if after seeing a normal oil level manually and on the car dashboard, you hear tickling or grinding noise, your pressure switch might be faulty.

Preventive measures can be taken to prevent your switch getting faulty, such as regularly maintaining your oil levels, carrying out routine general car servicing, and using manufacturer’s approved oil.

If these signs are already evident, it is imperative to take your Mercedes to an Auto shop for proper diagnostic testing and oil pressure switch replacement.
