6 Common problems with Mercedes-Benz engines and How to identify them

Driving an iconic luxury vehicle like a Mercedes Benz comes with a certain level of maintenance and upkeep, and problems can occur with any make or model of engine.

Therefore, the best thing you can do to prevent these situations is to be aware of the symptoms that engines can show.

Mileage is crucial to give a precise diagnosis of engine failures, but here there are typical troubles with Mercedes Benz engines:

1. Fuel injector problems

Pay attention to any fuel smells in the car or engine noises when driving; also, browse for rust stains or black deposits around the injectors.

Carbon, dirt, or debris can get caught on the engine valves causing the fuel to burn inefficiently and, in time, damaging the motor.

Recurring power losses and faulty sensors also may indicate that valves or their components are wearing out and need replacing.

2. Oil leaks

Low oil levels, oil stains on the floor, and a smelly exhaust are often caused by failed sealants or faulty gaskets needing replacing.

3. Misfires

Difficulty starting the car and decreasing or losing power is one of the most common motor problems and is usually related to spark plug issues.

4. Balance shaft gear failure

This issue generally indicates problems with the timing chain. If not addressed promptly, it can lead to expensive repairs and potential engine breakdown.

5. Emission of black, white, or blue smoke

Black smoke means the engine gets too little air; blue smoke shows excessive oil burning, while white smoke indicates failing cylinders.

6. Loud knock noises

Knocking sounds could indicate that the bearings are failing or have cracked.

Why buying used Mercedes engines could be a better option than new ones?

Before going to the dealership for a brand new motor, consider that used Mercedes engines for sale can be a better replacement option. Why?

Benefits of buying Used Mercedes Engines

Competitive price

Used Mercedes engines save you a significant amount of money since they cost much less than new Mercedes Benz engines. That means you can get a top-quality engine at a fraction of the price.

Model Consistency

Regardless of the model, to ensure the complete performance of your Mercedes, you should replace its original engine with something equal in quality and power. That’s why finding a used Mercedes Benz engine that matches or exceeds the quality you expect from a brand-new model is an advantage.

Keep your investment

Used Mercedes engines help to keep a brand-new-like style since they maintain the complete manufacturer’s design and OEM parts. Original engine parts make used Mercedes Benz very appealing and can increase the resale value of your Mercedes.

Safe environment

Buying a used Mercedes engine is better for the environment, as it reduces waste and requires less energy to produce them. That makes used Mercedes engines a cost-effective, reliable, and eco-friendly motor option.

Endurance & Performance

With technology advancements and proper maintenance practices, a used engine can be as reliable and long-lasting as the original.

Additionally, a used motor has already been run through its break-in period, meaning used Mercedes Benz engines are reliable as they’ve already proven themselves on the road.

Problems you can avoid when installing your used Mercedes engines at Cor Auto workshop.

Wrong setup

Installing a Mercedes Benz engine is difficult and complex work. Therefore, it should be carried out by an auto repair shop specializing in Mercedes Benz systems or German auto parts, like Cor Auto Repair in Miami, Fl.

Being unfamiliar with the design’s mechanics and specifics can lead to disastrous mistakes and waste when installing your engine replacement.

System failure

Installing used Mercedes engines by an independent repair shop or yourself may not ensure the engine functions properly and efficiently.

Improper setup increases the risk of electrical malfunction, mismatches due to damaged or wrong choice of parts, premature failure, and damaging other parts of the car.

No warranty

Performing repairs without the help of certified professional mechanics may void your warranty and return policy.

When you install your used Mercedes engine at Cor Auto, you get an extended warranty for the parts and labor.

Take chances

The risks involved in doing your repairs may be more considerable than you think, primarily because you will need the proper tools and a fair amount of knowledge about the parts to install them.

In addition, you may experience unforeseen expenses because of severe injuries to yourself or damage to the engine or its parts

  • Remove debris by flushing the cooling system.
  • Replace the old filter or clean it for better functionality.
  • Replace the oil gasket and main seal.
  • Drain the oils and replace them with the Mercedes recommended level.
