The technologically advanced BlueTEC engines used in Mercedes Benz diesel cars, SUVs, and sprinter vans are a few of the most advanced diesel engines in the world. The usage of the high-pressure fuel injection system and geometry turbochargers stimulates excellent combustion. This arrests the emissions along with providing better power output. The cloud of black smoke while accelerating has become history because the soot is trapped by a diesel particulate filter (DPF). Advanced engineering has enhanced the demand for “Mercedes Benz diesel engines for sale”.
Additionally, to reduce NOx emissions, the diesel exhaust fluid (DEF) is injected into the stream of exhaust gasses. Therefore, Mercedes successfully meets the highest emission standards along with providing powerful performance with great fuel economy. But as we know everything has good and bad sides both. Let’s get familiar with the drawbacks of the Mercedes Benz diesel engine.
Following are some of the problems that are observed in many Mercedes Benz diesel models such as E350, ML350, GL350, R350, Sprinter, R320 CDI, and Blue Tec models.
Diesel Particulate Filter (DPF)
The timely utilization of DPF makes it compulsory to get it emptied as soon as DPF starts to trap or holds soot. The process of emptying the PDF is known as regeneration. It’s an automatic process in which engine computers’ exhaust gasses are increased over 630 degrees Celsius. The rise in temperature burns out the soot particles. But if your engine is not working properly then it might not sustain the automatic regeneration process.
Faulty temperature sensor, swirl flap motor, or EGR valve are a few of the reasons that arises the issue. If your DPF is faulty then it could be fixed but if your engine is problematic, then you should start thinking of “Mercedes used engines with warranty”.
PDF Exhaust Pressure Sensor
To calculate how much exhaust flow could be contained by the PDF, different models of Mercedes Diesel cars use DPF exhaust pressure sensors. The jammed PDF will eventually restrict the flow. Just like any other sensor, this too can be problematic because of several reasons. Sometimes, even the incorrect readings can represent a faulty PDF state.
The non-workability of the sensor may be diagnosed when you experience a substantial loss of power. Luckily, the DPF exhaust pressure sensor is not that expensive to be replaced. Upon noticing the issue, you must get it checked and take the necessary steps to avoid the situation of finding “Mercedes Benz diesel engines for sale”.
DEF Heater
Almost in every BlueTEC Mercedes vehicle diesel exhaust fluid is utilized, which is popularly known as AdBlue. These fluids tend to freeze in cold weather which is why an electric heater is used. Eventually, the heater burns out with time. Whenever you notice the “check engine” light illuminated, you should immediately take it for professional help. You should never ignore the symptoms of your Mercedes cars if you want to bypass the circumstance of exploring “used Mercedes engines for sale”.
Final Thoughts-
First and foremost, a habit you must apply in your life is to avoid guessing whenever you notice any kind of issue or abnormalities in your Mercedes Benz diesel cars. The time wasted in guessing could enhance the impact of the issue and ultimately damage the engine or any parts completely. Be aware of the codes before replacing any parts of the Mercedes diesel cars.
Though Mercedes Benz has excelled in providing the best combination of luxurious comfort and delightful driving. Yet, you have to be prepared for any fallout. After all, it’s a machine, timely breakout is unavoidable. Your slightest ignorance could hamper your car and you might find yourself looking for “used Mercedes engines for sale” very soon.
