The Mercedes you own is packed with innovative technologies and features. The challenge of owning such a high-end vehicle is that, you have to provide it with specialized care and attention – particularly when the check engine light comes on. Today’s blog post is about the leading reasons behind the illumination of CEL in Mercedes cars. The post also discusses the benefits of having the issue handled by trained professionals.

Here’s What An Illuminated CEL Could Mean

#1- Emission system fault

Modern cars come equipped with all sorts of different emissions control devices such as catalytic converters, evaporative emission control (EVAP) systems, and exhaust gas recirculation (EGR) systems, to comply with regulations put forth by pollution control authorities. If for some reason one of these systems ceases functioning, the onboard diagnostic system would activate the check engine light to alert the driver of the issue.

#2- Defective sensor

Sensors have become integral components in modern-day vehicles. They help the vehicle with many different things; ranging from performance enhancement to emissions control. MAF, O₂, TPS, MAP, engine coolant temperature sensor, CKP, CMP, wheel speed sensor, etc. help the engine management computer to monitor and regulate different aspects of the engine operations. If one of your Mercedes’ sensors acts up, not only will its performance be impacted, but its check engine light will also come on.

#3- Engine troubles

If there is something off with your Mercedes’ engine and its performance is compromised, it can also result in the illumination of check engine light. Anything that can impact the timing of fuel combustion within the cylinder– such as issues with the ignition system parts, fuel delivery system parts, or air intake system parts- can set off the check engine light. Those issues can also contribute to misfire, rough idling, stalling, and numerous other performance-related issues.

#4- Transmission malfunction

The transmission unit of your Mercedes essentially orchestrates the transfer of engine power to the wheels- that to be in a very controlled manner. As with any other mechanical parts of your vehicle, the transmission unit can experience issues such as erratic shifting, slippage, among other troubles. These are among the things that can contribute to the flashing of the check engine light.

#5- Fluid-related issues

If your Mercedes is running low on motor oil, coolant, or other critical fluids it may also contribute to the flashing of the check engine light. Fluids aid your vehicle with many different things; ranging from lubrication to cooling of important parts. If they become contaminated or leak out, not only will the performance of your vehicle be impacted, but the check engine light might also come on.

Why You Should Trust A Trained Mechanic

#1- Specialized diagnostic equipment

When it comes to diagnosing and fixing a complicated issue in a top-tier car like Mercedes, you will need specialized diagnostic equipment. Such tools are only available at service centers that specialize in European cars. Factory trained technicians with the help of these high-end tools can perform comprehensive diagnostics on your Mercedes to get to the root of the issue that resulted in the illumination of the check engine light.

#2- Expertise in Mercedes technology

Cars manufactured by Mercedes are technologically superior to standard vehicles that you see on the road. Ordinary mechanics with conventional repairing tools can’t be expected to handle complicated mechanical issues in such high-end vehicles. If your Mercedes is acting in a weird manner and its check engine light is on, it is recommended that you have it checked by trained technicians who have undergone extensive training and completed various certification programs.

#3- Quality genuine parts

Another benefit of hiring a factory trained mechanic to reset your Mercedes’ check engine light is that only genuine OEM parts will get used in the repairing process. The benefit of using quality genuine parts in the repairing process is that they will enhance your vehicle’s reliability and durability.
