Due to its evident style and flare, you may have carefully selected a Volkswagen vehicle as your vehicle. Volkswagen vehicles are renowned for their durability, performance, affordable price tag, and attractive streamlined style.
But the EPC warning light may come on, and the car will tremble. A rough brake surface, a defective ignition coil, imbalanced tires, a problematic fuel injector, or a problematic engine mount could all be to blame for the shaking issue with Volkswagen EPC light vehicles.
Despite the worrying appearance, we have identified the issue and outlined the solutions for the EPC light and shaking problem. So let’s start right now!
What Does EPC Light Mean For VW?
The actual meaning of EPC, which stands for “Electronic Power Control,” is a little more complicated. But above all, you need to understand what the EPC light means. EPC, or Electronic Power Control, is exclusively found in vehicles manufactured by the Volkswagen group, Bentley, and Audi.
In contrast to warning lights with a clearly defined area of the issue, an EPC light can involve several systems and components. When this specific signal illuminates, it typically denotes that the traction control, throttle body, and cruise control are malfunctioning.
Symptoms Of The EPC Lightening
The EPC light will illuminate when something goes wrong with the engine or a few other connected items. The ECU limits throttle usage in this situation to prevent further damage. The EPC monitors many other systems.
Thus, a few additional warning lights might also come on. The “Check Engine Light” is the most common sign that the engine is not fully functional.
The ECU can also disable the stability and cruise control systems, which will light up the associated dashboard indicators. The steering wheel and the ABS sensors are some other warning devices. A broken throttle body, brake pedal, or power steering could be the culprit in severe circumstances.
Using an OBDII scanner is the only way to determine the cause of the issue. If you don’t have a scanner at home, bring your automobile to a service shop. The mechanics will connect the scanner to the EPC system to identify the fault code.
They will then make the necessary repairs using the code as a guide. The offending code must then be eliminated to get everything back to normal.
What Is EPC Light In Volkswagen?
The electronic power control light is linked to the throttle system in Volkswagen vehicles like the Atlas and Jetta. The EPC light can turn on if your Volkswagen has problems with the throttle system. Informing you so you can arrange for the necessary maintenance and repair.
Your Volkswagen’s electronic stability program could malfunction and turn on the EPC light. The Volkswagen EPC light often signifies that the vehicle needs additional inspection at a VW-authorized service facility.
Is It OK To Drive With The EPC Light On?
No, even if we are competent drivers and can drive the car and control it well, the engine won’t be healthy. Our engine could sustain harm if the EPC warning light is on and we continue to drive. Even if the machine didn’t cause the problem initially, the stress we put on it would eventually wear it down.
After an issue is discovered, Volkswagen and other vehicles with EPC warning lights frequently turn on limp mode. Although this makes our automobile theoretically safe to drive, the limp mode should only be utilized occasionally as it reduces harm to the car at the expense of power.
Causes For EPC Lightening
Like a Check Engine light, an EPC code on a Volkswagen Jetta may indicate a minor or more significant issue. When the drivetrain computer notices a reading beyond the typical range for a system, a fault code—or an EPC code in the case of Volkswagen vehicles—is stored in the computer.
In this instance, the EPC sensor gave the computer data that caused the computer to instruct the vehicle to go into limp-in mode.
There are several potential causes, including:
- Timing errors, fuel metering issues, or exhaust system issues.
- Malfunctioning speed sensor for the engine.
- Other sensors, such as the mass airflow sensor, the crank or cam position sensor, and even the brake light switch, may have problems.
- Traction control problems.
- Vehicle stability control problems.
- Issues with the cruise control.
- Difficulty with the throttle.
How Can I Fix EPC Warning Lights?
The EPC warning light impacts numerous areas of the car’s functionality. To solve this problem, adhere to the following procedures.
Equipment for OBD1 and OBD2 scanners is the first item you require. The device must then be placed in the vehicle and scanned after that. Several error codes are saved in the control unit and are displayed on the scanner when the EPC warning light turns on.
Next, physically check for any more damages that would cause the EPC warning light to illuminate. Checking the rear light and brake light is also necessary. Make sure they are all in working order before continuing.
The next step is to look for dirt, debris, or carbon buildup in the vehicle’s throttle body. If you find any of these, you must clean them out. Thorough cleaning can be aided with a throttle body cleaner. Ensure that every connection is made appropriately.
Fix the problems and replace anything that has to be replaced after the investigations are finished. The EPC light will automatically turn off when these are finished.
How Do I Reset My VW EPC Light?
The EPC light can be reset on several models of Volkswagen vehicles using various techniques. As long as the problem that triggered the EPC light hasn’t been found and resolved, we advise against doing this.
Whether it’s a Volkswagen EPC light or a Check Engine light on a different make of car, these systems are designed to take a lot of the guessing and deduction out of professionals’ diagnosis and repair.
The code that initially activates the EPC light can be accessed with a tool. Once the professional has analyzed the code and read between the lines, they can find the troublesome part or system and repair it.
Some problems can also be resolved on your own. The EPC warning light will go off once the issue has been resolved, whether by yourself or with the help of an expert.
We should take all reasonable steps to heed the caution that the car issues. One of the available warning systems we have is the EPC warning light. It will, nevertheless, be the most crucial in the case of car trembling.
People willing to fix their automotive problems should do it right away. Either use different do-it-yourself fixes or take the automobile to a mechanic. However, be careful to drive the car as little as possible to prevent more harm from internal operations.
