When you drive your VW car, you may see one or more dashboard lights appear. At the same time, you may feel the car moving while driving. So if this happens to you, and you do not have a piece of good information about light indicators, you should check what was going on in your car. This article discusses VW EPC light car shaking.
EPC Volkswagen (Electronic Power Control light) indicator indicates that the system in your Volkswagen is faulty. That may be a sign of a problem with the throttle position, traction control, ABS control unit, or cruise control system

What Is The EPC Warning Light?
Electronic Power Control (EPC) is a warning light that illuminates when there is a problem with the power supply.
Demonstrates problems with the VW throttle system, body, drag, and cruise control.
EPC warning lights may indicate other serious problems, including Ess malfunction (engine speed sensor), air flow sensor malfunction, faulty brake light switch, faulty accelerator pedal sensor, throttle system problem, etc.
All of this will affect the performance of the car.
How Do You Turn Off The EPC Warning Light?
As previously stated, a variety of causes might cause the EPC warning lights to illuminate. To solve it, we recommend following these instructions.
- First, car owners can quickly identify the cause of EPC lights by using the OBD1 & 2 scanner tool. Connect the device to the car and perform a scan.
- It will show error codes, problems with the car system, and error codes may be the leading cause of the EPC warning light.
- Second, physically inspect the vehicle for possible damage to the EPC headlights. Physical examination involves examining the brake lights. Make sure the rear light responds as you apply the brakes.
- Next, check the throttle body for a clog of debris and carbons. If this is detected, quick cleaning of the throttle body cleaner should be sufficient. Make sure all links are properly aligned with the throttle body.
- Lastly, if there are any problems, try repairing or replacing damaged car parts.
Once the root problem has been identified and resolved, the EPC light should turn off automatically. - In some cases, you may need to reset and clear error codes using the scanner tool to turn off the light.
What’s Causing Your VW EPC Light Car Shaking?
The vibration you hear can be caused by a number of repair problems, including a bad spark plug, a bad fire in the system, and a broken engine installation.
Here are five reasons why your Volkswagen car may be moving and possible solutions:
1. Ignition Coil Fault
This vibration is noticeable when the vehicle is idle or slow-moving. An improper ignition coil can cause the engine to fail properly or to move.
You can find out which cylinder is not working properly by scanning using an OBD scanner.
Since the engine operates with fewer engine cylinders, there will be a loss of power and non-response when speeding.
Another way to check which cylinder coil is faulty is to check if the spark is missing using a spark tester.
How To Get Rid Of?
The ideal remedy is to use an aftermarket ignition coil to replace the damaged one. The shaking should stop when this is completed.
2. Uneven Brake Pads In The Rear
There are many causes for imbalance behind the brakes. It can cause conflict, loss of anointing, and many other factors.
You can quickly identify a problem with the brake pads if an earthquake occurs while you are holding your brakes.
How To Get Rid Of?
Be sure to check your rotor and make sure it is inside the details.
If the rotors are not within the specification, the next step is to adjust them in the specification or replace the new brake pad.
3. Unbalanced Tires
These are the most common causes of earthquakes in cars including Volkswagen. They are very visible during high speed.
Over time, the tires will lose their specificity. Symptoms of uneven tires include uneven air pressure, alignment problems, and more.
Unequal wheels mean that the weight is not evenly distributed throughout the vehicle, leading to movement and other factors.
How To Get Rid Of?
Locate your tire at the tire service center to adjust and adjust the air pressure and position. You should note a significant decrease in movement during high speed.
4. Engine Mount Damage
Engine mounting serves as a support for the Volkswagen engine. It helps to balance and reduces engine vibration and torque movement inside the car.
Damaged mounting means that the engine is moving too fast in the middle of the vehicle, causing a major earthquake.
How To Get Rid Of?
The solution is to repair or replace the damaged engine mount.
Replacing the support means that the engine is firmly attached to the car, and there is reduced vibration inside the car.
5. Fuel Injector Failure
The fuel injector is responsible for spraying the fuel needed in the event of a fire. The engine will burn badly when there is a shortage of fuel for combustion.
You can use a car scanner to check the fuel injection and connections. Also, check the spray capacity.
How To Get Rid Of?
If, after testing, you find that there is damage to the fuel injection, you may need to replace the fuel injection in order to function properly.
6. Damaged Unbalance Driveshaft
A damaged or uneven driveshaft will cause the car to move too fast. This earthquake is most noticeable when you are fast.
You will need to check that the drive shaft is physically broken.
When the drive shaft is broken, it is best to see a professional check and restore the driveshaft joint. It does not mean that you cannot do it yourself if you want to get your hands dirty.
How To Get Rid Of?
The best solution is to locate the damaged part of the driveshaft. Or better yet, take your Volkswagen car to a VW service technician to have your car repaired.
7. Worn Out Or Tired Engines
Aging engines will result in lower air quality and pressure and engine burnout.
This low pressure is caused by leaks in the gasket, worn pistons, worn valves, and much more.
How To Get Rid Of?
It may require a complete overhaul of the engine, but repairs to the damaged part of the engine are usually sufficient to repair the vw epc light car shaking.
Start scanning your car for any faulty engine parts and try to repair it.
Conclusion
When your car shakes as well as the EPC light appears on your dashboard, it’s not always enough to just reset the error alert on your dashboard.
We recommend that you take your car to a VW auto specialist to have a look at it and address any other mechanical issues that may be causing the EPC lights to illuminate or your vehicle to shake.
If you’re a do-it-yourselfer, the methods and recommendations given above should be enough to figure out what’s causing your vw epc light car shaking and how to fix it.
