Assume you’re driving down the interstate in your Volkswagen and notice that when you accelerate, your car begins to shake violently. Your EPC warning lights will also turn on. So, what exactly do you do?
The VW EPC light car shaking will be discussed in this article, as well as how to remedy it.

VW EPC light Car Shaking; Why?
When something is wrong with the vehicle, the identical dashboard light operates in a few different ways. So, what exactly are those kinds of signs and what do they mean?
1. Engine Mount Damage
The Volkswagen engine is supported by the engine mount. It enhances vehicle balance and reduces vibration and torque motion in the engine.
The most obvious and worrying sign of a broken engine mount is when the engine swings uncontrollably within the automobile while driving.
It’s quite substantial, and any movement within the engine compartment should be noticeable. You’ll notice it wobbling from side to side when turning or coming to a halt.
2. Tires That Aren’t Balanced
An imbalanced tire can create a significant steering wheel shake, causing the steering wheel and, in certain situations, the entire car to tremble. Tires that are misaligned, damaged, or of poor quality can potentially be the cause.
One example of a difficult to notice condition is the light suspension, which causes the wheels to be out of balance with the counterweights.
If these issues are not addressed, damage to the struts, shocks, grooves and other steering and suspension components will result.
That’s not all, though. Driving on worn-out tires that have become under-inflated is extremely dangerous. Even in dry conditions, they can’t grip the road properly, making your car sound like a lawnmower and causing it to wobble.
3. Dash Lights Aren’t Used Anymore
It’s safe to presume that if the dash lights are completely dark, the issue is electrical.
A blown fuse, which is designed to protect circuits in the event of an electrical surge, is the most common cause. However, it’s possible that the problem is caused by deeper wiring faults.
These issues may cause the fuse to blow again, and they may remain even after the fuse has been replaced.
4. Ignition Coil Fault
This form of shaking is visible when the car is stopped or driving slowly. If the ignition coil fails, the engine will misfire or tremble.
If you really want to figure out why your check engine light is on, you’ll need an OBD2 scanner.
5. Fuel Injector Failure
The fuel injector is in charge of injecting the fuel required for combustion. When there isn’t enough gasoline injected for combustion, the engine will misfire.
Check for fuel injection pulses and connections using the car scanner. Check the spraying power as well.
6. The Driveshaft That Is Damaged Or Out Of Balance
If the driveshaft is cracked or unbalanced, the automobile will shake violently. You’ll notice the tremor the most when you accelerate. You’ll need to inspect the motor shaft to see whether it’s broken.
7. Uneven Brake Pads In The Rear
You may have a problem with your brake pads if your car begins to shake while driving.
Uneven rear brake pads can be caused by a number of circumstances. Friction, a lack of lubrication, dirty or rusted brake rotors, and a number of other factors could all be to blame.
Brake pads may also wear down over time due to normal wear and tear. Your brake pedal is also squeaking because of this.
Furthermore, when the steering wheel shakes at high speeds, one of the things to inspect is the brake caliper. This is because as you drive faster, the vibrations will get more intense.
There will even be a burning odor as you come to a halt.
How To Fix If VW EPC Light Car Shakes?
As previously stated, a variety of causes can cause the EPC warning lights to illuminate. To solve it, we recommend following these instructions.
1. Change Brake Pad
If the thickness of your rotors varies, brake pads will wear out faster. As a result, you must verify that your rotor is in perfect working order.
While checking your brake control unit, if the rotors are out of order, you’ll need to either repair them or replace them with new brake pads.
2. Repairing Or Replacing The Engine
If you think your engine is moving while you’re driving, get it fixed right away.
The engine damage mount can be repaired or replaced to fix the problem. You will notice less vibration within the vehicle during a drive if you do this.
3. Replace Fuel Injectors
If you discover damage to the fuel injectors after inspecting them, you may need to replace them in order for them to function properly.
Take your car to a mechanic to be checked for fuel leaks, fuel pressure, and proper fuel mixing, which may necessitate the use of costly devices to ensure the blockage is removed.
4. Replacing The Broken Drive Shaft Portion
The best solution for your car is to replace the fractured drive shaft part. You can then take your Volkswagen to a Volkswagen service center to get it repaired.
Frequently Asked Questions
Here are some frequently asked questions about VW EPC light car shaking:
1. Why Is My Car Shaky And The EPC Light Illuminated?
Electronic Power Control is abbreviated as EPC. When this light comes on, it usually means there’s a serious problem with the fuel or ignition system.
The automobile vibrating, on the other hand, could indicate a vacuum leak or even broken motor mounts that require replacement.
2. How Much Does A VW EPC Light Repair Cost?
You’ll have to pay an average of $124 to $214 to repair a flashing Electronic Power Control (commonly known as the EPC), but only if the throttle body is damaged.
The situation is most likely to be resolved by just resetting the light. An EPC light on a Volkswagen Jetta costs roughly $200 to repair.
3. What Is The Procedure For Resetting The VW EPC Light?
To resolve the EPC light on your own, follow these steps:
To begin, start the car normally. When the vehicle restarts, depress the gas pedal all the way to the floor until the engine stops.
This is effective in some situations. While performing this technique, it’s also a good idea to inspect the electrical connections on the throttle body.
Conclusion
When your car shakes or an 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 car expert 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 the VW EPC light car shaking and how to fix it.
