Understanding Car Shaking while Driving:

Cars can shake for many reasons, especially when driving or accelerating. Here are some common causes:

  • Engine Problems: Misfiring engines cause the car to shake. It’s often due to spark plugs or fuel injector issues.
  • Brake System Issues: If your vehicle shakes when you apply the brakes, it might indicate a problem with your rotors or brake pads.
  • Tire Troubles: Unbalanced tires can make the whole car tremble. Regular tire maintenance is essential in preventing this issue.
Cause of Car ShakingPossible Solution
Engine ProblemsCheck and replace spark plugs if necessary
Brake System IssuesInspect and repair brake system
Tire TroublesBalance your tires

It’s important to understand that these are just possible reasons and solutions. Always consult a professional mechanic if you’re experiencing any severe automotive issues.

Possible Reasons for Car Shaking during Acceleration:

If your car shakes during acceleration, several factors may be at play:

  1. Wheel Alignment Issues: Misaligned wheels can cause vibration, especially when accelerating.
  2. Tire Imbalances or Damage: Uneven tire wear, imbalances, or damaged tires can lead to shaking.
  3. Faulty Spark Plugs or Ignition System: Misfiring cylinders due to worn spark plugs or ignition issues can cause vibrations.
  4. Transmission Problems: Issues in the transmission, such as a damaged torque converter, may result in shaking.
  5. Engine Misfires: Problems with fuel delivery, air intake, or faulty components can cause the engine to misfire during acceleration.
  6. Drivetrain Problems: Faults in the driveshaft, CV joints, or differential can lead to shaking.

Addressing these potential issues through inspection and necessary repairs can help resolve the shaking during acceleration.

Identifying the Source of the Problem:

When your Audi shows an EPC light and experiences shaking while driving or accelerating, it could be due to several reasons:

  • Faulty Ignition Coil: This is a common cause. The ignition coil helps ignite fuel in the engine cylinders.
  • Throttle Body Issues: If there’s a problem with your throttle body, it can make your car shake during acceleration.
  • Problems with Spark Plugs: Old or damaged spark plugs can affect engine performance and lead to shaking.

Before you start working on any fixes, you’ll want to identify which of these issues is causing problems. Here are some steps:

  1. Check Engine Light: An illuminated check engine light often accompanies EPC light when there’s a fault in the ignition coil or spark plugs.
  2. Perform an OBD-II Scan: Use an On-Demand Diagnostic tool for detailed information about what’s wrong.
  3. Physical Inspection: Inspect your throttle body for signs of wear and tear that might indicate a need for replacement.

Spark Plug ProblemsPoor fuel economyChange spark plugs

Remember: Always consult with a professional mechanic if you’re unsure about identifying or fixing these issues yourself!

Steps to Fix Audi EPC Light and Car Shaking Issues:

Follow these steps to troubleshoot and potentially fix the issues of your Audi’s EPC light coming on and car shaking while driving or accelerating.

1. Checking and Replacing Faulty Spark Plugs:

Your Audi’s EPC light might flash, and the car may shake while driving or accelerating due to faulty spark plugs. Here are some steps you can take:

  1. Locate the Spark Plugs: In most Audis, you’ll find them under the hood on either side of the engine block.
  2. Inspect for Damage: Look for any physical damage like cracks or burns on your spark plugs.
  3. Test Using a Multimeter: Set your multimeter to resistance mode (Ohm setting), connect it to each end of a spark plug, and check readings.
    • Good Spark Plug: 4-7k Ohms
    • Bad Spark Plug: Readings outside this range

If damaged or bad readings are detected, replacement is necessary:

  1. Remove Old Spark Plugs: Use a spark plug socket wrench to remove each faulty one.
  2. Install New Ones: Apply anti-seize compound on threads of new spark plugs before installing them using hand first then tightening with wrench.

Remember that specifications vary so always refer back to your vehicle manual!

Here’s an idea about what costs could look like:

ItemAverage Cost
Single Spark Plug$6-$15
Full Set Replacement Labor Costs$40-$150

So don’t ignore that shaking feeling when you’re driving your Audi – It just might be time for new spark plugs!

2. Inspecting and Cleaning Dirty Air Filters:

Dirty air filters can cause your Audi’s EPC light to illuminate, followed by shaking while driving & accelerating. Here are some steps for inspection and cleaning:

  1. Locate the air filter housing: Typically found in engine bay, usually a black box with clips on the side.
  2. Remove the old filter: Unclip housing lid, pull out dirty filter. Note: Pay attention to orientation of old filter before removing it.
  3. Inspect for dirt and debris:
    • Clean Filter: Minimal dust/debris
    • Dirty Filter: Clogged with thick layers of dirt

  1. Clean or Replace if necessary: If lightly soiled; clean using vacuum cleaner or compressed air (from inside out). For heavily soiled filters; consider replacing instead.


  • Always replace lid securely after cleaning/replacing filter.
  • Never run engine without an air-filter installed.

Take care of these simple maintenance tasks regularly to prevent unexpected car issues during acceleration!

3. Examining Fuel System Components for Problems:

When the Audi EPC light comes on and your car shakes while driving or accelerating, it’s often a fuel system issue. Here’s what to check:

  • Fuel Injectors: Dirty or clogged injectors can cause misfires, leading to shaking. A professional cleaning can help.
  • Fuel Pump: If it’s failing, you’ll notice performance issues when accelerating. Listen for strange noises from the back of your car.
  • Fuel Filter: Replace if dirty or old. Blocked filters restrict flow and impair acceleration.

Here is a simple table outlining each component, potential problem, solution and tools needed:

It’s important to remember these are only potential solutions – always consult with a qualified mechanic before attempting any repairs yourself.

Seeking Professional Help if Issues Persist:

If your Audi’s EPC light remains illuminated and the car continues to shake while driving or accelerating, it’s time to seek professional help.

  • Visit a Certified Mechanic: Don’t ignore these symptoms. An experienced mechanic can diagnose and fix the problem quickly.
  • Use an OBD2 Scanner: If possible, use an OBD2 scanner before visiting a mechanic. This will give you some insight into what might be causing the issue.
