Why the Check Engine Light Comes On
Before we dive into resetting the light, it’s important to understand why it turned on in the first place. The check engine light is part of your car’s onboard diagnostics system (OBD2), which monitors engine performance, emissions, and various sensors. When the system detects a problem—whether it’s a misfire, a faulty oxygen sensor, or a loose gas cap—it stores a diagnostic trouble code (DTC) and illuminates the light.
On a 2013 VW CC, common triggers include:
– Loose or damaged gas cap
– Faulty oxygen (O2) sensor
– Mass airflow (MAF) sensor issues
– Catalytic converter problems
– Spark plug or ignition coil failures
– Evaporative emissions system leaks
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time. That’s why it’s crucial to diagnose the issue before attempting to reset the light. Resetting without fixing the problem is like turning off a fire alarm while the house is still burning—it doesn’t solve anything.
Tools You’ll Need
To reset the check engine light on your 2013 VW CC, you’ll need the right tools. Here’s what we recommend:
OBD2 Scanner
This is the most reliable tool for reading and clearing trouble codes. Look for a scanner that’s compatible with Volkswagen vehicles and supports OBD2 protocols. Popular options include the BlueDriver Bluetooth Scanner, Autel MaxiCOM MK808, or Foxwell NT510 Elite. These devices can communicate with VW’s proprietary systems and provide detailed diagnostic information.

Smartphone or Tablet (Optional)
If you’re using a Bluetooth OBD2 scanner, you’ll need a mobile device with a compatible app. Apps like Torque Pro (Android) or OBD Fusion (iOS) allow you to view live data, read codes, and clear the check engine light.
Owner’s Manual
Your 2013 VW CC owner’s manual contains useful information about the dashboard lights, fuse locations, and basic troubleshooting steps. Keep it handy during the process.
Basic Hand Tools (Optional)
In some cases, you may need a screwdriver or wrench to access the gas cap or battery terminals—though we’ll explain why disconnecting the battery isn’t recommended for resetting the light.
Step-by-Step Guide: How to Reset the Check Engine Light
Now that you understand the basics, let’s get into the actual process. We’ll start with the most effective method: using an OBD2 scanner.
Step 1: Locate the OBD2 Port
The OBD2 port on your 2013 VW CC is located under the dashboard, near the driver’s side footwell. It’s usually behind a small plastic cover. To access it, kneel down and look up under the steering column. You should see a 16-pin connector—that’s your OBD2 port.
Step 2: Plug in the OBD2 Scanner
Turn off the ignition, then plug your OBD2 scanner into the port. Make sure it’s securely connected. If you’re using a Bluetooth scanner, ensure it’s paired with your smartphone or tablet.
Step 3: Turn on the Ignition
Turn the key to the “ON” position (but don’t start the engine). This powers up the car’s electronics and allows the scanner to communicate with the engine control unit (ECU).
Step 4: Read the Trouble Codes
Follow the scanner’s instructions to read the stored trouble codes. Most scanners will display a list of codes like P0455 (large evaporative leak) or P0171 (system too lean). Write down these codes—they’ll help you understand what caused the light to come on.
Step 5: Fix the Underlying Issue
Before resetting the light, address the problem. For example:
– If the code points to a loose gas cap, tighten it or replace it.
– If it’s an O2 sensor, you may need to replace the sensor.
– For a MAF sensor issue, clean it with MAF cleaner or replace it.
Only proceed to the next step once the issue is resolved.
Step 6: Clear the Codes
On your scanner, look for an option like “Clear Codes,” “Erase DTCs,” or “Reset MIL.” Select it and confirm. The scanner will send a command to the ECU to delete the stored trouble codes and turn off the check engine light.
Step 7: Verify the Reset
Turn the ignition off, wait 10 seconds, then turn it back on. Check the dashboard—the check engine light should be off. If it’s still on, the problem may not be fully resolved, or there could be a pending code.
Alternative Methods (And Why They Often Fail)
You may have heard about “quick fixes” like disconnecting the battery or using a paperclip trick. While these methods work on older cars, they’re generally ineffective—and potentially risky—on a 2013 VW CC.
Disconnecting the Battery
Some people believe that disconnecting the negative battery terminal for 10–15 minutes will reset the ECU and clear the check engine light. While this can reset some systems, it won’t reliably clear OBD2 trouble codes on modern vehicles like the 2013 VW CC. The ECU stores codes in non-volatile memory, meaning they persist even when power is removed.
Additionally, disconnecting the battery can reset other systems—like your radio presets, clock, and adaptive transmission settings—which may require reconfiguration. In some cases, it can even trigger new warning lights or cause the car to enter a “limp mode.”
Using a Paperclip or Fuse Trick
There’s a myth that shorting two pins in the OBD2 port with a paperclip can reset the light. This is dangerous and can damage the ECU or other electronics. Never attempt this method—it’s not supported by Volkswagen and could void your warranty or cause costly repairs.
Driving to “Clear” the Light
Some drivers believe that driving the car for a few days will automatically reset the light. While the ECU does perform self-tests during driving cycles, it won’t clear active trouble codes unless the problem is fixed. If the issue persists, the light will remain on or come back after a short time.
Troubleshooting Common Issues
Even after following the steps above, you might run into problems. Here’s how to handle common issues:
The Light Comes Back On
If the check engine light returns shortly after resetting, the underlying problem hasn’t been fixed. Use your OBD2 scanner to read the new codes and diagnose the issue. It could be a recurring fault, a sensor that needs replacement, or an intermittent problem.
Scanner Won’t Connect
If your OBD2 scanner fails to communicate with the car, check the following:
– Is the ignition turned to “ON”?
– Is the scanner properly plugged in?
– Is the scanner compatible with Volkswagen vehicles?
– Is the OBD2 port damaged or dirty? Clean it gently with compressed air.
Pending Codes Appear
After a reset, your scanner may show “pending” codes. These are codes that the ECU has detected but hasn’t confirmed as active yet. Drive the car for a few days under normal conditions. If the problem doesn’t return, the pending codes may clear on their own. If they become active, further diagnosis is needed.
Multiple Warning Lights
If other warning lights (like ABS or traction control) come on after a reset, it could indicate a deeper electrical issue. In this case, it’s best to consult a professional mechanic or visit a Volkswagen service center.
Tips for Maintaining a Healthy 2013 VW CC
Preventing check engine light issues is easier than fixing them. Here are some proactive tips:
Regular Maintenance
Follow the maintenance schedule in your owner’s manual. Replace spark plugs, air filters, and fuel filters on time. Use high-quality fuel and oil to keep the engine running smoothly.
Check the Gas Cap
After every fill-up, make sure the gas cap is tight. A loose cap is one of the most common causes of the check engine light. If the cap is damaged or worn, replace it with a genuine VW part.
Use a Quality OBD2 Scanner
Invest in a reliable scanner that you can use regularly. Some scanners offer “health reports” that monitor your car’s systems and alert you to potential issues before they trigger the light.
Avoid Cheap Fuel and Additives
Low-quality fuel or excessive fuel additives can clog sensors and damage the fuel system. Stick to reputable gas stations and use additives sparingly.
Monitor Driving Habits
Aggressive driving, frequent short trips, and towing heavy loads can stress the engine and emissions system. Drive smoothly and allow the engine to warm up properly.
When to See a Mechanic
While many check engine light issues can be resolved at home, some problems require professional attention. Visit a certified Volkswagen technician if:
– The light is flashing (this indicates a severe misfire that can damage the catalytic converter).
– You’re unable to read or clear the codes with your scanner.
– The car is running rough, stalling, or losing power.
– You suspect a major component failure (e.g., catalytic converter, fuel pump, or timing belt).
A professional diagnostic can save you time and money by pinpointing the exact issue and preventing further damage.
Conclusion
