The most common reasons a 2013 Volkswagen Routan has a check engine light are an emissions system component, a sensor, or a catalytic converter.
  • Emissions System: A faulty emissions system component, such as an oxygen sensor or EGR valve, can lead to increased emissions and trigger the check engine light.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2013 Volkswagen Routan has a check engine light?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

A faulty oxygen sensor is one of the most common causes of a check engine light. Symptoms may include a decrease in fuel mileage, hesitation or misfiring from the engine, rough idling or even stalling. A faulty sensor may cause the vehicle to fail an emissions test.

Any time there is an emissions fault the check engine light will be displayed. The purpose of the check engine light is to inform the driver that an emission related fault has been found, and that there are on-board diagnostic (OBD) trouble codes stored in the powertrain or engine control module. Additionally, since the emissions systems are so intertwined into engine control and transmission control systems, symptoms may include nearly any sort of drivability concerns. This may include harsh shifting, failure to shift, hesitation on acceleration, jerking, engine failure to start or run, loss of power, or any number of other drivability issues.

Due to the nature of electrical systems on modern vehicles, the range of problems these can cause are nearly limitless. However, there is a way to categorize them in two ways. Permanent and intermittent problems. Permanent problems appear and remain. This may be the vehicle will not start, the radio does not work, or the door chime will not turn off among many, many others. These problems are more straight-forward to diagnose since they present themselves at all time. This means there will always be a fault to find. Intermittent electrical problems, however, can be difficult or impossible to locate, since they appear then disappear without warning. The best case scenario for an intermittent issue is when replicating the problem is easily accomplished and understood. This allows a technician to make an issue semi-permanent, allowing them to find the fault. Other issues that come and go without warning and cannot be replicated on demand must occur when the technician is servicing the vehicle, otherwise there is no problem to correct. It is most important to understand that electrical system faults always require inspection, and can include the vehicle working in any manner, or not working at all.

Like we noted in the last section, general diagnosis symptoms are the most vague of the bunch. There are several diagnostic spectrums, electrical diagnosis, drivability diagnostics, engine diagnostics, transmission diagnostics, and the list could continue for about 5 or 10 more spectrums of diagnostics. The most important take-away here, is that general diagnostics are diagnostics that have no other spectrum in which they fit, or the problem is unknown. This means that any vehicle left outside of a repair facility with the keys and an authorization to perform diagnosis will be diagnosed under the general diagnosis spectrum.

When the Check Engine Light comes on, you may experience engine performance issues such as poor acceleration, rough idling, or an engine that won't start. In some cases, no abnormal symptoms will be experienced. Other systems like the transmission or ABS can cause the Check Engine Light to illuminate and lights for those systems can come on at the same time. Similar lights may say "Check Engine Soon", "Malfunction Indicator Light" or just "Check". In rare case the engine can overheat.

What are the initial diagnostic steps to take for a check engine light on a 2013 Volkswagen Routan?

When faced with a check engine light on your 2013 Volkswagen Routan, it's essential to approach the diagnosis methodically. Start by checking the gas cap; a loose or damaged cap is a common culprit that can easily trigger the light. Next, take a moment to review your dashboard gauges for any additional warning lights or unusual readings, as these can offer further insights into the problem. If the light persists, using an OBD-II scanner is a crucial step; this tool will provide you with specific error codes that can help narrow down the issue. Additionally, inspect the condition of your spark plugs, as worn or faulty plugs can also activate the check engine light. Lastly, examine the vacuum hoses for any signs of cracks, leaks, or loose connections, as these can contribute to engine performance issues. By following these initial diagnostic steps, you can effectively gather information to identify the cause of the check engine light and take appropriate action.

What are the common problems that could cause the check engine light to illuminate in a 2013 Volkswagen Routan?

When the check engine light appears on your 2013 Volkswagen Routan, it can be a source of concern, but understanding the common problems that may cause this warning can empower you to take action. One frequent culprit is a loose gas cap, which can lead to fuel vapors escaping and is easily rectified by ensuring the cap is tightened properly. Another common issue is a faulty oxygen sensor, which plays a critical role in monitoring exhaust emissions and can affect fuel efficiency if not functioning correctly. Additionally, problems with the catalytic converter can trigger the light, as this component is essential for reducing harmful emissions. A malfunctioning mass airflow sensor can also be a factor, as it regulates the air-fuel mixture necessary for optimal engine performance. Furthermore, issues with spark plugs or ignition coils can lead to performance degradation, making regular maintenance of these parts crucial. Lastly, the exhaust gas recirculation (EGR) system can present problems, such as a clogged valve, which may also illuminate the check engine light. If you encounter this warning, it is advisable to conduct a thorough inspection or consult a qualified mechanic to diagnose and address the underlying issue promptly, ensuring your Routan remains in peak operating condition.

What immediate actions should be taken for a 2013 Volkswagen Routan with a check engine light?

When your 2013 Volkswagen Routan's check engine light comes on, it's essential to respond promptly to prevent potential safety hazards and avoid expensive repairs. Begin by checking the gas cap, as a loose or damaged cap is a frequent cause of the warning light. Next, observe any other dashboard indicators that might offer further clues about the vehicle's condition. Using an OBD-II scanner to retrieve error codes can significantly aid in pinpointing the specific issue triggering the light. Additionally, if you experience any changes in the vehicle's performance, such as rough idling or unusual noises, these symptoms should be taken seriously, as they may signal more severe problems that could lead to significant damage if neglected. If the initial troubleshooting steps do not resolve the issue or if you feel uncertain about how to proceed, seeking advice from a qualified mechanic is a wise choice to ensure your vehicle's safety and reliability. Acting quickly not only helps in diagnosing the problem but also underscores the importance of timely intervention in maintaining your vehicle's overall health.
