If you own a Volkswagen, you want to be on the lookout for specific issues and failures aside from general wear and tear. When you are aware of the issues that could crop up, you can quickly get your vehicle to a professional who can diagnose and repair the problem. Here are five of the most common VW engine issues.
1. Check Engine Light
This is a very common problem, usually due to the wrong sensor or a software problem. This is a general warning light that tends to pop up more than other, more specific lights, so it can be confusing for you to determine what the issue is. First, if the check engine light is yellow, this indicates a warning rather than an emergency.
Did the light come on while you were driving? Turn off the radio so you can better listen to what’s going on. Here are some common culprits for the check engine light:
- Gas Cap: A loose or damaged gas cap can trigger this light, so tighten it up.
- Faulty Oxygen Sensor: This can be triggered by an emissions issue, another common culprit. The sensor could be faulty or just clogged with dirt. In any case, it will send out an incorrect reading, triggering the check engine light.
- Catalytic Converter: This device converts carbon monoxide into carbon dioxide, and a faulty converter leads to pollution, while at the same time reducing performance and fuel economy. Get it checked out immediately.
- Worn Spark Plugs: These fire up your gasoline engines. They don’t need changing very often but you should get them checked to avoid misfiring.
- Engine Overheating: This is considered an emergency, as an overheating engine can quickly catch on fire. Pull over and check the thermostat. If it’s very hot, pop the hood and call a mechanic.
2. Oil Sludge
Another common issue is when oil sludge builds up, which tends to happen between 70,000 and 90,000 miles. You can prevent this when you follow all manufacturer guidelines on oil changes and the kind of oil used in your car. Make sure you get regular oil changes!
3. Wiring Harness Shorts
These are problems that seem to happen more with Jettas, usually after hitting about 100,000 miles. Always have electrical problems checked out by a qualified repair shop.
4. Airbag Malfunction Light
This is a major safety issue and needs to be addressed. This problem also tends to happen as you approach 100,000 miles. If you see this light come on, take it to a repair shop to get the airbag checked. A malfunctioning airbag is a serious safety threat. Also, you could be fined if pulled over and the police officer notices this light illuminated.
5. Coil Failure
Passats in particular have issues with coil failures, which occur around the 75,000-mile mark. Call your qualified European car repair shop, as they typically keep these coils on hand to address this common issue.
