A full scan with the Schwaben Scan Tool should tell you if anything else is happening that shouldn’t be. If your misfire does not follow either the spark plug or the coil pack when you switch them to another cylinder, you might have other issues. Black, burnt, buildup signifies carbon and means you likely need a good old fashioned walnut shell blasting, which we offer as a kit with the proper adapter to use with your engine. You can usually look at a plug and tell if it is fouled or dead. If the misfire persists in the first cylinder, you should then try switching the spark plug to CYL2 and check once more. First, switch the coil pack from CYL1 to CYL2 and see if the misfire code reads P0302. This could be one of several reasons we listed above.

If you have P0301, your first cylinder is not firing. To confirm, you should first determine what the cause of the misfire is. With the VW Schwaben Scan Tool, you will be able to see the codes, which will read P0301, 2, 3, or 4, depending on which cylinder has the misfire. If the CEL is constant, it registered a code once or randomly and is alerting you that you have a random misfire. Blinking means the misfire is happening on every cycle, which means you effectively have a non-firing cylinder. If your CEL is blinking, DO NOT DRIVE your car. If it happens while driving at temperature, it is probably either a bad coil, bad plug, or both.įirst, you will see either a blinking or constant check engine light. If your engine experiences misfires on a cold start, it is likely the cause of carbon buildup, meaning you need to walnut blast your intake valves. It can happen either when driving or on a cold start, which signifies two different problems. MK6 GTI coil packs are notorious culprits, as are the spark plugs themselves. So, it’s important to address your MK6 GTI ignition service needs immediately rather than wait for a more expensive repair down the road and possibly not legally receiving your annual registration.Ī misfire can happen if the spark plug has fouled, the coil pack is bad, there is excessive carbon buildup on the valves, or the air/fuel mixture is wrong to the point that it will not ignite. Not only will a misfire ultimately foul your catalytic converter, but it will cause you to fail vehicle inspections and can ultimately become more than inconvenient. In the MK6 2.0T TSI, this is a common issue at higher mileage, especially if your engine is making more power than stock. The air and fuel in the combustion chamber were not ignited due to a lack of spark, so it ‘misfired.’ This is less than ideal and can be the result of one or more faults. Misfires happen when a cylinder does not receive spark for one reason or another and the cylinder does not ‘fire,’ or rather, combust. Today, we’re talking about the MK6 2.0T TSI misfire problems and how you can fix them with a little help finding the right GTI parts to get the job done. Most common issues are well documented and should be addressed if you plan to pick one up or have just added one to your stable. The MK6 is still an incredible platform and is more affordable than ever, but they’re becoming older and will need some maintenance.

It took what the MK5 did well and made significant improvements to the car at every corner. The Volkswagen MK6 GTI 2.0T TSI took the MK5 and made it more appealing.
