Here’s a good article on how to diagnose whether your fuel injectors are bad from procarmechanics. If the fuel can’t atomize properly, the engine will misfire.

Injector Issues: A bad fuel injector(s) can cause a misfire.

Fuel Mixture: If the engine is running rich or lean, the engine will misfire and throw the fuel mixture related codes, such as P0171, P0172, etc.

Alternatively, there may not be enough fuel for proper combustion, or the fuel isn’t atomizing properly. Keeping in mind that any engine needs air, fuel, and spark for ignition, your Volkswagen CC’s fuel system can often cause the engine to misfire. There are other misfire related codes as well, but those are the most common ones.

There can be other reasons this code is thrown, you can see more by clicking on the P0301 link above. Although it’s a bad sign when the service engine soon light flashes, when one of these codes comes up with it (and nothing else), it’s almost always one spark plug or ignition coil.

P0301-P0312: Cylinder Specific Misfire- These trouble codes correspond with a specific cylinder misfiring (cylinder number corresponds with its place in the firing order).

That is unless all the cylinders share a common coil (distributor ignition). This code is often thrown when there is a fuel issue, or a timing issue, and not just bad ignition components. It means that the engine has a misfire, but the computer can’t detect which cylinder that it’s coming from.

P0300: Random Multiple Misfire– This is one of the most common codes that is thrown when the engine is misfiring.

These parts work in concert to ignite the fuel in the combustion chamber at just the right time. The ignition system consists of spark plugs, plug wires, and the ignition coil packs (older vehicles have a distributer that has the same function as coil packs). The ignition system is the most common reason that the check engine light will flash. Use it to find out exactly why your vehicles computer decided to flash this light.ĬC Check Engine Light Flashing Due to Ignition Issues Here are the most common issues that end up causing the check engine light to flash. These trouble codes will be able to tell you where to start hunting down the problem.

There will always be trouble codes associated with the check engine light blinking. It’s flashing to let you know that if you keep driving the vehicle, you are going to ruin the catalytic converter and/or damage the engine in a meaningful way.īlinking Check Engine Light Diagnosis: Volkswagen CC There can be other situations that can cause the check engine light to blink as well. This raw fuel can detonate, which causes damage to the catalytic converter and the exhaust system itself. When your engine is misfiring, it is dumping raw fuel into the exhaust. This flashing light should not be ignored. Most of the time, that serious problem is a misfire. This continued for a few miles and then when the block was completely warmed up everything felt and sounded normal again.A flashing check engine light is your Volkswagen CC’s way of saying “I have a serious problem, don’t ignore me”. The engine didn't have the usual throaty sound but very brittle sound. I could hear what sounded like the throttle opening and closing. Like I said, I had to leave, and as soon as that light went away I started pulling away and driving.Ĭar felt.very metallic. Almost like the car is idling too low and the car is shaking but it was still above 1000rpm.Įngine light started flashing and continued to flash for a little but went away. I was in a rush later this afternoon and hopped in the car, cranked it up and I immediately felt some shuttering that lasted ~6 seconds at best. It also rained for about 2 days after the snow storm. Today was around 45 and the air was quite saturated. It snowed and temperatures have been up and down like crazy these past few days. I last drove my car on Friday morning and left it parked in the parking deck away from the elements.

Tried looking for this but couldn't really find anything that pertained to this:
