#AUDI A4 DEFAULT CODE 005660 GLOWPLUG FOR CYLINDER 3 HOW TO#
Here’s a good video on how to diagnose an injector, it can be a little tricky. Bad Fuel Injector– If you have a fuel injector that has gone bad, it won’t be able to properly atomize the fuel and you’ll get the P0303.Coil Packs– Coil packs rarely go bad, but when they do, they can certainly cause P0303 in your Audi A4.Here’s how to tell if your plug wires are bad (video). Spark Plug Wires– On most modern engines, the plug wires are not nearly as long as they once were, but they can still go bad.Here’s a great video on how to see if a spark plug is bad. That being said, the plugs are a great place to start. Most vehicles now come with iridium plugs that need changed very infrequently. Take a look at the electrodes and see if they are in good shape. Bad Spark Plugs– Spark plugs are one of the most common causes of P0303.They are presented somewhat in order from most to least likely to be causing the code: Here are the most common problems that will throw the code. There are quite a few things that can cause the P0303 trouble code to trigger the Audi A4. You may smell raw gas coming from the tailpipe.Fuel mileage will suffer (often not drastically).The vehicle may produce excess vibration, especially at lower RPM.It depends on how serious the misfire is, and how many cylinders the engine has. The vehicle itself may begin to run rough.The P0303 trouble code will trigger the A4’s service engine soon light.An important thing to understand when finding the location of cylinder 3 is that it’s going to be the 3’rd cylinder in the firing order of the vehicle, and not the 3’rd cylinder that you might see when looking at the engine. P0303 is a cylinder specific misfire code, which means that Cylinder 3 is misfiring and causing the code. Mileage may suffer as well when your A4 has P0303. The engine is also not firing all of the fuel, so raw fuel is also passing through cylinder 3 into the exhaust. Driving with a misfire can damage the vehicle’s catalytic converter. Unlike a lot of the OBDII codes, this code has to do directly with engine combustion. These particular codes indicate that there is a misfire in one of the other cylinder’s as well.įixing P0303 should be considered a high priority. It will often be accompanied by codes P0301, P0302, etc…. The nice thing about P0303 is that it’s a cylinder specific trouble code, which makes diagnosing the problems simpler than P0300, which means that the cylinders are randomly misfiring. P0303 should not be ignored, and can be a threat to the drivability the Audi A4. P0303 is a relatively common Audi A4 trouble code.
