The OBD-II trouble code P2184 indicates that the ECM detects an issue with the car’s coolant temperature sensors. Volkswagen vehicles are known for their dependability, but the coolant temperature sensors commonly need replacing after extended wear. It is best to have a reputable auto repair shop that specializes in imported or VW vehicles diagnose and analyze the issue if changing the spark plugs does not get rid of the OBD-II code after a couple of driving cycles. These include worn-out ignition wires, low fuel pressure, or a defective mass airflow sensor. Most likely, this is because of worn-out spark plugs, but other problems can trigger code P0303. The OBD-II trouble code P0303 indicates a misfire in the #3 cylinder in Volkswagen cars. If this maintenance is not taken care of on time, the check engine light will come on after 120,000 miles. Most VW vehicles need to have their spark plugs changed around the 90,000-mile mark. While frayed wiring or corrosion is the most likely cause of a problem with a Volkswagen’s oxygen sensor, the ECM may be malfunctioning as well. If the check engine light is on, the car stalls frequently, or excessive amounts of smoke come from the exhaust, the oxygen sensor may be malfunctioning or failing. OBD-II trouble code P0130 is a result of the Engine Control Module (ECM) failing to detect any activity from the oxygen sensor. Oxygen sensor failures are not a problem unique to VW vehicles it’s common for an oxygen sensor to fail between 80,000 and 100,000 miles.
If the car’s check engine light is flashing and the engine is shaking, at least one of the ignition coils may need replacing. Sometimes a brand new ignition coil will fail before 10,000 miles. Many Volkswagen four-cylinder engines, most often the 1.8T and 2.0T, have issues with their ignition coils. These include trouble codes P0300, P0301, and P0302. Many trouble codes can indicate a problem with the car’s ignition coils. Ignition Coil MalfunctionsĪnother typical OBD-II code readout for Volkswagen vehicles indicates an issue with either the car’s ignition coils.
If replacing the gas cap does not reset the check engine light after a few driving cycles, the EVAP system needs to be inspected by a trained Volkswagen technician. Sometimes the cap needs to be tightened, but it also may need to be replaced entirely.

The gas cap’s seal can degrade or crack after continued use which can result in an improper fuel tank seal. Often, this problem because of a loose or malfunctioning gas cap. The OBD-II trouble code P0457 is an indication of a problem with the vehicle’s EVAP system. In fact, the most common diagnostic code for Volkswagen vehicles is caused by a loose gas cap. The check engine light is not always a sign of doom for a beloved VW. While OBD-II codes can be useful, it’s important to remember that a trained diagnostic technician should investigate and analyze the problem because multiple issues can cause OBD-II trouble codes.
However, the readout of the OBD-II trouble code is only the beginning of diagnosing and fixing a problem with a Volkswagen vehicle.

Most auto part stores can perform a free plug-in diagnosis with an OBD scanner. While some vehicles can display the OBD-II trouble code on the dashboard, many older VW cars don’t have that capability. When a Volkswagen’s check engine light turns on, it means that the vehicle has at least one On-Board Diagnostics (OBD-II) trouble code.
However, for Volkswagen owners, the check engine light (or the Malfunction Indicator Light) can cause even more anxiety due to the difficulty of finding a reputable auto repair shop that specializes in repairing and maintaining imported vehicles. The car seems to be running fine until that orange engine in the middle of the dash suddenly lights up. Nearly every car owner can understand the stress that accompanies the check engine light.
