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.

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.
