What's the 00054 vw code?

If You get a check engine light in Your Volkswagen while You are driving the first thing that You should do is get off the road as soon as possible to prevent more damage to Your engine. Once You are stopped You can use an OBD II scan tool to read the codes in the ECU. If You have a code P00054 when You read the ECU that usually means that there is a problem with the oxygen sensor on bank 1 after the catalytic converter. Usually this happens when the sensor or catalytic converter is failing. I recommend checking the sensor to make sure that it is working and free from debris and replace it if necessary.
