What's the Audi fault code p308d00?

If Your Audi has a check engine light come on at the dash I recommend that You use an OBD II scan tool to try to find the source of the problem. All vehicles made after 1996 come standard with an OBD II port that allows You to read codes stored by the ECU. If You have a code P308D00 when You scan the ECU that usually is a sign that there is a problem with the fuel pump. You may notice that Your car sputters or stalls while driving and does not have adequate fuel pressure at the fuELRails in some cases. This is usually a sign that You may need to replace either the fuel filter or the fuel pump depending on the model.
