What's the 01317 vw fault code?

The 01317 fault code in VW vehicles indicates an issue with the control module in the instrument cluster. This can mean a few things. The wire to the cluster could be bad, or the ground could have shorted. In either case what it means is that the computer in the car can not talk to the instrument cluster, and therefore cannot update the system for information. In some cases, this will only affect what information You can access, while in others the car will also not be able to parse data. In any event, You will need to take this in and have it looked at, as one of the first things You will lose will be the speedometer, which iAm sure You agree is important.
