Need advice with possible purchase

Remember that the codes are simply data points, just because they exist does not mean that each one means a faulty device.

It is only an event where the data recorded fell outside of the programmed parameters FOR THAT SOFTWARE VERSION. Many codes are simply programmed away by changing the parameters in the next update cycle for the module.

Sometimes they add up to a faulty part, sometimes they are bad software code and sometimes they can tell you more than you really need to know because the data was not designed specifically to be used as a buying tool.
