14 is Ignition signal, I don't know about this one and doesn't seem like a problem to me so I think I will clear it and see if it comes back.

42 is Speed Sensor, I'm pretty sure the speed sensor is on its way out just due to how its been acting and from what I hear is a common thing to go bad.

I just got to figure out a way to keep the check engine cluster from losing electrical connection.

Regarding the speed sensor signal, it's possible the problem is with the oem odometer cluster. Note these instructions are for the USDM-spec Mkiv-TT:

• Remove the dash trim that houses the Odometer, on the odometer harness find the pink wire and cut it then splice the pink wire with the blue and red VSS input wire.
• First try resolder the cold solder points on the board.
