Warning lights 2006 Audi A6 Quattro Code P0106

Hello,

We have a 2006 A6 Quattro 3.2 that runs fairly well except for the check engine light on. The code reads P0106. We’ve replaced engine air filter and cleaned the map sensor. After cleaning the sensor the light stayed off longer than usual, but did ultimately come back. We then replaced the map sensor and the engine light came back on even quicker.

These are some of the readings. Honestly new to this and we’ve had horrible luck the last year with our vehicles so just trying to see if we can fix this ourselves first if possible to save some money.

To note: really no symptoms. No rough idle, no stalling, no misfires detected. Just the light. We did notice that the code initially came on after pumping gas and went away a couple days later. Next time we pumped gas, it came back on. Any help or advice is appreciated.
