It took me a while, but I finally found the time and figured out how to fully take advantage of and utilize ISTA to properly diagnose the issue to resolve this.
Pre cleaning - live ISTA sensor feeds showed intake pressure sensor deviating by +/-2.2 hPa
Post cleaning - live ISTA sensor feed shows identical readings from all 3 pressure sensors: intake (manifold) pressure sensor, ambient pressure sensor, charging (boost) pressure sensor.
Take away: routine pressure sensor cleanings may help

Hi, I have the 101F01 code and was wondering how you measured the readings from the three sensors to confirm they were dirty? I have ISTA working on mt laptop but am not familiar with it. Can you provide some info on what pages in ISTA you selected to check the values? Thanks.
