Can anyone help me? I have a Mk1 Octavia with a 1.8T AUM engine. I’ve been having a ‘P0172 System Too Rich Bank 1’ code pop up. i delete it and it only comes back months apart. thought nothing of it at first but popped up a few times recently. I’ve been down a rabbit hole on Google AI which has diagnosed my Air Mass sensor as needing replacement. It has come to this conclusion from me sharing the freeze frame data of the codes plus some live data that i got from the code reader at acceleration, 70mph and deceleration. I am aware to not fully trust what AI has told me so I thought i’d come on here to see if anyone has any ideas. Just gonna chuck in a few pics that show the data screen that has rpms, speed, long term fuel trim and MAF IMG_8168.heic IMG_8407.heic IMG_8404.heic IMG_8387.heic IMG_8397.heic
