I had the same problem as you described. Turned out to be water sitting in the banjo hose between airbox and AMM and a disturbed air inlet to the inlet filter housing, allowing water into the air filter box when driving through rain. What's your filter element like?
Another source of troubles (especially at nearly 500k, like mine) are old sensors with bigger fluctuations in their signals as they get old. Worth checking especially if they're in since the car was new. This sometimes throws up error codes but not always.
Hope this helps. Best of luck.
