I am posting this to help anyone else with a P0101 code, which would usually be a simple mass air flow replacement. I installed an aftermarket and an Audi factory new MAF $$$$. Still getting a P0101 code with a stumble feeling during acceleration. After lots of research and several different inspections I have finally found my suspected air leak. My passenger side intercooler hose had a vertical crack or blown out area that would close up when not under pressure hiding the defect. The P0101 code can mean a number of things, my advise check very carefully all air conections and hoses under pressure if possible
