Unpluggedthe battery and plugged back in - still misfiring and same codes came up. Maybe something got fried when that wire disconnected, not sure. Symptoms: Smokes from the exhaust and smells like death. Starts and runs shaky. Low power under around 2500rpm until the turbo kicks in. Mabysomebody here has experiaced something similar.My 2011 B8 2.0 TFSI 211 developed strange misfire / fuel cut under 2000 rpm when engine is cold. Mine is having the same exact problem after I had the K04 stage 2 turbo upgrade for B8.5. Sent APR an email of my problem and still waiting for a response. 2013 audi a4 b8.5 Edtr1oi.
