2009 Volkswagen Passat CC Highline 2.0L Misfire, MIL Lamp on
Well I'll call it a fix. Customer declined repair but smoke was pouring out from the rear main. Crazy as it sounds the lean condition was slowing the engine speed just enough to lower the high pressure system and set that pressure code. Don't be fooled. Trouble codes: 04506 (Fuel Pressure sensor Intermitent), 00369 (Lean Bank 1), 00768 (Random Misfire), 00772 (misfire 4), 00770 (Misfire 2).
