I went to the dealer and they said I needed valve gasket clip tube, and remove all crankcase pressure regulator valve and turbo inlet pipe. They also found code for misfire and fuel with EVAP performed TBS. My car later stop running while I was driving. My car is turning over but will not start. I am getting a code P0864. What is the first thing I should do after I get a code P0864 TCM Communication Circuit Range/Performance on my 2007 vw pasast to get my car at least starting?
