Hey
I am new to TDI world, I've got 2004 Passat my engine seems to be running rich. It's winter but fuel economy is poor, can smell unburned fuel after engine warmed up, on acceleration there is a smoke behind me. Also on start up there is puff of blue-ish smoke but doesn't look like and oil. I've cleaned EGR, inlet manifold and done full service as well as new fuel filter and thermostat with coolant change. Fuel efficient is 40mpg mixed driving best 50 motorway (imperial units) any ideas?
Thank you
