I have a problem with my 335d 2011, when the engine is cold the car revs itself and smokes a lot of blue smoke plus the injectors values are really high and chaotic(from 0.3-0.4 values to 1.6), when the engine is hot they dial down to normal values and the car runs fine pulls fine and there's no smoke at the exhaust pipes(turbos were rebuild 300 km ago)(when the car gets to operating temperature all is good), there were no error codes for months but today it hit me with the ''3F40 common rail sensor Offset-Tester'', what could be the issue ? The fuel filter hasn't been changed in like 30.000-40.000 km.
