I have c 220 Blutec w 205 2014. Yesterday it could not change gears until it reached 4000rpm, which happened after I tried to change to manual gears. Immediately I sent it to the service where I made oil+filter replacements, (engine + gear 2 days before) Which gave me the health report above. Made a removal of the trouble code and after that, we made a driving test which was perfectly fine. After 2 hours I went driving again and when accelerating it happened a shock/blocking which felt when the car accelerates to the maximum. After that, the gears repeat the same problem that cannot change gears until 4000rpm (at this stage the car loses the full acceleration). Today I sent it to another technician who made another computer diagnostic that resulted only in the "P033931 Position sensor 1 for the crankshaft has a sporadic malfunction". After removing the trouble code to make a driving test, the car did not give any problem at all, although I made 100 miles for the test, still testing today. Any idea what it might be?
