Hello! have recently 2 new TGX,Sattelzugmaschine,Fahrerhaus XLX approx.25000km(ca2months) EURO5 with No X sensor! one drives North —- South! the other rather in the flatland! and they consume me too much!I did not have that with my other TGA! yes it always means the engine has to start and so on. but then 5 to 6 liters more! Flatland TGX: 33L on 100/km North-South TGX: 35-36L on 100/km Flatland TGA: 27-28L on 100/km
