I am trying to diagnose a problem, that suddenly occurred with my dci 2.0 Nissan Qashqai +2.
During acceleration, I heard a strange noise, after which the motor started sounding completely differently, much louder especially during acceleration in lower gear, lower power and with unstable speed. Check engine light is on (yellow) and after stopping the car it won't turn on any more, I can crank it, but it won't start.
I topped up on engine oil, but this didn't help.
From what I gathered, this is most likely the spark plugs or the fuel injection system. Since the car was able to drive home after the incident and can not be started at all after, is this an indication, that it is the spark plugs? After all the spark plugs are mainly needed when you start the car? On the other hand, why would the spark plugs be causing the other symptoms? What else could be going on? I didn't see any fluid leaking under the car.
