immobilizer light is ok
car starting no problem
but when reach 3000 rpm car shut down suddently

check the camshaft sensor

EGR,camshaft sensor and more,but is inposible to be 100% shure only the data from scnaer is not enough,and in your case the data that you read from ECU is not acurate .
This is like emergensy mode,or the ECU is stoping the motor to prevent damage.It is posible that the presure is to high .I thing the engine is dCi?

You can be the problem of wiring. Behind the battery is a metal casing over ECU. It usually causes problems

You need a scaner for that engine able to read data live.I think the problem is on rail pressure too much pressure at 3000rpm.

i scan car with clip showing engine speed sensor
also very much black smopke from exhaust pipe.
i changes pressure pump & common rail but useless nothing change
may be wiring fault or crank sensor fault
but not sure
thanks for reply to all dk members

EGR,See with Ossciloscope the signals from speed sensor too.
