MONDECI intermittent heater witness

Hello, I have a problem with a Ford Mondeo 2.0 TDCI of the year 2002, the witness of the heaters is turned flicked, of Rebente loses power and the engine is covered, but if the contact is cut and I will scratch it again, hit it right now. The breakdown returns as soon as the accelerator was a little, that is, it is going well almost in relief.
An error code "High/low injection pressure" a thing like that.
The engine also heads to accelerate and a noise is heard as a lot of progress at this time.

hello. Tell me the DTC that you get pxxxx

Hello, does DTC mean the Averia code?
Are you Romanian? According to the name "Alexandru" ..........
