Повтарящ се проблем с ускорението

[martinio Профил]

Здравейте,
колата е 330 д 204 кс дизел 2003
на няколко пъти вече ми се случва, да натисна газта докрай (тоест да ритна кикдауна) и вместо "да ме удари бързият влак отзад" както се изразява един приятел, колата просто не ускорява, като пусна газта държи високи обороти и светва check engine лампата. След това като мине малко време се нормализира и си върви нормално. Аз си проверявам грешката с INPA и я чистих 2 или 3 пъти но тя продължава да го прави , аз мислех че е от нафтата отначало и смених Лукойл с Еко , но вчера пак се случи същото. Грешката която дава е:

Някой ако има идея какво е ще съм благодарен.

Exhaust Gas Recirculation Flow (EGR) Excessive Detected
What does that mean?
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor (DPF). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0402 code means that OBD detected an excessive amount of EGR. Symptoms You may notice drivability problems such as the engine may surge off idle. There may also be other symptoms.
Causes
A code P0402 most likely means one or more of the following has happened:
The DPFE (differential pressure) sensor is faulty and needs to be replaced
There is a blockage in the EGR (most likely carbon buildup)
The EGR valve is faulty
The EGR valve may not be opening due to a lack of vaccuum
Possible Solutions
With a P0402, it is common for people to replace the EGR valve, only to have the problem return.
The most likely solution is to replace the DPFE sensor.
Check the voltage at the DPFE sensor both at idle and when the EGR is open Replace the DPFE sensor
