308 1.6 HDI 3000 does not exceed

Hello, I have 2008 model 1.6 hdi 308 owner. In my vehicle, the engine protects itself from time to time and it does not exceed 3000 cycles, the problem disappears when the vehicle is stopped and restarted. When this does not turn on any malfunction lamp. Only the first time I start the car it says antipollution fault and goes out. We have connected the vehicle to the computer today P0409 EGR SOLENOID VALVE CIRCUIT, COMPONENT BLOCKED - P0490 DEFICIENT EGR - P2143 EGR VALVE ELECTRICAL FAILURE - P1351 Glow Plug Plugs - P1435 ADDITIONAL SYSTEM. Does the EGR Valve cause such a problem? Would it be enough to just clean it? EGR is very costly if it changes. I would be glad if you help. Thanks in advance.

First of all, welcome to us. Do the cleaning of the teacher, if there is no problem due to clogging, it will be corrected, probably causing many errors. new one is a little expensive vehicle 92 cm or 110 m teacher

My teacher of 110, I bought the car from my brother for 3 years. This antipollution fault was constantly writing for 3 years. The catalyst was discharged, I think it might be from this antipollution fault. But the problem of not exceeding 3 thousand cycles has just begun. He did it twice for 10 days. It gets better when I turn the vehicle off and back on. It does not light up any malfunction lamps. Normally there is no problem with the traction, I think I just started to burn 16 liters of fuel, which started burning 200 kilometers. Whatever I do, I will take my teacher to the authorized service or trust the master. Who knows from the pejo who understands in Mersin?

The reason why it does not exceed 3000 cycles is that the turbo cannot get vacuum because it is caused by the solenoid valve. but I advise you to change your glow plugs, they will have trouble in the future. Of course, some masters are not willing to disassemble it because there is a possibility of breaking. it boils when it does not change for a long time. The antipollution fault error is usually caused by short distance and unattended driving. It can be caused by both these errors and other reasons in increasing fuel consumption. If a good maintenance has not been done for a long time, I recommend you get it done.
