407 Traction problem

My car is 2008 model 407 1.6 hdi executive black cd. It's been about 2 months since I bought my car. There was no problem with the pull when I bought it. During the feast, esp / asr system faulty followed by depollution system faulty. the cycle did not exceed 3000, but when I stopped and started the vehicle it passed the cycle 3000 until it gave an esp / asr error, but the depollution gave the system faulty failure when I ran it. I went to the service on the road to Sivasta, the turbo is problematic and they said it takes 4-5 hours. I went back to Kahramanmaraşa in that way until Erzincan. Kahramanmaraş stated that the service Egr should change, but we erased the mistakes in the brain and said, "If it repeats for a few days, then let us change." I had to go out and I got that shape, but I had a marked low traction in my vehicle. I was climbing 4-5 with the slope 2. The turbocharger of the vehicle was engaged in 1-2-3 gears, very high 4000, but I did not feel it. The return of Kocaeli gave the same error again. I took the vehicle to the master in the industry. As far as I can keep in mind, 3 of the heat injectors were broken, said the car changed, the car did not improve, the heat sensor did not change, the egr was deactivated, the air flow changed, the turbo air pressure sensor and ventilator, I think it changed, the mosaic filter did not change. The turbo was completely dismantled, the turbo master said there was no problem, the injectors were overhauled, these are the processes I can remember.

Thanks in advance for your comments

I had the same problem, the turbo was overhauled, it did not light up the lamp again, but there is also a whistle coming from my turbo

Get well, how simple is the correct answer actually, if you couldn't find it, you would struggle.
