Renault Traffic does not accelerate

Hello everyone, my name is Oscar and I am new in this. The fact is that I have a Renault Traffic, 2.5 dci 140, two weeks ago we changed the turbo, and in principle everything is fine, but a week later, the auxiliary strap was broken, Varrata Fairy, the case is that the van starts, it stays 1200 laps of rebellations, and the preheating witness on, but does not accelerate. The mechanic has gone crazy with her, and does not know what happens to her, in the end, I have taken it and I will take a look, someone has had that problem or know what happens to her? Thanks for everything.

Hello, I am Alex problem is that the cche of yours has a memorized DTC or rather a failure, tens to remove and try it again

When you know how to fail it and help you

Hello everyone, regarding the Renault failure, I tell you a little. I have taken her to Renault's workshop, and I think they have buelto crazy with her. I have been told that to start all the engine electric cables, because they have been stained with oil, and therefore they have communicated, and that then, it would be seen what is broken. That is, I have to spend between € 2000 and 3000, to know, it has broken, and if I repair it. What do you think. Chinese sounds like it.
It is normal that you have to change all the motor cables to know what happens to you. Anyway, for the moment, they have charged me € 165, to tell me, that they do not know what happens to him, and that if I spend another 2000 approx, they will know better that it happens. I don't know what to do anymore. An oil leak, can all cables be annoyed? . With 140km, it is worth repairing it, because they tell me that although the distribution strap changes it 200,000km, if it has been stained with oil, they have to change it, another € 500. Greetings and thanks for everything
