Pulls from 2500 rpm

Hello good, I have a problem in my Audi A4 1900 TDI 115CV, the fear is that when I go and step of 2500 rpm I start to pull, it also passes me and I climb the engine at 3000 rpm and from there it goes up only of revolutions, I have put the vag com and everything comes out normal, change the flow That it can be please tell me, I don't even know how to do. A greeting and thanks.

You have checked if your fuel is 95 .. if it is less octane as 84 it usually happens and the engine usually fails

Your bommba is the fault.

Look I know that it is something complicated but if you have already brought almost all the components that feed the Diessel begins to supervise the high pressure pump. Probably internally, the injectors are dirty or damaged. You can approach before carrying it to the firefighter who is the pump expert to see in what state your pump is. I hope at least helped in something ...

In the workshop they have also told me that of the diesel, so I am going to spend this deposit and I will make the expensive diesel to see how it goes, and I will look at something else, by the way with the theme of the bomb that you say, this car carries bombs bombs, I mean that the pump takes the injury. A greeting and thanks for the answers.
