Passat TDI 110 CV Power Loss

Sorry for not answering before, but I have not had time to "put her hand in the car." Following the good advice, the EGR valve and the admission collector did not have too much dirt but at the time I stopped losing power, I also discovered a damn of the Turbo (intercooler output) that I have also changed.
Thank you very much for your help, the car with 330,000 km is luxurious.

Thank you very much, clean the EGR and the admission collector, probe and the power losses had disappeared but listened to the blow, review and change an intercooler output sleeve. The car goes like silk with 330,000 km.
I repeat thank you very much.

Such, I had that same problem for a long time on an A3 TDI 110 hp and that is that on the highway or already starting from 120 or 130 km/h. Speed ​​(in city everything was correct and the car was won, the car was suddenly without strength and I had to give the contact key back and forward so that it would catch up normal strength and so several times, although in the end I stopped doing it, taking more or less time in it.
It turns out that the problem was according to each other: bad flow, egr badly, escape into some sleeve and erroneous signal, ... all wrong. It was completely solved by putting the car in a workshop with a good diagnostic machine and saw, as Betis above says, that the problem was the dirt accumulated in the turbo (variable geometry) that prevented its correct operation, caused overpressure in the same Emergence to the switchboard that was responsible for cutting = lack of power. That is why, when removing and contacting the system was reset and everything went well.
Solution: Disassemble and clean the turbo and surrounding and pay 400 eurazos to the specialized workshop; Of course, now you go 100% and never more problems.
