Hello, in the 20th DTH, which becomes more or less, (from the Vectra DTI) it is not easy to cancel it, because the electrovalve that regulates it, seems to notice a lack of emptiness or something, the case is that I do not know why, it always gives failure to be disconnected the EGR cap, there they say some that are done by means of a modification of the switch Encuarrine the admission, manage to plug the collector's hole and use an old EGR Com nada mais do que o Vasto, sem o copo, mas para ver como as tapas de admissão sem ter o risco de engolir as válvulas e ..., essa já é a imaginação de cada uma
e avaliar. sorte
