Hello, My Seat Ibiza bj 2012 with 1.6 TDI had a mistake a few months ago with the injector cylinder 4 and I was advised by a close workshop to replace it. Since it was not quite cheap, I changed it myself with a suitable injector. With the launch crp129 evo device I then coded it with the new code of the injector. Now all cylinders run but it runs generally round with power drop and a lot of stinking exhaust gas. So the nozzle does not work like it What have I done wrong? I have often read that in addition to coding, a learning process is also necessary. How does it work with learning? Thank you and Vg
