Hello dear community, I bought a used seat Ibiza St 1.6 TDI 105 ps bj 2010 with 199999km, I have been driving since 5000km. I have a few problems with it. To the problems: When I start it it runs completely unevenly, i.e. the tachometer hops around between 500-800 rpm. When I have driven a few kilometers, off and start again this is gone, it still sounds slightly unround and jerks easily at the stand. When I drive to the intersection, it is in idle run no further than 1000 revolutions down and you hear also such a kind of electromagnetic noise, when I stand then it goes down to 600 revolutions and the noise is gone. Vllt can help me further who has had such problems before. I’m really desperate and would love to light the car if I wasn’t dependent on it.
