If the wg stays closed with the line disconnected, but opens too early with the wg line connected to the n75 regardless of duty, the problem is pretty obvious.

Tested 3 working n75, no difference. Is wastegate actuator damaged? It's not tune problem, because .bin was tested in other cars and worked as intended.

Something is bleeding pressure to the wgs. if the wg actuator is damaged, i can't imagine it opening *more* easily than it should. the spring is either overcome with manifold pressure or it isn't.

N75s are normally open unless told otherwise, so if your plumbing is good, its either your harness or the ECU n75 solenoid driver.

problem seems to be solved, brand new n75 from bosch turned out to be f&cking crap and didn't work from the beginning. After a change for pierburg one everything works as it should.

I have never had a bad new n75, and i've probably used at least a dozen on various cars

There's aftermarket N75s being sold nowadays that plain and simple don't work. I've had this 2 weeks ago with an N75 ordered from Tecdoc or something stupid like that, and of course it wasn't an OEM one.

I have no logs because I have a boost gauge (makes things easier)
