I have messure the n75 with a multimeter and i ve seen restinance between to pins 14 ohms and volts in plug 8,9.

It sounds like the garage has decided to use you instead of a cash machine....

 

However, I suggest the actuator may be at fault, that garage will tell you you need a whole new turbo but actuators are available separately, they may tell you you need a new MAP sensor, again, highly unlikely.

Carage took my ass and slaped it like a bitch...

I forgot to mension that actuator is also new due to cash machine you mentioned🫣

Also we have done a vaccum test and it was ok.

Dont know wat to think.

Someone told me about the egr,but the faults only idicate pressure problems..

Any other opinion at this point will be very helpfull boys.

Is there any test to do in exhaust?

Please..
