Hi,
my car (see sig) is over boosting as per 011 block VCDS logs I took. I'm seeing up to 2600 mbar, which is about 30.5 psi gauge. Max should be 24 psig to go with my VNT-17, which is 6 months old.
I want to test if the turbo actuator is getting enough vacuum to do it's job. As per a posting from Canadian Grizzly, I got someone to cycle the ignition while I crawled under the car and observed the actuator rod. It didn't move. I *think* this means I have a vacuum leak, or a bad N75 solenoid valve.
So much of the advice in these forums is non-BEW (PD) engines, I worry that the advice is not pertinent to me. Could someone please confirm that the turbo actuator rod *should* move when the ignition is cycled?
thanks!
