How do you unplug that noisy air compressor sound under the hood when the engine is cold. ???????

 

Look down under the turbo on the intake side. You'll see a two wire plug. That's it. It should be right below where the tube connects to the turbo. Hope that helps.

 

its called the exhaust back pressure valve (EBPV). its solenoid is located on the turbo pedestal. to unhook it look at the intake side of the turbo just to the lower front of where the intake tubing goes into the drivers side of the turbo. there will be a two wire connector there bolted to the aluminum housing. Unplug it and never look back. Next time the turbo is out cut the actuator off and weld up the holes in the pedestal

 

There is a pic of the plug in my pics in my sig.
