Turbo surge & VGT solenoid.....

Razorsedge · #1 (**permalink**) 12-03-2011, 05:21 PM

I recently installed an '03 turbo on my truck, it came with 2 vgt solenoids....the original 03 solenoid and a brand new solenoid. I figured I'd try the solenoid that was already in the turbo when it showed up, that was the original 03 solenoid. The turbo was surging when the truck was cold with that solenoid. The seller told me it was bad and included a new solenoid so no biggie. Well, I installed the brand new solenoid and.....same thing.

I figured I'd try my solenoid that was in my '05 turbo I removed before I took the turbo off again to clean it. Guess what? No surge! Smooth as ever.

What the heck? Why would I get turbo surge with a brand new OEM solenoid and no surge with my '05 solenoid with 60k on it?

just because a part is brand new does NOT mean its good. i can't tell you how many BRAND NEW ignition modules i installed that did NOT work back in my days of 5 liter mustangs. 3 in a row one day from my local ford dealer

I'm with busa dave. Just because it's brand new doesn't mean it will be functional. I had 3 brand new alternators that were junk, finally the 4th worked.

Use what works for ya man.

There is also a VGT relearn procedure that could be done.

I was under the impression that that did not apply to a 2005 model. Either way everything is fine now, I was just annoyed that a brand new solenoid would surge especially considering the cost of one.

Yeah, but with it being an 03 turbo and a solenoid for that turbo, maybe there is a difference.

relearn is based on the pcm, not the turbo.

To the OP-glad it's working!
