How To Diagnose A Bad L5P Turbo Actuator! (Surprisingly Common Issue) 

So few of us have tuned 2020+ trucks and most are stock turbo. Thanks for the info, I'm looking at an aftermarket turbo,injectors and possibly cam. Trying to make the big boy power lever. I've had the injector pigtail issues twice now and driver side sucks passenger side is easy.

Happened to mine and I relearned the actuator with snapon scanner and has been good for probably 30k miles/1 year. Did not replace the actuator

My 2017 new stealth l5p keeps pulling code for actuator as well. It's got alot of mods to exhaust. I can clear the code and then comes back up. It had brand new actuator they wouldn't even work.

I know this is an older video, but what are the codes that come up when this happens? I have P0046 U18A2 U0076 and I’m not sure if it’s an actuator or a can bus issue

Where can I purchase a a actuator

Have you thought about switching to a Wehrli S467 set up or similar and ditching the actuator all together? I think you rode in one with a 472- what were your thoughts on it? I love Matt’s set up and under hood looks spot on.

Had a tuned and deleted 20 with the exact same thing happened. Month later still waiting on turbo😂

What constitutes "higher mileage"? My stock 2018 with 88k is getting codes: P0046 Turbo Boost Control Solenoid U010C Lost Communication with Turbo Dash message of "174 miles to speed limited to 65mph" but then it goes right into limp mode less than 5 miles later. Local shop didn't get it to appear after I cleared codes but guess that it's VGT actuator and they say it's possible the DPF pump and heater are bad too.

How much is the acuater

Would a bad actuator make it have a sqeak while using the exhaust brake? Or is it the turbo going out and that throwing the actuator code?
