I just came across a google link that there are additives for cleaning your vanes on the turbo. Is this snake oil Or does it really work? I know some folks are up in the air about adding additives to their fuel tank to clean out injectors and what not.
i also read that it’s a very good idea to always keep your engine break turned on so it does not build up a lot of carbon on the vanes?
I’ve had my diesel for over five years and never knew about these two situations 🤨
Never heard of any additive that would clean the soot off the turbo actuator sleeve.
But, the second point is a big YES!
Run the exhaust brake as much as you can, the exhaust brake uses the variable turbo actuator sleeve to close off the turbo to cause the exhaust braking effect.
So, running the exhaust brake makes the sleeve run through its full travel, helping to keep the soot from building up on it and blocking it.

now all these ads are popping up since I started reading about it 🤦♂️
How would anything in an aerosol can do anything for an internal turbo issue?
You'd have to disassemble (at least partially) the turbo exhaust pipe and spray it inside I would guess. Still not sure it would do much.
To OP, the biggest things you can do to prevent soot build up in the turbo is use the engine brake (even the auto setting) and RUN THAT THING. Heat burns off soot, believe it or not.

Who said anything about an internal issue? The OP says he wanted to CLEAN the turbo vanes, and that's exactly what the CRC cleaner does. Instructions clearly state just run the engine and spray it in, avoiding getting it onto the MAF sensor which may require removing the air filter temporarily.

what’s the auto setting? I just have a button on the console I have to push every time I start the enging to turn the brake on/off.

The variable vane mechanism is INSIDE the turbo on the exhaust side of it, thus an internal issue.
My 24 uses the exhaust brake all the time without me pressing any buttons. Unlike the 2019, I can hear and feel it. If a fuel additive is claimed to reduce soot, thats what you would use to keep soot down in the turbo. The intake vanes should be clean unless there is too much oil being drawn out of the ccv. It will take a lot more than spraying into the intake if thats the case.

If soot is getting on it, then air is getting on it. And if air is getting on it, then a cleaning product like CRC would get on it when sprayed in. I still don't follow. OP asked about cleaning the vanes in his turbo, correct?

You going to pull the pipes off the back of the turbo to clean it? OP does need to clarify his question so we aren't ASSuming. Washing down the vanes, simple, remove the intake and spray away, provided his definition of vanes are the ones sucking in air and compressing it.

Only way this can be is if you've used Forscan to permanently enable the exhaust brake. Mine will stay on if I am only out of it for a short period of time (less than half an hour), otherwise it defaults to off and I have to press the button twice for automatic exhaust braking.
