intake manifold linkage problem???
The dealer says some type of linkage on my intake manifold may be failing and the fix is a new manifold.
Do any of you know what this might be? It's not spelled out on the work order.

I have no error codes but the dealer said I may have a problem down the road.
How common is it for the Swirl Flaps to get sucked into the engine and cause serious problems? Should I ignore this until I get codes or have running problems? Even though I am comfortable R&Ring the manifold myself I don't want the engine to fail while I own the vehicle and until after I take delivery of my Cybertruck, i.e. 500 mile range, 0-60 mph in 2.9", no paint on body to get damaged and, once Elon gets the window problem sorted out, the vehicle appears to be the ideal solution for this old man who cannot seem to keep from buggering up the corners of his Silver GL.

There is no need to do anything. These links break with German precision at about 120,000 due to repeated heating and age. the tumble flaps really do nothing. You might lose a tiny bit of bottom end torque with these being nonfunctional - this is just my butt dyno talking - but they have no effect on mileage, engine power or emissions.
if your check engine light is on as a result just rotate the whole pivot assembly fully clockwise to set the intake flaps in the fully open position. After three cold start driving cycles that light should go off on its own.
youll also have a stored code stating something g like “intake flaps stuck in actuated position”. I have two GLs, one with a broken link and one where they work - butt dyno says the functioning one has a crisper throttle tip-in but the differences are not enough to make me want to spend $2-3k at the dealer.
Your GL should then last you until 2027, when Cybertruck hits the streets.

Possibly the craptastic plastic used for the external linkage also connects to the flaps themselves, meaning that conceivably the flap could come off too.
It's sickening that no one is rebuilding these intake manifolds.

Don't worry about it now... Eventually it will break and you'll have something to worry about. When it breaks you can choose to do nothing as others have said, replace the actuator with aftermarket actuator kit made of metal, replace the entire manifold like I did, or replace the GL with your Cybertruck made out of indestructible intergalactic gems. You'll be OK with whichever approach you take...

this happened on mine and found this kit from uro parts was a good replacement. the actuator on the uro part has an aluminum arm instead of plastic, so it's a bit more durable. you'll just need to get some intake manifold gaskets when you pull the intake, swap out the actuator and pivot arm, and put the intake back on.

It took me about 10 hours to do this job. It didn't make sense to me to spend that much time to replace just that broken linkage knowing that another part down there on the manifold could break or go out as well. So I just replaced the entire manifold with a new one. I went through fcp euro for the lifetime warranty.
