Intake manifold fault
As some of you who have helped with another topic I posted here, my new to me e350 has some minor issues. I'm now getting an intake manifold fault code and have been told by a local Indy shop I need an entirely new intake. The cars barley worth what they want to do the job. Another post I read online says I can fix some sort of arm which is originally plastic from the factory but the replacement is metal.
Any advice here? Do I call it quits.

The best thing to do is to replace the whole assembly.... Fixing the outside lever does not do anything for all those plastic pieces inside the manifold that will also start coming apart. You can find them online for about 400-500.

What you get is always the OEM part from Pierburg (same plastic crap) - no reinforced aftermarket solutions available.

The proper way to fix it is to replace the manifold. There's actually some diy videos on youtube on how to do it. As others mentioned the Pierburg manifold is the OEM one and is about $610 from fcpeuro and that has a lifetime warranty. You could also buy various repair kits but that's a short term solution. The flaps inside the manifold will eventually break off and may cause engine damage as they will go into the engine when that happens. Still if you use the repair kit, it may be a couple years before that happens. When the intake runners aren't working right, the engine runs rough and gas mileage will probably suffer. Problems with air/fuel mixtures can also cook your cats.

Then you should inspect the car to see what part it needs. Just the lever is cheaper and can also be bought on eBay.

Before purchasing this metal lever (which also isn't cheap), I would check the inside of the manifold. If some of the flaps are already broken, save the money. In this situation you would cause even more damage if you make the system move again.
PS: I think the outside lever breaks BECAUSE there already is a problem inside (too much resistence that finally kills the flaps).

To get a view inside without taking off the manifold you will need some kind of endoscope camera - cheap at Amazon.

Many people have reported fixing it by just replacing the lever, a few have reported back that there was additional engine damage at some point when bits broke off a while later.
