Scotty do you or others here have some sort of experience with diesel Volkswagens?
Problem is Passat 2012 TDI shows swirl flap intake code randomly.
Code has not come back since but it triggers once in maybe 2 weeks or so.
140xxx miles, automatic transmission.

The answer: Yes, Some.
This is not a question:
"Problem is Passat 2012 TDI shows swirl flap intake code randomly."
What code? There are quite a few codes it can set on the subject of intake flaps (/what ever they have)
But generally as far as I remember it's an EA189, chances are you just need to take off the manifold and clean everything - used to be a common issue on these 2.0 TDIs.
Also what's the real world MPG on it? I remember the Passat 2.0L and being inefficient (under 40 mpg), getting worse gas millage than a Camry petrol...
Passat's been driven highways only, gets 37 mpg. The exact code cannot be traced because it doesn't show most of the time. Took it to a specialist and he said there's an engine problem.
That's unfortunate, what I would do is removing the flaps from the intake and seeing their condition (and see the actuator has free movement). I know that severe buildup was an issue on early EA189 engines and it supposedly already solved on the 2012 model year.
It can also be an electrical connection, the actuator, plenty of things - so another possibility is to just wait until the code stays there in a more permanent manner.
Well, those flaps often do get stuck or their actuators go bad. The only way you can test them is with a Volkswagen dealer level scan tool and then replace the part that shows bad.
Well, the flaps or the actuators often go bad. They'll stick then trip a code. You need a Volkswagen dealer level scan tool to bidirectionally test them but if it runs okay and it sticks once in a while you could live with that because it's not a cheap repair
