OVERKILL
$100 Site Donor 2021
So a buddy of mine from work, his wife had a TDI that was affected by the buy-back program. This put her into a 2016 Tiguan, which they recently due to mileage and incentives, traded for a 2018 Tiguan when the dealer was blowing out the remaining stock.
Fast forward to last week and apparently she got a CEL, took it to the dealer, and they told her it was probably the intake manifold, and since it was so new, they weren't going to do any troubleshooting, they were just going to replace it. This struck her husband as odd and so after he dropped it off this AM to get this done, he asked me about it. I hadn't heard about it so we did a quick Google and apparently this is extremely common. Not only is it common, but there are three different ways it can fail!
Now, the three components on the intake manifold that can defecate the bed are not available separately, so if any of them sod off, you are replacing the entire thing, which is, according to the dealer, a 4-hour job. This seems... ridiculous? At least the manifold unit isn't insanely expensive
There's a video I found on Youtube when he and I were looking it up that explains the three failure modes:
