I'm taking it in to VW today to have them look at it. Of course when I called, they guessed it was emissions related. The CEL came on again last night...i think this makes 6 times now in the last month. I'll let you know if its manifold related.
Trip to dealership #1
Dealer said that a sensor was sending a fault - related to evaporative emissions. Tech found it to be the sensor used to monitor intake manifold flapper actuation. Said he tweaked the sensor and sent me home. Of course I knew this wouldn't fix it, but I played their game. The next day, my CEL came on.
Trip to dealership #2
Dealer traced the fault to the same sensor and noticed this time that the flappers were sticking. VW replaced the intake manifold with a revised version under warranty. the revised version has lubrication spots that are further away from where the flappers pivot. Supposedly, the previous mani would clog at those lubrication ports and due to their close proximity to the flappers, would cause them to stick. Sounds like a load of bunk, but that's what he said. Also updated the ECQ to increase fuel pressure in the injectors - this is supposed to help as well???
No CEL since, but its only been about 300 miles on the car.
