We are going to see more of this. I just replaced that exhaust flapper motor on a 2009 CR TDI Jetta with 130,000 miles and it was completely frozen/rusted. Stay tuned for some Wiki page updates since this appears to be mechanical rather than just flash updated side effects. I will try to have those updated tonight with the basic settings tips.

Here's a lot more info on that exhaust valve and possible maintenance.

As stated above, this seems to be a purely mechanical issue and prevention/maintenance may just be also purely mechanical.

Have Fun!
