I purchased the car in 2005. The unit seized up during the warranty period so they just swapped the EGR out with a new unit (the turbo was also swapped at that time) - I'm not sure about the manifold. In 2007 they knew it was a newer unit so they cleaned it and the manifold and they did the same just a few days ago. I’m not sure what needs to be done technically but I do have VAG-COM if you can tell me how to edit the EGR settings? Not sure what exactly is going on so that’s why I’m hunting for EGR alternatives. Perhaps my car was just made on a Monday - July 5th.
