I am new to the forum first off. I have a 2012 TDI PASSAT that just started acting up maybe 10,000 miles ago. I have 128,000 miles on it. Here's the issue. If I get in the car whether its cold OR hot out it runs rough, doesn't stall but jerks. This happens right at the 27-30 mph zone. The MOMENT the temp gauge moves it goes away and runs like top and will for the rest of the day but the moment the car sits over night same issue. So basically the issue only lasts maybe 1 mile and than wolla its gone. I took it to the dealership and they checked the injectors, all fine. They heard the knocking which last maybe a few minutes and then it goes away. They said next step was to tear off the top end and start looking for cam issues etc. Don't want to sink aton of cash into it but,,, You can start the car every morning and rev it out to 3-4,ooo rpm and it doesn't stumble run rough or anything. Issue only happens under load. Its almost as though something needs to build pressure and then when it does its TOTALLY fine. Any idea?
