I was driving my Jetta to a meeting. After filling up with diesel I was merging onto the interstate. While merging onto 75mph traffic I felt the car jerk slightly. The Engine light came on shortly after that. I turned around and swapped vehicles.
A Scan stated it was the Turbo. I didn't think so because the car never went into "limp mode"
I've read thru the forum and narrowed it down to the vacuum lines. I replaced the original vacuum lines (180K miles) to both EGR(N18) and boost(N75) valve. The actuator tested OK under vacuum. The linkage at the turbo was lubricated while I was there. The engine light went away (on its own) after the vacuum lines were replaced.
Yesterday the same thing happened on a 275 mile trip. I noticed it occurs around 70-75MPH when merging or climbing a hill or passing another vehicle where boost is needed. It's almost like the actuator or boost valve is sticking when it gets to a certain value. I don't have a EGT or boost gage to determine if there is a change before of after this event.
Any help would be appreciated.
