I had a timing chain replacement with a pick up pipe replacement and so far 2 new pvc hoses by a vag mechanic and when they went to turn car on it wasn’t the car i knew. Started angry and then looked like misfiring/juddering and then it cut off. Anyone have advice i can give the mechanics? They have no idea what the issue is. Car was running fine before giving them this job. It would start up fine and run fine. They did smoke test and compression test i think and all came clear. What could have gone wrong during these replacements for this issue to occur out of the blue. Cars mpg is good boost is good gears are good and engine “was” good. Car is around 119500k and thought it was a good time to get these things done before the 120k mark so ye i’m really devastated as this is my main car for me and my family and for work.
