Have you read the codes with VAG-COM yet? If not, that's the first

The reason why that is having issues is because I could have a faulty oxygen sensor that was contributing to the problem over time. So replacing just the o2 sensor won't necessairly fix my immediate power problems. It would just stop the blockage that's already there from getting worse.
