When I had my past two clusters in the GTI I couldn't ever get the mpg to read correctly, it was always at 99.9. I switched the vacuum sensor thingy on the back of the cluster and it worked great after that. Just making a note here that vacuum leaks aren't always the culprit in incorrect mfa readings.

Now I'm showing around 30 - 31 mpg, and getting about 27 - 28 when I check trip odometer vs. gas pump readings.
