Works good engine runs much better - old unit was opening much sooner it took the engine 5 miles before it got to operating temp.

Fixed My Issues

Coolant never reached temp on dash or in vag-com, installed this little fella and now I sit in the middle and better yet my average MPG has gone up. Will have to wait and see how this performs in the hotter NC summers, but I imagine it will do fine. The provided o-ring also sealed perfectly, first try unlike all the other O-Ring horror stories I hear.

Some of the reviewers above may have been rewarded for their positive & negative reviews. We don't hold anything back.
