There are many useful threads online listing problems and fixes for the Porsche 944, but I found information was spread all over different websites. I wanted to create a solution to this by putting all the info  - or as much as possible in one place. So over the next few months I'll be releasing a list of possible issues to help others. I hope fellow 944 owners benefit by reading this, please feel free to share your problems and fixes as well.
