Hello,
The P15fe code is for the instrument cluster memory has failed. I would remove the cluster and have it rebuilt. there are many places online you can send it into. Here are diagrams to help you remove the cluster and a video showing the job being done on a different car, the process is the same. Check out the instructions and diagrams below.
