I have a 2007 and been needing to replace the cluster. Have done a lot of research on the subject. The 2007 GTI is a animal of it's own. The part # for a 2007 is 278002217. It fit's nothing else. AND....nothing else fit's it. A lot of people with aftermarket stuff say they will work, but if you ask true SEADOO guys, they say only OEM clusters work as they should. They gauges and light work with the aftermarket ones but as far as CODES and warnings, they don't. And most aftermarket clusters don't clock the hours. I just spent over $800 for a OEM gauge cluster, and that hurt. But at least I know I got the correct one. There are aftermarket ones for less then $200 on ebay and amazon. They come from China and Brazil. Go to Seadooparts web site and check part #'s , you'll see what I mean. 2008 GTI has a different part # from a 2007-I don't know what the difference is but they are different. Also, I don't know if they can be flashed to work- that's something you would have to ask a dealership. Good luck.
