The number of times it flashes 5 or 10, etc. then pauses, tells you generally what the issue is. Mine is doing this currently and I posted about it a while back. Do a quick search and you'll probably find it.
Also, there is a website you can try
clicking here . This is a site that another member (fi347, I think) provided me. Very informative site.
I still haven't fixed mine. I may end up taking it to my local dealer (and wait for it while it's fixed

)
Hope this helps,
