So the other day i got in my car to go to work and it just wouldnt start. The engine wasnt even trying to turn over, just the starting motion. Today i messed with it a bit more and it did the same starting thing, then it just start to click and i noticed it said "gearbox fault" which i havent had any issues driving so i found this odd. No signs of anything wrong prior to this, up to date on all my mech work. I tried unhooking the battery and hooking it back up thinking it may be a security issue, no avail. Any suggestions would be awesome.

Thanks
Charles
