Can anyone help with this one ?

Well here goes,

The good old engine electric has been on for a while, and when i download the system with vag-com i get the 2 following errors in the engine module,

1. Camshaft timing adj (bank 1) intermitent
2.EVAP purge valve intermittent

I decided to have a look through every fuse, I came across 2 that had blown 1 for the heated rear windscreen and the other (fuse number 30 ) for the engine electric system.

I cleared all the fault codes and reset the light and replaced both fuses,after a day of driving without the light coming back on,the next day i started her up to find the light on again. i checked fuse number 30 and it had blown again, ive now tried the above 3 times but fuse 30 keeps blowing.

Does anyone have any ideas why it my be doing this.
