Excessive battery drain Fuse 16

I have skoda octavia vrs mk2 2008.  i have excessive battery drain of  1.4 amps , removed  fuse 16 under bonnet fuse box  and battery drain goes away. have looked in owners manual and it says fuse 16 is for windshield wiper lever and turn signal light. 
But when i pull the fuse  all the dash lights go out ,car wont start , and the fuse also controls the Auxiliary heating water pump .
Does anyone have any advice on this or should take it to an auto electrician .
