I am working on my daughters 06 beetle,it has been sitting for a while the battery went dead,I charged it up,when I started it I noticed it had the cel on as well as a flashing glow plug light.when I connected my scan tool to it it came back with 7 codes 3338,3373,0245,3101,1495,0322,0341.all these code seem to be electrically related,the car seems to run fine.My question is ,is this normally what happens when the battery goes dead?should I drive the car for while to see if these codes disappear,or am i checking all connections?any help would be great,i am not familiar with these cars
