Mutli codes

[DSM1290]

It started with a P0402 Soni replaced the EGR vavle didn't do anything notice that the throttle body wasn't acting properly replaced that and not I have a ton of codes. Still have the P0402 but also have P1027 p0245 p2102 p2426 p2108. It's an 04 Jetta. Any help would be great.

I might guess you blew a fuse or you have some damaged wire/connects. Record the codes, clear them, see what comes back

I checked the fuses. As soon as I turn on ignition on fuse "34" pops. Any ideas of where to search for a bad ground or something?
