This is because you dont have the full version of VAG-COM.

17837 - Circuit for Brake Vacuum Pump: Open Circuit
P1429 - 35-00 - -

This code is there because you have a 2000 S4 and your ECU is probably a 2001 or 2001.5 ECU with ESP for some reason and since you dont have ESP that codes shows up.

You need a New or Rebuilt ABS module

You need a new EGT sensor, also check the connection could be that & the misfire could be anything.

yea, i do have a 2001 L box with hitachi conversion, so that explains that one i guess. Thanks!

Well, there you go

i still get the vibration from misfire, and a flashing cel at times, and limp mode

I'd think the 18057 code could also be because of the L box conversion?
