errors in Rheingold- 1B8004 and 20AB08

Got the following errors when I used Rheingold for the first time yesterday and I could not find any of these errors when I searched. No CEL or lights on the dash:

1B8004 Environment air catalyst sensor, temperature- coolant temperature, radator out...

20AB08 Engine cooling system: no emergency operation signal at coolant pump

Along with 4 other errors related to other stuff, which I kind of have an idea to resolve. Has anyone encountered these errors?

Still have 3 weeks left on my original BMW warranty so I can take it in if it's not an easy fix. Thanks.

Was able to fix these errors in the DME by correctly coding for the rear fog light switch. Checked on Rheingold and these errors went away. Strange that an error in the FEMBODY would trigger these errors in the DME.
