Look in the MKIII FAQ for a thread on error codes and what they mean. Basically though, those are air intake temp sensor and air flow meter sensor codes... been driving without the AFM connected?

That would set the codes. Clear them and see if they return after a few drives.

Again... covered in the faq about error codes (although it may not be spelled out in which case you just have to follow the link)... But since we're here, pull the EFI fuse for 10 seconds.
