Only thing I can find on that is:
HFM: electrical fault on the DME 7.8.x platform. I'm not sure which ECU/code you're running on with the V6. Apparently the V8s all run on DME 7.1.1.
HFM is the MAF (HFM - Heissfilmluftmassenmesser (mass air flow sensor))so I'd check there and maybe clean it with the appropriate spray. But I'm just guessing that's the proper code so hopefully someone else will chime in.
