Default TCU Recoding

I have read most all the threads I could find on recoding the TCU to enable "sport mode". The car is a 98.5 A4 2.8 Q. No luck with any recoding it defaults back to 00000 which is supposed to be Invalid.

The TCU Part # is 8D0 927 156 Q, is there a login code that must be used first?

I searched both here and the Vag-Com mailing list as well.

Default Was that for the dbw 2.8's. I think they were changing the codes to what comes

in the A6 2.8.

to enable sport mode, recode it as 0001X. for my 1.8 default: 00002, enabling sport mode is 00012
