Hello, i´m new here and want to disable my DTC for pre cat on my 2,7T - maybe here is anyone who can tell me how this works in German ? - I have read many hours but i´m not sure about it... Or someone could help me for adapting my original file for me - but of course i would understood it really...

I think i only must (read in Tuning s4 wiki)
 Set these to zero to disable rear cat DTC: - (using Tuner pro ?) -
## CDKAT - Cat diagnosis in OBDII-Mode. (ME7.5 vehicles containing CDKATSP AND SPF should 0 these as well).
## CWDLSAHK (0x18663) - Code word for probe aging after KAT[40]

and i guess when i´m done i must correct the checksum - but i have a Little bit fear of chrash my ecu...

Maybe some here speaks German and can tell me a Little bit about it - Thanks !

Bye,
Ben
