Hi Tozo (sorry I dont know your name) I'm in Sydney, Australia I have a C5 RS6 (APR Chip and TCU) I've posted about a 17125 fault and you were kind enough to respond. After a fair bit of research it is obvious that you know your stuff. Is it possible to source a TC from you? And, would you recommend the transmission needs pulling apart given I am now getting a 17114 code.( No noticeable swarf on magnets, no dash code, only Vagcom) Thanks for any help. Rob
