The EPC light came on in my 2000 S4 last week. Would like to find out some more information on what that is. I dumped the codes and found 2 codes related to it... 18098 - Malfunction Indicator Light (K83) P1690 18084 - EPC Warning Light (K132) P1676 I looked it up in the Bentley and could not find anything on these codes??? Thanks, Brent.
