Hi, I'm a newbie on the forums and still very wet behind the ears using VCDS. I had success using it on a few VW Passat's in the past. So, I'm contemplating a purchase of a 2006 A8 with the 4.2 under the hood. 143K miles on the clock, but overall runs good no CEL or SES lights illuminating. Im unable to run auto scan and I'm unable to access any modules aside from 01 engine. I'm experiencing issues with the MMI, it turns on opens and then shuts off and closes within 10- 15 seconds when and if it should decide to do so. Any suggestions on that and also would this have anything to do with the limited access to VCDS? I've read there's a fiber optic loop in this car and I'm not sure if this loop which I believe is my issue with the MMI would have anything to do with my communication with the modules. Thanks.
