Hello! I've recently got myself into a 2007 Audi A5 3.0tdi Quattro, love the thing so far but unfortunately, I'm having an issue with the MMI, specifically, I believe the AMI. Every so often the system cuts all audio, flashes and then does a mini restart and back to normal. This restart happens every 2 minutes when the car is 'on one'. I also lose all power through the AMI socket to my Bluetooth adaptor (Tune2Air). The restart will happen through any media - Radio, CD, AMI... If I were to hazard a guess it's like something electrical is tripping out the system, either by overvoltage or something like - I've never played with Audi's before so no ideas on what it could be! A video is probably more helpful than me babbling so here goes My OBD11 shows a communication interruption on a fault code 03157 - Display control Unit? I've already: Updated to the latest MMI version Updated the AMI itself through USB using .bin file. Unplugged and replugged the AMI - this fixed it for a couple of days. I think my AMI unit may be faulty - P/N 4e0 035 758A I'm hoping... its not the dreaded B&O amp in the boot! Any ideas or where to point are greatly appreciated!
