Thought I would share my experience with you all... Hopefully, my errors will save someone from much frustration and stress. Over the weekend, I did my first flash at home, using the uniconnect cable and unitronic stage 1+ combo software. I did this flash on my 2015 Golf R, with about 10k miles. On my first attempt, after getting to 100% completion, I was going through the final start and stop steps and on the last step, hit the start button, headlights went on and I dropped the voltage enough to cause a failed flash. My car was now like a bricked iPhone. I saw many lights and heard many tones that I did not even know I had. I restarted the process and now my cable could not even read the ECU. Yes, I had ignored the advice to connect at battery charger when starting the flash. I should have known better, given that my 2014 GTI is on its third battery. I know these cars cook batteries and I should have used that knowledge to take better precautions. The DAP video online clearly gives this advice and I should have taken it. I tried charging the battery and restarted the process and at the end of the flash, it failed again. In fact, when the lights cycled this time, my battery charger tripped I had another brick. So, off to autozone, new battery, and tried a third time. The software keep trying to reapply the failed flash and I could not get it to proceed so, I had to abort and start start with a fresh flash (after reading warnings about how this could corrupt the ECU). My third attempt worked! With a new battery and the charger hooked up... I was up and running. Hope this helps someone. Use a battery charger when flashing!
