I don't even know why this is a question anymore. If you want an intake manifold, buy EOS. If you really REALLY don't want EOS, buy something else first, then buy EOS when it's not working well.
Miles aren't really an interesting metric unfortunately. Some of us have had dead batteries after the car sits idle for months or even weeks. You have a lot of shit going on here.. Mostly shadow codes, but, again, the flexray code should basically never happen unless you've got can wires crossed...
Unfortunately I don't, but I just ran into this exact issues with a local guy... I wonder if they broke something with an app update or something. We pulled out an iOS device and the flash worked as expected.
