Golf/GTI VI :: 2012 - Cranks Up And Then Sputters Out - Keep Getting Waning Messages

Well, after owning 4 other VW's, this one has left me "stranded". I bought my 2012 Autobahn GTI back in September and it had been absolutely problem free up until now. I have the APR flash and Carbonio intake as my only modifications for reference.

I drove over to my girlfriend's house yesterday around 5:30pm, had no issues or anything up until this point. I get into my car around 10:30pm, ready to go home and push the starter. The car cranks up, then sputters out. This has actually happened once or twice before when I pushed the starter too quickly, so I chalked it up to that. I push the starter again, I get a click, and then nothing. A ton of warning lights come on, I get a couple warning messages come up, one about an error with the ESC, and one about the adaptive lighting system. The car's fan turns on, as if the car was running.

I try to start the car a few more times without any luck, and keep getting the same warning messages. I then got out of the car, locked the doors and let the car go to sleep. I wait 15 minutes and try starting the car again, still can't start. At this point I'm pretty much ready to throw in the towel, but I decided to disconnect the battery for a few minutes, hoping that when I reconnect I'll be able to start it. It still didn't work. At this point I know I'm going to have to take it to the dealer, so I try to put the car back into stock mode. I couldn't even do that.

I ended up having to call roadside assistance. To add to my frustration, I requested a flat bed and instead a front-wheel lift one came. I had my car towed to the dealer, had my gf follow the tow truck to the dealer and filled out the night drop off form and left my key.

This morning I call the service department, trying to inquire about my car and the service adviser tells me "your car has severe electrical issues and we are not going to be able to diagnose them today." He asked me if I had any performance software on the car, and I tell him that this is my 5th VW that I've owned, and that every one has had the same APR software on it. I had my car flashed back in September or October, and that I've never had an issue with it with any car. The service adviser then tells me that this is going to have to go to his manager to write off on it if they determine this is caused by my flash or not.

Now I'm stuck without a car, at least through Monday. I asked for a service loaner and they told me they had none and that since they are closed on Sunday, the soonest I might be able to get one is Monday. I just started a new job and have no vacation time saved up, so the timing of this is certainly not ideal. I know that I assumed responsibility by getting the flash, but I've got my fingers and toes crossed that they don't point the blame on the flash and make me pay out of pocket for this.
