having issues with my car 2006 a3 2.0t 133,000, just recently got for practically nothing, it had a dead battery when I got it, I put one in and all it did was crank, hooked it to a cheap obd scanner and cleared the codes, it finally started, idles very rough, and has no throttle response and epc light is on, showing codes p2294,p0300.p0304.p0302, any help would be appreciated!

 

I hade a similar issue, however, I do not remember the codes it thrown. but have you tried changing the cam or the crank sensors?
