2005 A5 issues

I purchased a A5 recently 3 days later with 151 miles it had a almost complete loss of power. The following warning lights came on EPC, emmisions and traction control. Has anyone else encountered these problems? Any ideas? I took it to the dealership got a loaner after fighting with them, and now they will not tell me what the problem is. I want them to give me a nerw car but they will not any ideas?

VW is being particular with new jettas and there problems. You have to call into vw to report the problem and they work with you, they are just trying to make sure they have faster solutions to problems, all dealers must call so there is one database, easier to help people solve problems. There have been some problems with the gas pedal position sensor not being plugged into all the way, and evap systems not sealing properly.
