Not much to say we tried to turn the car on and it locked up at first and so we pulled the key out and tried to start it again and the EPC light and the check engine light came on, then we drove a little bit, turned the car off and then baxk on a little bit later, and the EPC light turned off, but the check engine light was still on. We took it to auto zone and we got the three codes mentioned in the title. Ill post a pic of the receipts, someone please help us out its a 2008 Audi a4 with 82,000 miles, automatic transmission, Thank you in advance.

 

Looks like ur gonna need an evap purge valve, turbo recirculation valve and a pcv valve. If I'm correct ur pcv valve should still be covered under factory extended warranty .
