Hey there, My names Colin and I'm brand new here..I need help or maybe just some info..I have a 09 b8 a4 avant with 115k miles..I love the car..I took it for inspection and emissions and failed horribly with all the codes above showing up..I was quoted 10 grand to fix these codes..I really didn't expect that as the car drives exactly like the day I bought it..I don't know too much about cars but I definitely don't want to sell it as I did my turbo 2000 integra gsr smh, can anyone give me a second opinion on what to do..I was told by replacing the intake manifold it could clear most of these codes...thanks guys
