[delanobailey99]

Hey, back again.. Lol just got a 2006 A4, just got back in from the shop that don't know too much about Audi cars. They scaned the car and 3 codes came up. P0234.....P0304.....P0171... Does anyone here had these codes before ? What should get change or looked at ? If possible can you tell me parts # and links or write ups please. Any help will do. Thank you.

For the P0304, I would start by replacing all four coil packs and spark plugs if they haven't been replaced. I'm chasing a P0302 code which is a cylinder 2 misfire. I'm going to change all four fuel injectors soon. I should probably do a carbon cleaning as well.

Okay sounds like a plan. I did change the cylinder 4 spark plug. Gonna go back and clear all codes and see if that's fix. But that not a bad ideas to change it all. Let's see what happens. Thank you for the info.
