Check engine, pulled up 5 error codes, can anyone identify?
 

2003 A4 quattro 3.0
My check engine light came on and it started to idle rough in park, which had happened a year ago when I got it: the throttle body was bad. That was replaced with another used one and havent had a problem since. Now I had to get off the highway because it felt like my engine misfired or slipped or something, it felt like I hit a pothole or something.

The codes I pulled with my crappy scanner are:
17547
41668
41664
20569
20912

I couldn't find any info searching google and I lost the book that came with my scanner, does anyone have a clue? Thanks a lot.

take a look at http://www.bentleypublishers.com/tec....dtc.table.htm

the only code listed on there was the 17547, which i copied and pasted below. i'll keep lookin for the other ones for ya. Judging by the one that i found, theres something wrong with the injector system


17547: Long Term Fuel Trim Add.Fuel,Bank2 System too Rich
