Trying to make that dastardly light on my dash go out... This is a 99 NB 2.0 AEG engine 5 speed manual.
Have MIL/CEL checking codes with vag com reveals a 16556/p0172 rich code but no others, engine idles fine and drives with no noticeable symptoms. I Did have a few vacuum leaks but I believe all have been fixed now, but maybe not. Block 032 o2 trim readings are -18% and 11.8%, ran some injector cleaner through at the last fillup with no change. Also ran a WOT 2nd gear maf test. Highest level recorded was 73.96 g/s from memory it seems the g/s should be closer to 90? Thanks in advance for any help. I hate to replace parts yet without some certainty that they are indeed bad.
