I am noticing I have a check engine light come on. I scanned it and it is an air pump error code. Not the pair codes, just one bank. I also notice it ONLY comes on when driving the Tiptronic in MANUAL mode. If I reset the light, I drove it 800+ miles, no problem. Within the first 5 miles of driving in manual mode, it came on.

The car runs great, no issues other than the check engine light. Cannot find a problem...

Ideas?

 

Also, forgot, I have a 2003 996TT

 

WOW, not a single post or comment on this? Might I be the only guy out there with this problem. That sucks if that is the case...

ok, how about this: Do any of you ever have the check engine light on for the air pump and actually NOT have a bad air pump? I am trying to figure out what could be causing this.

 

Did you check the fuse under the rear deck
