Hello guys and gals, this is my first of many posts. I've been using a previous employer's VCDS on and off for a little over a year but not for anything too deep. A little back story:
I purchased a 2005 MK4 Jetta 2.0 BBW with 69,xxx miles last August for $3,000. Car was in excellent shape and it seemed like a pretty sweet deal. The CEL was on and I pulled a p0171 thinking it wouldn't be that big of a deal. The previous owner bought a new OEM MAF to correct the issue but to no avail. I noticed the intake boot wasn't secured properly with the factory clamp so I positioned and checked everything to ensure I would get a sealed condition while I smoked the intake. After finding a small crack in the plastic oil dipstick housing, I ordered a new oem replacement from WorldPAC. After it arrived I cleared the codes and took her for a drive. After 3-25 mile highway trips at 55ish (I live in NYC so this is incredibly hard to accomplish) I was able to complete almost every monitor except EVAP and Secondary Air. As I came back to the shop I noticed my Long Term Fuel Trim had creeped back up around +10. As I attempted to force the monitors I completed EVAP but Secondary Air failed to execute and the CEL came on. I cleared the codes and took her back out for another highway drive and carefully watched the Short Term and Long Term trickle up after I hit 50mph. Air Fuel sensors/ o2s appeared to function normally. Something else I noticed but it could be completely normal as this is my first VAG product, the Secondary Air pump will run from start up but not every ignition, even on a cold start. It also runs when the car is hot during random driving conditions. Is this normal? Could my creeping lean and random SA operation be PCM related?
Long story short I bought my own VCDS and I'm going to get to the bottom of this. Below is the auto scan:
All monitors were complete except for Secondary Air which had failed at the time of the Auto Scan.
Any help would be greatly appreciated. I no longer work as an automotive technician for my day job (I work on trains now) but I periodically have access to a lift and various other shop equipment. Thanks for taking the time to read this, and if I can help anyone else out with my experience please don't hesitate to ask!
