Last night I posted that my car was dead, https://forums.audiworld.com/tt/msgs/715933.phtml . Well when I returned to the parking lot where I left her, the EPC light went on when the key was inserted. I ran VAG-COM for fault codes and got:
3 DTCs Found:
16622 - Manifold Pressure Sensor (G31): Signal too High
35-10 - - - Intermittent
16490 - Manifold Pressure Sensor (G71/F96): Implausible Signal
35-10 - - - Intermittent
18010 - Power Supply Terminal 30: Voltage too Low
35-00 - -

I cleared codes and started the car. I was able to limp home @ 15 to 20 MPH. The EPC light did not come on, but the Check Engine light sporadically flashed.

Once home, I ran VAG-COM again and got the following codes:

5 DTCs Found:
16622 - Manifold Pressure Sensor (G31): Signal too High
35-10 - - - Intermittent
16490 - Manifold Pressure Sensor (G71/F96): Implausible Signal
35-10 - - - Intermittent
18010 - Power Supply Terminal 30: Voltage too Low
35-10 - - - Intermittent
16684 - Random/Multiple Cylinder Misfire Detected
35-00 - -
16686 - Cylinder 2 Misfire Detected
35-00 - -

My TT is a 2000, 180 FWD very early build, APR chipped.

I will call APR on Monday for their thoughts.

The first two codes point the the MAF. Unplug it for now, and go to your VW dealer to buy a new one ($50). The third code - Power supply - is from unplugging the ECU. Go ahead and clear all of the codes. When you unplug the MAF, you will get a CEL and ASR light. When you put the new one in, you will have to clear the codes again to get it to work properly.

The other two codes might just be from the bad MAF too, but I'm not sure.
