Today I hooked up a VAG COM that was very generously loaned to me by Paul (TTinGables).
After checking out my engine for suspected Coilpack failure, the only thing that turned up was this:

3 DTCs Found:
16839 - Evap Emission Control Sys: Large leak
35-00 - -
16684 - Shareware Version. To Decode all DTC's
35-10 -Please Register/Activate - Intermittent
16686 - Shareware Version. To Decode all DTC's
35-10 -Please Register/Activate - Intermittent

I know the first DTC is caused by my fuel cap not being on which I lost at the gas station.

Can anyone tell me what these mean? Are the 2nd and 3rd caused by my APR chip being detected?
I was hoping to find something along the lines of "Cylinder Misfire" that would pinpoint a bad coilpack.

I also decided to check other areas of my car like the ABS brakes and the AWD and I got the following codes:


For my ABS BRAKES:

1 DTCs Found:
00778- Steering Angle Sensor (G85)
04-00 - Mechanical Malfuntion

For my AWD:

1 DTCs Found:
00526 - Brake Light Switch (F)
27-10 - Implausible Signal - Intermittent

If anyone can shed some light I would greatly appreciate it! Thank you!

16684 is a combustion misfire and 16686 tells you it was in cylinder 2.

Will do right now.

So I guess it's a safe bet that my coilpacks are to blame, considering the symptoms my car is going under.

Good ammunition to take with me to the dealer.

plugs. Switch cyl 2 coilpack with one that isn't misfiring and see if the other cyl misfires, if misfires stays with cyl 2, it may just be the plug.

Well, at least you were able to get in. Good deal.
