N80 purge valve and O2 sensor question..

Hi Folks,

After getting the timing belt done, my wife's little Mk4 Golf hasnt been the same. Fortunately I have a Ross-Tech cable so hooked it up and found the following:

Chassis Type: 1J - VW Golf/Bora IV
Scan: 01 02 03 08 15 16 17 19 22 29 35 36 37 39 46 47 55 56 57 75
76

VIN: XXXXXXXXXXXXXXXXX Mileage: 113790km/70705miles

Address 01: Engine Labels: 06A-906-018-AQY.lbl
Part No: 06A 906 018 GP
Component: 2.0l R4/2V MOTR HS V01
Coding: 00031
Shop #: WSC 30079
VCID: 76E9D64952976BA80B9

2 Faults Found:
16518 - Oxygen (Lambda) Sensor B1 S1
P0134 - 35-00 - No Activity
17834 - EVAP Purge Valve (N80)
P1426 - 35-00 - Open Circuit
Readiness: 0000 0000

So, I've found the O2 sensor, not sure what "No Activity" means, but I presume this is a replacement job.
The piece I'm foggy on is the N80 purge valve, where is this ? ... open circut to me sounds like its just not plugged in.

Any tips where to look ? any chance there's a DIY or how-to ?

So, as an update, I found the N80, the plug wasnt sitting on properly and found a heap of rubber goo inside the connector ?!

After cleaning it up, the connector was not damaged at all, and I simply plugged it in.

After clearing the codes, drove the car around for a bit and it looks like that one is clear, but the O2 has come back. So I'm phoning around now looking for a part.

BOSCH Universal = $162 <-- Online part shop
BOSCH Genuine = $210 <-- Bursons
OEM From VW = $286.65 <-- VW Dealer

Ho-hum, what to do ...
