Your O2 sensor is a wideband sensor, you need to get the one that matches it. In addition, generic sensors rarely work perfectly, since the oxygen source for an O2 sensor has to come from outside the sensor, and it uses the sheathing of the wiring to do this. A spliced connection will not do the same as the stock harness.

here is the key that came with o2 sensor
VW Mechanic: gomi_otaku, VW Technician replied 2 years ago

But your sensor has one wire less than the stock sensor- there's no way to make it work.

You can buy OEM parts for VW from Partsgeek, at about the same price that an employee would get at the dealer.

ok, not sure if that was worth $28 since I was about to that anyway but figured you guys might know a bit more. Thanks anyways.
VW Mechanic: gomi_otaku, VW Technician replied 2 years ago

It's worth it to use the OEM parts- I have worked in shops that use parts from the Auto Value, Napa, or O'Reilly's, and more often than not they are bad out of the box the first time, or fail within a few months.
