I did, so it must have kept working for a very long time. Fortunately, I no longer have to go through that.

Unless you test or have emissions inspection the 1.9 doesn't make it obvious when the sensors fail. Neither did my 88 Fox.

Well, Bosch invented them, and QC of many aftermarket parts is suspect.  They are used in an extreme heat and vibration application, contain platinum (the most expensive noble metal) and quality is of utmost importance for performance, so you decide!  I ran the original Bosch O2 sensor on my '84 for 250,000 miles, and my '85 has 140,000 miles on the sensor.

  I am replacing what's almost surely a failing O2 sensor in my inline VW motored van and I wanted to see what the List take is on O2 sensors.
There is a pretty wild difference in cost.   But they seem to be simple
things and every car has a few now a days, not many of them seem to fail too often...
  Is it worthwhile spending nearly a hundred bucks for a Bosch to put into my van, or can I use a generic autoparts store brand and expect to get a few years of service from that and much less cost?

  What say ye? and thanks
