homemade air/fuel gauge...

[Gerard]

Uhm... 2:50am in the morning. Should've done a search for this thing
before asking the question, so to answer myself... VW part number
021-906-262-B for the wideband O2 sensor and costs $28.99 from
1stvwparts.com but apparently not as accurate as another version of the
sensor. :) Good info on http://wbo2.com
