The heated element provides for better control of emissions
in the "start" cycle phase of fuel controlling.
Reason being is the non heated sensor takes quite a few
of driving to get up to operating temp, and operating
By using a heated sensor this operating range can be
achieved much sooner!
Then as an auto manufacturer, you can claim better emission
"overall" since the emissions starts controlling sooner,

There are 3 sensors that can be utilized on your coupe!
1-the 3 wire heated, but depends weather you use the Audi
part #034 906 265F
or the Bosch #.(0 258 001 051)
2-the Bosch 1 wire, standard part, Audi#200 906 265,
Bosch#(0 258 001 026)
3- the Bosch "universal", Part #(0 258 001 027)
The Bosch Universal I aquire from Autozone for $20! So I
have to solder in its wire.
Functions the same as all the above, and costs the least

The heated unit costs over $100!
