Pre-cat O2 sensor: VAGCOM voltage readings ?
is the voltage readings accurate enough from a VAGCOM?
when searching AW archives, i read some posts about physically splicing wires to get a measurement? why do that when u can get it from the VAGCOM.
Block 33, readings about 1.5V is that normal?
thanks.

You want to read block 031.
Also you only want to read the 02 sensor during wot throttle to see how the car is running. The rest of the time the ecu is using the 02 sensor to adjust fuel trim so the reading will always be changing.
On the 2001 with block 031 you want readings somewhere around .85, if the readings are lower your running richer and if the readings are higher you are running leaner. These readings are for 2001 and up, the pre-2001's are the other way around.
