View Full Version : O2 Sensor Issue

02-06-2008, 06:04 PM
Car = 01 A4 1.8TQM
O2 sensor called for (universal) = Bosch 15733 (4 wire)
O2 sensor in car = Bosch 17090 (5 wire)

This is the primary sensor (before cat). Everywhere I look shows the 4 wire sensor for my application... but its the wrong one. Look up a 2002 A4 and the 5 wire sensor comes up... which is what my car has in it.

I know all I have to do is get the 5-wire sensor... but has anyone else come across this? Oh, my car is a true 01, not 01.5... AWM motor.
