View Full Version : o2 monitors "not ready"

05-28-2015, 05:13 AM
Hello everyone, yesterday I went to get my car inspected and it failed due to o2 sensor and heated o2 sensor monitors being not ready. I'm currently driving an 05 s4 avant completely stock, i use it as my daily driver and I haven't unplugged or reset the computer since I've purchased the car. I spent a few hours online last night trying to figure out what could be the problem and found a few drive cycle charts so I let my car cool down over night, reset the monitors, and attempted the cycle this morning on my way to work with no avail, all monitor were ready except for the o2 and heated o2. Any advice would be appreciated! Thanks in advance
