Got a cel pulling into my driveway today...got it scanned and p0130 and p0135 shows up...havent seen anything on the forum that really help me out...andbody know what this is or how i can fix it?

No indication from the car at all that something is wrong...right before the light went on the car stutterred for a second and that was about it

**STONER** · 10-11-2010 05:16 PM

Looks like you may need an 02 sensor. But wait your modded, correct?

**Insane_Audi** · 10-11-2010 05:21 PM

coilpacks?

**deeznuts** · 10-11-2010 08:40 PM

yea full bolt-ons, along with testpipe and downpipe

**makav3li** · 10-11-2010 09:09 PM

yea the first code is your o2 sensor, bank 1 sensor 1 i believe is precat and your apr stage II+ anyways so the cat code is already deleted. Looks like you may have a bad o2 sensor, I'm not sure if this is doable but you could take ur aft o2 sensor and put it on the forward 1 and swap the harness connectors and see if the code goes away. I'm not sure if its the same sensor but I believe the only diff is the harness length. And you could just leave your aft o2 sensor out seeing how you have a test pipe anyways. You may want to atleast connect the harness to the aft o2 sensor spot cuz it may cause a diff o2 sensor code than the 1 thats deleted.

**deeznuts** · 10-11-2010 09:42 PM

if thats what it is i might as well just buy a new o2 sensor, no? is this going to be a reoccurring problem?

**viziers** · 10-12-2010 04:08 AM

Well for my front O2 sensor I got this code:

000307 - Oxygen (Lambda) Sensor B1 S1: Response too Slow
P0133 - 002 - Lower Limit Exceeded - Intermittent
Freeze Frame
Fault Status: 00100010
Fault Priority: 0
Fault Frequency: 1
Mileage: 221306 km
Time Indication: 0

Freeze Frame
RPM: 2653 /min
Load: 36.5 %
Speed: 99.0 km/h
Temperature: 88.0°C
Temperature: 29.0°C
Absolute Pres.: 980.0 mbar
Voltage: 13.716 V

And you CAN'T swap your O2 sensors it will not work they are both different in the way they collect data.. Ever notice the huge price difference in both of them?

can anybody else chime in and let me know what this code is for

viziers is right, and you might as well buy a new 1 and swap it out, its not a hard change, u can see it right from the engine bay.

**deeznuts** · 10-12-2010 02:31 PM

Anyone know the cheapest place to order one? Dealership wants 280 for it....i usually get discounts on audi psrts but for whatever reason they cant discount the sensor

**deeznuts** · 10-12-2010 02:39 PM

I pulled the battery, the code went away havent noticed anything else and the car still pulls strong but going to replace it anyway because when i pulled the sensor out today it was black as hell

**TurboKits.com** · 10-12-2010 02:55 PM

Hello Deez,

Typically the O2 codes do take a driving cycle to trigger the CEL again. You can scan and look for any pending codes to see if it is going to come right back. It is probably the heater circuit and not the whole sensor. Also, the primary O2 sensor is used by the ECU to read Air Fuel Ratio. So if it truly is a bad sensor, you will want to change it out fairly quickly and reset the stock ECU. This will allow it to re-learn the fuel trims (who knows if those were thrown off by the sensor issues).

Hope this helps.

**deeznuts** · 10-12-2010 02:58 PM

Call me stupid...but what is the heater circuit and whats the difference between the o2 sensor and the heater circuit?

**makav3li** · 10-12-2010 05:01 PM

the o2 sensor has a heater circuit inside it from what i understand and all it does is heat up the o2 sensor to calculate air/fuel better/faster. I dont think u can change just the heater circuit but then again i could be wrong.

**STONER** · 10-12-2010 05:44 PM

No you need to change the whole thing.

**deeznuts** · 10-12-2010 06:23 PM

you guys have been great help, never had to deal with an o2 sensor before....another questions: ECS tuning and 2-3 other websites ive looked at sell only the sensor, and i am guessing you have to splice into the wires to connect it to the harness.....is that a safe solution to go to, or am i better off paying the 280 dollars and buying the entire cable and replacing it...the reason i ask is because i have found the o2 sensor for as little as 100 dollars...compared to the 280 for the entire setup

**STONER** · 10-12-2010 06:34 PM

I don't like to splice when it comes with 02 sensors. Due to resistance issues that could arise and you might be back to square one. I know other guys will disagree, but for me I don't splice 02s.

**deeznuts** · 10-12-2010 06:35 PM

stoner- any idea where i can get the entire harness for cheaper than 280? i dont like that idea either.

**TurboKits.com** · 10-13-2010 02:59 PM

get the Bosch part# from the O2 sensor and call up Napa or Auto Part Intl. They should be able to do much better than the dealer...

**viziers** · 10-13-2010 03:05 PM

If you can wait Ill get you the Part number tonight when I get home... DO NOT SPLICE.......

The heater and O2 are one in the same! I paid 200 even at my local Audi dealer (Flow Audi Greensboro)
