your pic failed to upload in your reply, but if you're talking about the passenger side sensor, yes you can reach it. you just have to snake your arm down in there to get the sensor started. be sure and wear long sleeves and some rubber gloves. i had cuts on my arm for a couple of days because i failed to wear long sleeves. if your pic was of the driver's side, try to send it again so i can take a look at it.

 

I keep getting error messages so i need to resize, but its the driver side, and it is a very tight squeeze, i dont know how to get my arm down there... also where did you put the coolant tank when you moved it? and what tool do you use to actually loosen and tighten the sensor into place?

 

you sust kinda swing the tank to the side. don't disconnect the hoses. as far as the wrench to remove and install o2 sensor, it's a crowfoot wrench. i posted a picture of it on this post.

 

Yeah i went back and saw that, but i noticed the crow's foot with the opening for the wire, thats the part i didnt get, how to unscrew it w/out getting a socket on there, I think i got enough to start, I got the parts and once the weather is a little nicer ill be out and do it. Hopufully ill get a few pictures!

 

Looks like this is the weekend to do it, or maybe next weekend because the sensors have still not arrived. I just ordered them a day or 2 ago though. I will try to get a full write up w/pics

 

Ok, I just got back inside. I went out and removed the MAF? and the tube connecting the AIRBOX to the Y-PIPE. I located the passenger sensor and found tricks on how to do it next time. But i have a quick question. In the Hose to the Y-Pipe there was oil.. Is that normal? I read about it somewhere, but don't think they said why its there and what not.

Oh and a quick warning: WHEN DOING THE 02 SENSOR TRY NOT REMOVING THE TOP OF THE AIRBOX. I removed the top of the airbox and the clip on the back took me honestly 45 minutes to figure it out. I used a clothes hanger but i couldnt get it off. I found a way to stick my hand down there and push really hard and now i got it.

If anyone knows how to clip that clip please let me know. Also What is under the AIRBOX? A tiny tiny piece of metal fell down there (an AIRBOX clip) and want to know how to retrieve it.

Any way next weekend the job should be done!!!

 

Could anyone tell me exaclty which o2 sensors to get from VAST. I went on their site and the offer two versions of the Front O2 sensors.

They offer: All 2.7t pre-02, S4 b5
as well as : 02+ A6/Allroad 2.7t

Which ones do i get with a 00 2.7t, Im guessingthe all 2.7t's and am ordering them tonight unless i hear otherwise

 

Hey, anyone out there, Modset? I got to the passenger side sensor today and had the tool and bar on the sensor, but couldn't get it out. I stuck the wrench and tool on there from the angle of your first pictures of the sensor. Modset said you have to go from the driverside, but do you stick it on there and twist from there? I have an idea, but I need to buy that PB blaster tomorrow and finish the job. If anyone understands what im saying please give me some advice.

Sorry, for spamming the forum with this, but I'm so close

 

TO THE TOP. Someone asked!

 

hey trapped, did you get your sensors changed yet? i just threw a CEL for the driver's side pre-cat sensor. have you done that one yet?
