Ok Cool sounds good. Thoes links were very helpful by the way, i actually have never taken off all of the engine covers, but i found them both now its just a matter of having the time to take of the y-pipe and get to it! But yeah i can't wait for the DIY!

 

trrapped- here is a pic of the angle to use to get to passenger side o2 sensor. i didn't have to take the y-pipe off for this side. and a pic of the o2 wrench. i taped it so it wouldn't fall into the engine. by the way, were you able to see the driver's side o2 sensor on the exhaust manifoldwhen you removed the coolant tank?

Not yet, i located the wireing to them and saw the general area of where they are, i havnt been able to do anything because its like 10 degrees here and i dont feel like working yet, but in the 1st pic is that where you put the wrench way back there?

 

yes. that's the angle to go from for the passenger side sensor. that's why it's important to have a 24' extension bar. that way, it's easier to get the wrench on the sensor.

 

Ok stupid question - but how do you know if the O2 sensors need to be replaced, and is it better to replace them all at once?

 

Ok, 1 not a stupid question i was thiniking the same thing.... If you have a check engine light and you get an error code p1113 or p1131 you need to replace the first two. (these are the ones i'm in the process of doing. I would say if your going to do one of the sensor 1's (pre-cat) to do them both because their hard and once done you most likly will not have to change them again. Also sensor 2 (post-cat) are really simple to get to and you can see them clearly from under the car!

If you want to do one at a time you could, but why not do them both because you'll know exactly what to do! Then again thats just my opinion

 

That makes sense. I will have to keep an eye out for the check engine light. I really need a VAG-COM.

 

also, they say these sensors are good for 100k miles. bull crap! if you have over 60k miles on your car chances are they are on their way out. better to do them now than to fail emmisions.

 

Haha, Seriously my car has 64,000 on the clock and both sensors are dead!

 

Hey, that is the sensor! Right?

I hope you can see what im talking about, but how in the world are you able to put a new one in the hole it you cant reach down there, what tool or toold do you use?
