Oxygen sensors

[cabrioman1995]

Hello to all. I am about due for an all around O2 sensor swap on my 1995 Audi Cabriolet. Any recommendations on ease of swap? Bosch universal or OEM, etc. (two downstream and two upstream right) Thanks

I would go for the one that has the connectors already attached. Splices can be unreliable if not crimped properly.

ye, but there is also the luck of a buck.
you could get a good one and do all right.

there is no such thing as " im due to change out the o2 sensors " unless you have a problem with them, these are not service items and dont have time limits

I concur, unless it stuck and Voltage does not oscilate. no need to change.
my dad car had this problem the second o2 sensor stuck at 0.2V. changed it strted to oscilate between 0.1 to 0.7
but if you do change you will get a slight gas improvment, but wtill be bad on you pocket.

hey Cabrioman, I just bought a 1995 Cabriolet myself this week. I'm picking it up this weekend. I want to keep this car for a while so I want to take good care of it. Any suggestions what I should get checked or changed?

I'm not expert but I thought volatge from the O2 sensor was supposed to oscillate from around 0.2 to 0.8 V with an average of ideally 0.45 V, if they don't oscillate, things are right. . If you are thinking of the sensors in the cat, I think they are a different kettle of fish ...

oscillate is the wrong word the sensor voltage fluctuates 0-1 V,

around 0.2 to 0.8 V with an average of ideally 0.45 V
DEFINATLY NOT

[kakarot]

yes it fluctuates,
but if too check it at idle it would look like its oscilates. If it freezes eather high or mostly low, then the sensor mostly busted. or person who checks it checks it wrongly.

The sensor only works from 600F and start to give bed reading at 1000F and up.
