Hi guys;

An interesting point came up during my conversations with a Mercedes tech from whom my
son was buying his first Audi.  He maintained that the practice of splicing in a generic
oxygen sensor to an old connector (something I've been doing for years) is not a good
idea because it deprives the sensor from access to outside air, which is used for
reference.

He said that modern sensors do not have an opening for sampling  
outside air but instead, get access to it through the wires.   
Consequently, soldering the wires and sealing the connection closes the opening and the
sensor gets no access to outside air.

What do you guys make out of this?
Cheers;
