The question was *how to get at* the sensor, not what to use on it.

Not being familiar with the A8, my guess is that some combination of O2 sensor 
socket, extensions, and universal joint(s) should be able to get to it.

It might be wise to soak the O2 sensor in PB Blaster or some such for a few days 
before trying, as the slit in the O2 sensor socket might be too weak to break 
free a frozen O2 sensor.
