Default Pre-cat O2 sensor... How the @#$%#$ do you get at it?

I am stumped. I've got the new sensor but I can't figure out how to get an arm in there to get it out. Anyone do this b4? It's on a 2000 180 Quattro.

Default Is it not easy to get to once you remove the turbo pipe? I have my sensors, but haven't dug in for

it yet, but it didn't look that bad...

Default

Drop the pipe out from below or access from above, it looks pretty confined down there.

Default My thought was to remove the pipe in the top left portion under the hood (the one with the

"no hands/hot" pictograph), and get to the O2 sensor from the top of the engine bay. It is tight, but I thought it looked doable. I have not tried it yet, though.
