Hi,
I need to change my downstream (after cat, sensor 2) lambda/oxygen sensor, but I'm unsure of it's location. Been searching the net and can't find a picture. I've removed the undertray. Is it just before the flexible section of the exhaust, not far from the EGR cooler?
It's on a mk3 Leon 2.0 TDI xcellence.

I have back pain at the moment so can't spend much time under the car searching around and want to do this as fast as possible.
