Front catalytic converter replacement

[gonze]

Hi All

I need to replace the front catalytic converter on my 2016 Caravelle. I have a part number of 7e0254201px super seeded old part number of 7e0254201mx.

I wish to purchase a used unit complete with sensors and pipes etc but have been unable to find one with the exact same part number. However there are a number available that look identical with same sensor locations and plugs. The newer 2020 variations have an additional sensor.

Does anyone have any experience with changing these units, would you advise against getting a different part number?

Thanks

Also I do not have the old unit, hence I need a complete unit.

What did the main dealersay?

They were very help full. It looks like the sensors and pipes routed across the side of the cat are the same across the engines of the T6. But they could not confirm the difference in cat model numbers.
