OM642 engine help

Hi, i'm having a headache diagnosing a fault with this engine and wonder if there could be some kind suggestions here..?

The engine is throwing one code: PO473.

I've tried an O2 & Backpressure sensor, but am stumped. The car smokes like a trooper, feels like it has no turbo. Flat between 2-3k (rpm) and pulls better after 3k (rpm).

thanks in advance.
