Nothing is impossible with enough drive
If you're talking about the 1.9 TDI like what's in the mk4/3, that engine is seriously too underpowered to move a B6. I think there's yet to be a diesel A4 stateside
Can anyone tell me if this is possible?
Was the 1.9L I4 TDI or 2.5L V6 TDI sold in the US?
Would the tranny need to be replaced also?
What about gas tanks/lines?
I woke up wondering this and can't find the answers. My guess is that is practically impossible.

With a tune, nozzles, and an exhaust the 1.9t wouldn't be bad in an A4. Hell, our B6s are only 250pounds heavier than the Mk4 Jetta I used to have. Run some lighter wheels and maybe even upgrade the turbo on the TDI and you'll be having a blast with 300 ft/lbs of torque while still getting 40mpg.
