I have a 2016 Yeti, although I've never put bio in it.
As mentioned above the DPF is lightly to be the biggest issue.
Something to keep in mind is these were included in the diesel emissions scandal so could have had the "fix" software, this increases the frequency of regens, not good for you. However the fix can be removed by doing a rollback on the software, this cost around £150.
The Yeti itself is a great car, practical but not too big, and it drives well (it's based on a MK5 Golf).
