Error Code P-208B, New Kubota Tractor, less than 25 hrs use

[berto-bonez]

Hi everyone,

I'm reaching out to see if anyone else has experienced issues with the P208B error code, particularly in hot weather conditions. I'm operating a Kubota tractor an M6S111.

The P208B code relates to DEF/AdBlue thawing issues according to the user manual, but it's perplexing to encounter this in hot rather than freezing conditions.

What's weird is that my local dealer insists the issue is diesel fuel contamination. However, I know to be very strict about handling points for DPF and storage instructions for DEF, etc. I'm inclined to think the problem may lie elsewhere, possibly with the servicing itself.

Has anyone else faced similar problems? How did you resolve it? Any insights into whether this could be related to sensor malfunctions or another underlying issue would be greatly appreciated. I'm at my wits end, and my dealer isn't helping.

Thanks in advance!

The m5-111s I work on had a update on def tank systems not sure if it was same code they replaced whole tank assembly as a unit

Dman, thanks for the info. How long ago was that update? Wonder if the dealership hasn't gotten the memo.

Thanks again
