No ideal but perhaps the percentage of bio diesel in the mix? Those high pressure pumps are also a high failure item.
If after warranty many thousands of dollars usually. Best replaced at 100k as a preventative issue. Only around a five hundred dollar part.
Other wise if they shred metal internally it means new injectors etc as well. They are expected to fail at some point. I do not understand the checking of the fuel. Other than for their own research.
They will not warranty the system if they find gas in it is proven. So your guess here is probably right. This also applies to earlier models.
