Would be interesting to hear if anyone's got any updates on these issues? I've got a 2018 R9M single turbo engine and I think it's burning oil, blocking up the DPF, causing too many regens and diluting the oil too quickly. Very interesting to hear Stwve172 info on the EGR system a couple of posts above. I wonder what year engines that may apply to?

Cheers for your reply @ThePlumberGuy. Let us know how you get on please. Wonder what the software update actually does...

No one any further with this? Seems like this particular age of van is very problematic with regards to oil consumption and DPF issues. My assumption is that the the older 2015/2016 models are more reliable.

I haven't found the cause of the issue. I'm on a similar train of thought to David Martindale...I feel like this is kind of a big hidden issue. Whether it is the engine burning oil which is wrecking DPFs or whether the DPFs have an issue, who knows, but something definitely isn't right and could easily be manufactured wrong.

The reason that it's kind of hidden issue in my eyes, is because these engines use quite a bit of oil it seems and that must cause the DPF to clog bad, which in turn triggers a regen too often, causing issues with rings/turbos/bores but as a bit of fuel goes into the oil, the oil use doesn't look as bad as it probably is and then the cycle gets worse and worse as the wear is accelerated but the oil gets changed, the service light reset and the cycle continues because many seem to think this is a fix as the P253F code goes off after this as resetting the service count just sets the oil dilution ratio counter to 0% and once it gets back to ~10%, then the fault comes back. Each regen is about 0.05%, so after approx 200 regens, the code comes back.

I hope someone gets to the bottom of this and one day posts on here.
