First time they told me software update on the trans and then drove it to clear the filter issue. I just had a service about a month ago and they also did a software update on the trans so am not happy that this was the problem to start with.
Has anyone had this happen and what was the final fix? I have researched a bit and it appears to have been a problem for a few others most fixed by a manual burn at the dealer.

There has been a long list of owners with this problem here:

I don't understand why they would flash the trans and then drive it, that doesn't make any sense. There is a flash that helps with the problem, but they should have forced a manual regen. If they didn't manually regen, then it is no wonder it had the same problem again.

There seem to have been multiple issues around the dpf, there are plenty of owners who have had the alert come up, and driven at highway speed, but the regen never completes. It seems to be a software issue (although that info from 'the one' could be a reason the regen is never completing).
Other owners have found there is a dead sensor (or sometimes a kink in the tube between the sensors that measure air pressure) which makes the system think the dpf is full when it isn't.
And another theory is that there is some kind of coating on the dpf that is interfering with the regen process.
