I struggle to believe a high quality piece of engineering like a TBM has rigging issues. Given the torque of the PT6 upfront, presumably aileron trim via a coolie hat may be required? What does the AFM procedures and systems section say?

It may well have been right as it came out of the factory but subsequent “adjustments” could be at fault.
Got a chance to fly today. Confirm the roll is to right. Below is the trim needed to keep ball in the middle and wings level at about 220 IAS in descent.

That is a lot of trim in that case. Just get a rigging check.
Descent rudder trim would be expected to be quite different to level cruise rudder trim – at least in my TB20 it is.
Of course it is much less critical in descent because the plane will always fly quite fast enough 
Behavior is very similar in cruise. I used descent to test because that’s where airspeed is highest and the problem is most pronounced. I typically descend at 90-100% torque, so it’s not a power off descent. Agree that could influence trim settings. I think I’ll bring the plane in to Tarbes this time. It’s a 1000hr check and there’s a couple of other things that need to be fixed. Pilot door alignment still not done right and also some cabin pressure max diff alarms due to faulty sensor.
Edit:
Was just looking at Ground speed records and look what I found. Could be that my plane is fine.
