What do you mean by a run? I find it takes about 30mins of out of town motoring before a regen starts properly as everything needs to get up to temperature. If my van has not been used for a while (it’s not a daily and never used for running about town) I will give it a run on my commute which is 30 miles of mostly A road and motorway. It is always, always with about a mile to go it decides to start a regen so I take a detour to let it finish. If one has been interrupted it will show as having started (I monitor with Carista) pretty much straight away but takes much, much longer to complete as it needs the temps to get high enough before it’s regening properly. It’s best to keep the revs over 2000rpm if possible during the regen.
So if your runs are 30-40miles plus of open driving then that is good. However, the other aspect is overall engine wear as a diesel takes a lot longer to get to temperature so your short town runs will be on a cold engine all the time which is far from ideal.
I’m another vote for the 150 as that is what I’ve got. I wouldn’t want less power, but also don’t want the complications of the bi-turbo or need the performance. Mine is a manual but in town I wish it was an automatic as first gear is stupidly short. I pull away in second when possible. I’d suggest driving a few to see what you prefer as everyone has different tastes.
