It seems an old problem may be back.

When it needs a regen you get to choose to do it on a run where you know you will be driving long enough to let it run its course. If you fail to elect to do the regen within a certain period of time then the system automatically runs the regen and then it is up to the driver whether to keep driving or to stop and risk the impact on the DPF / leakage into the oil.

This would be a software update, presumably, as ultimately all you are doing is taking a feed from the sensor that determines when to run a regen together with toggling when that regen actually occurs. I assume no hardware changes would be necessary to introduce this solution.

I accept this is adding further complexity to an already complex piece of kit, but it is no more than the added complexity of Adblue (if you dont do something - ie fill up the Ad Blue / run the regen - within the relevant mileage / time allowance then you suffer the consequence - which for Ad Blue is that you cant restart the engine, which is arguably harsher than simply risking an incomplete regen).

Just saying, again.

And it was this functionality that was great on the VAG DPF app! If a regen was approaching, I'd do an extra 5-10 miles or so to get it through the regen process before going home. If time allowed mind you.

Not as silly as you imply, according to Volvo, as a result of a spate of O2 sensors sooting up a software modification was made to increase the number of DPF regenerations made. This has increased the likelihood of more aborted regenerations when engines are switched off mid-cycle.
The resultant seepage of diesel from combustion chamber to sump may cause oil levels to rise. A revised software induced regeneration timetable should help to eliminate this, so yes, a software fix for a hardware problem.
I agree that a dashboard indication that a regeneration is taking place would be very useful.

I can tell when my car is doing a regeneration as the stop start becomes unavailable and the icon is crossed and when slowing down at junctions etc there is a distinct deeper exhaust note, a burble sound.
I wish there were a way of delaying it and doing it on a longer faster run as it often happens during a trip around town when driving slow and stopping often.

I'll need to keep an ear out for that. Have noticed at random times start/stop unavailable on some outings, so that could be it!

The 'Car Scanner' app - when properly configured - gives DPF loading and sensor data for my VEA model. Pretty sure it works on older 5-cylinder Volvo engines.

Your reference to the deeper exhaust note is interesting, I've noticed this a few times (you can hear the car stepping down through the gear in a more pronounced way through the exhaust sounds too). I'd never connected it to regen.

Thanks!

Exactly as you describe. Make a note of the stop/start icon next time you hear it, it will be crossed out.

Use a normal OBDII dongle?

How can you 'tell' ?. There are a number of reasons why stop/start may be unavailable. Identifying adeeper exaust note or hearing a burble depends upon how good your hearing is. To surggest such hit or miss methods of identifying a regen is hardly the answer.
Not a 'pop' at you, merely my frustration at Volvo failing to respond to an obvious need over a number of years. The VAG app proves it's possible.

Please explain in very simple terms how to achieve. Hardware, software and set up.
