I think I have seen posts about this before but I cannot find them. Any thoughts/suggestions?
MY21 B4P Inscription Pro Automatic AWD: I like the Stop/start feature. I like it that the engine cuts out if I stop at traffic lights. However it doesn’t work properly if I have Auto Hold activated
The manual says:
“The following is required for the engine to auto-stop:
With automatic gearbox,
• Stop the car with the foot brake and then keep your foot on the brake pedal – the engine stops automatically.”
This works fine on my car.
The manual says:
“The following is required for the engine to auto-start:
With automatic gearbox
• Release the brake pedal - the engine will auto-start and you can continue driving. On an uphill gradient hill start assist (HSA14) engages, which prevents the car from rolling backwards.”
This works fine too.
The manual also says:
“• When the Auto Hold function is activated, auto-start is delayed until the accelerator pedal is depressed.”
This is where the problem is. The engine still auto-starts when I release the brake pedal even though the Auto Hold function is activated and is working ok to apply the brake.
Auto Stop/start with Auto Hold activated
That's strange, it works for me. Mine is B4 AWD automatic, picked up last week. Come to a stop, engine stops, take my foot off the brake, vehicle remains stopped (confirmed yesterday brake lights stay on from reflection in vehicle behinds headlights). Stays stopped and engine off till I touch the accelerator.
How old is your car, think i read in here about a software update changing this behaviour.

Bizarre, mines post February so I would think the latest software, but it does it as expected.
It's odd how basic behaviour keeps being altered, check out my latest post under "what have you just found" re locking.

I've given up using auto hold in the week I've had the car, if I stop at lights, I manually apply the handbrake. The main reason I've given up with auto hold is that I have a gentle slope up my drive to reverse onto, and have to get an inch from the garage door. Auto hold in that situation is a PITA, because you get a "lurch" start rather than a creep...
I posted about this a while back. My problem is that occasionally (last time today actually) when auto stopped at e.g. red lights, and the engine restarts from auto start/stop, the car jumps forward, over riding the auto hold ,not great.
The car will restart after a while if power consumption requires it, that's OK, but it shouldn't leap forward when it does, could be dangerous.
I mentioned this at the first service last December, but the person behind the desk at the Volvo dealer looked at me as if I were some kind of retard and just couldn't understand the problem, and so it persists.

My stop/start still doesn't work with auto hold despite the dealer claiming to have update the software at my service last September and stating that the stop/start was working perfectly! Actually at present the stop/start itself doesn't work presumably because I' ve only done around 100 miles in the last 4 months (Wales in lockdown!!).

I have found that you need to lift your foot off the brake Peddle very slowly and the engine remains off. Then when you touch the throttle, it auto starts up and away you go!

Thanks for your comments and for the link to the earlier set of posts. Looks like this is a known issue which others have experienced and which was fixed for some with a software update. I have had what I think is the latest software update but I will be going back to the dealer armed with this additional information. I have had the car for six months and this will the sixth time it has been in the dealer’s workshop. This is my first Volvo and I have been surprised there have been so many problems.
