Reasons for Stop/Start being unavailable
Hi folks
Stop/start hasn't been available on my car for a while due to the battery being too low in charge Last night I needed to make a 75 mile round trip. During the outbound journey, I had the following messages in the DriveE menu Electrical system i.e. battery charge too low Outside temperature. It was -3C Engine system On the return journey, the Electrical system message was gone but I still had outside temp (-7) and Engine System The only previous time I've seen Engine system is when the engine is still warming up or it's doing a DPF regen. Engine temp was right in the middle of the guage and I'm pretty sure it wasn't doing a regen as the MPG was OK so I was confused as to what might have caused it I found the following on the Volvo website but it's not very detailed I wondered if there was a comprehensive guide available that describes the conditions behind each message? Cheers |
Hi, I’m pretty sure that I read on one of the platforms whether it was this one I cannot remember, but if the outside temp was “cold” , stop/start would not engage. I’m not 100% on that but sure I’ve read it.
Can’t help with msgs. My experience with stop/start have been when unavailable, I bought a new smart charger then did that “Okey coky ”thing with the buttons ( push this one then push that one then say the Lord’s Prayer),and we where away again. But of course the reset may not be the same on all motors. |
Yes, I'm pretty sure it's unavailable below 0c and above 30c
I'm just confused by the engine system message unless it's related to the cold outside temp but I've seen both those messages on their own previously when the temp has been really cold |
Check for stored or pending DTCs?

Drove it today and it was available again. I did have engine system message for around 10 minutes after starting but that's pretty normal
Although the list above is comprehensive, it doesn't link the conditions to messages on the display. Most of those conditions shouldn't have applied after 35 miles of easy A roads. The only definite was that it was -7c so I'd expect the outside temp message Outside temperature, driver unbelted, climate system, electrical system are all clear but engine system is so vague. |
