Stop Start Not Available

Possibly, but also if the battery is in poor health that will be the way things are.
One thing to check, look under the bonnet at the earth, ie -VE post of the battery, there will be a "module/dongle" bolted to that post and is part of the -VE or earth lead, if you look closely, you should find a cable form plugged into that "module/dongle" - if that cable has been taken out or left out, that will stop auto Stop/Start "happening", so if it is unplugged, plug it back in and then press in to lock the small tab on the connector.
I'd be a bit annoyed if or when I buy a used car and someone has checked some of the coding!

As far as I can remember mine just says start stop not available. I’ve used Carista to disable stop start on my car as I think it’s a pretty bad idea on a petrol turbo car. Might be worth getting your battery checked, my old Civic had a few weeks where stop start was never available, then one day the battery died suddenly
Thanks for the responses. I have an old VCDS from 2015 when I had my earlier Mk3 Leons but it doesn't read half the modules on this car as the cable/dongle needs to be updated.
Will check the battery connections and also see if my old VCDS gives me any clues in case of a coding change has been made.

Checked the -‘ve post and there is a cable clipped into the module, no signs of anything missing.
Connected Carista and it doesn’t show anything for stop-start but then a google showed that 2019-2020 cars can’t have stop-start turned off by Carista.
going to revive my old VCDS laptop and see if that shows anything.
Not a big issue as I usually turn it off manually anyway but just wondering why it isn’t kicking in like it has in my previous Leon’s.
Mines October 2019, can't see a difference between petrol and diesel as far as coding goes, you're only changing the trigger voltage
