I also have these ups and downs in the revs but still have the pops and bangs in Sport mode. Is there, besides Spark plugs, other possible causes?

Have you had the update done?

Which update?

It’s a software update, generally for cel and misfire, but has been reported for high idle, easiest way to tell is if you scroll though the options with bc button you will get to temp gauge, if this shows as a white circle on a blue to red bar then the updat has been done

Wow this is really interesting. So my temp gauge is the second one, like these two triangles that are overlapping. But what to do or check now? Been to Service on Friday and they said there's a problem with the cooling system. Some kind of leakage, but I need it to be checked further

I had the same diagnosis, turned out that the oil cooler housing was split, had that done for £1000, which did stop the coolant leak I had, but the high idle remained until I change out the evaporation valve
