A bit of a different issue to any I've seen posted here so before the FL2 goes in for a code read, any ideas what might be causing this?

After a couple of minutes (or a mile or so) of running from cold, the car, FL2, manual 2011 HSE, has a few judders, like it's losing power. This mostly happens on idle or at low revs, not under load. On a number of occasions, whilst in neutral and the clutch out it will stall with the Auto Start/Stop turned off and will start again after I press on the clutch. With the auto start/stop feature turned on, it still has the same issue.

I'm wondering if it's a sensor/switch problem associated with the auto start/stop feature or something else? This issue has happened a few times in the past but is becoming much more common and a pain when in traffic!

I'd replace the crank sensor with a quality replacement first, as they are known to cause stalling and or misfiring.
It's also worth checking the throttle body is functioning correctly, as this can also cause your symptoms. Hyundai Ioniq 5 Ultimate. The family car.

I popped the car into my local garage today and they found no codes! They did say that I should take it to a LR specialist who has better JLR reading setup.
I do have on the odd occasion an issue when in 4th or 5th - the engine over revs sometimes when I put my foot down. This could be a duel mass fly problem and that might cause a sensor issue too?
