Hi I have had 38kw since December 2019. When charging at 7kwh AC chargers in hot weather car cuts charge rate after 30 mins to 3.4kwh. If run air con charger goes back up to 7kwh after few mins. Cant hear any fans running when charging under bonnet. Used car scanner to take snapshot of car. Onboard charger show Temperature of 71 c just before car cut charge rate. The fault happens on all charge posts. See screen shots of car.

71C is very hot. Curious if this happens at all SoC levels, or have you only noticed it in the 85-90%+ range?

It happens at all charge range. Only started on hot days. Back to dealer hope they can fix it.

I believe there's a heat-exchange coolant loop sandwiched 'neath the OBC which is integrated with the A.C/Heatpump system, one wonders if a fault is present in the control logic or valving which is leaving the OBC unchilled.

I think your right will get dealer to test cooling system. Had no problems with rapid charger. Think DC charging only uses obc as switch to connect hv battery.
