You could have a leaking auxiliary radiator - a rock hit my aux radiator and caused a pinhole leak. It always smelled like coolant, but I never got a low coolant warning, nor did I notice the expansion tank being low.
It could also be the O-ring on the coolant line that feeds the turbocharger. That is a common fault on the gas Ingenium engines. 𝟐𝟎𝟐𝟏 𝐃𝐞𝐟𝐞𝐧𝐝𝐞𝐫 𝟏𝟏𝟎 𝐒 𝐏𝟑𝟎𝟎 (Pangea Green over Acorn/Lunar) 𝟐𝟎𝟐𝟑 𝐏𝐨𝐫𝐬𝐜𝐡𝐞 𝐌𝐚𝐜𝐚𝐧 𝐒 (Dolomite Silver over Black/Bordeaux Red) 𝟐𝟎𝟏𝟕 𝐃𝐢𝐬𝐜𝐨𝐯𝐞𝐫𝐲 𝐇𝐒𝐄 𝐋𝐮𝐱𝐮𝐫𝐲 𝐒𝐢𝟔 (Aintree Green over Vintage Tan/Ebony) - Gone 𝟐𝟎𝟏𝟏 𝐋𝐑𝟒 𝐇𝐒𝐄 𝟓.𝟎 (Ipanema Sand over Almond/Arabica) - Gone |

About the coolant smell: the coolant should contain a fluorescent substance, therefore by using an UV-light, a potential leak should be easy to find. Only if it's inside the engine then you would not see it, only in the oil.
About the switching from Hybrid to EV-only mode, I noticed too (having an P300e) that it takes some time. My conclusion was that it has todo with the ICE-temperature and state (it tries to protect it, f.e. the turbine). Question from my side: how do you see how many km the ICE was active?

Good question about the ICE vs EV miles covered. I thought I saw the data on the LR app, I just took another look and culdnt find it in the new app. You can download all your journeys from the app to a CSV file, the EV distance is recorded for each trip.

Your EV heater could faulty regarding the delay swapping to ev mode. Mine was reluctant to start off in ev mode & when in cooler ambient temps (below 10 degC). It went to have the issue diagnosed & EV heater was replaced. It now starts in ev mode & stays in EV except where throttle demand kicks engine in. It took a few days for it to settle following the swap as i think they did a software update too. 2023 110 P400e
