I'd check for correct push rod play, in case it is too tight and applying pressure all the time. When hot also bleed the system, if fluid comes out with force when you first undo the bleed nipple on the slave cylinder then there is clearly pressure in the system when there shouldn't be, which could be the lack of free play and also air in the system. m_cl_0002.pdf

Excellent 🙂 FYI, cooper grease shouldn't really be used on moving parts as it is abrasive as will cause wear.

Is it only a premium nav feature? The Exec only has standard nav.

A series III or series IV?

According to the European schedule there isn't anything that is needed at 100k other than the standard 20k service, but I believe Lexus UK change the engine and inverter coolant at that interval.

Try cleaning the cabin filter, and run the fan on full speed with the filter removed for a second or two just in case there are leaves stuck in there.

The official Carista adapter gives you 1 month's access to the full application, which may be all you need if you want to set customisations. Doesn't seem to be available on Amazon at the moment though.

Pads are normally 12mm new, and ideally should be replaced when down to 2mm. At 5mm you still have quite a bit of life. The dealer is probably mentioning it because they don't think they will last 10k miles before they see you again but you don't have to get them done straight away. I'd also question if the discs need replacing. They should last two or three sets of pads so maybe the dealer is trying it on.

It should be fine. It is Ethylene glycol based which is important, but whether it protects as well in unknown.

Seems most of those changes (engine tweaks, final drive ratio, suspension) will come to the standard RC F too. The RC F TE gets weight saving, aero, and interior trim changes over the standard model.

In some ways I prefer the interior compared to the ES. Doesn't have the stupid stuck on Nav screen, nor the horns at the top of the instrument cluster.

All grades now have LED lights. The F Sport and Premier get triple LED headlights with automatic high beam.

not that it is the best way to test it - a scope looking at the waveform would determine if it is functioning correctly.
