There is no mention of IGN status within the guidance doc but the module does retain a history of battery condition, which is used to determine battery working capacity used in determining if electrical consumers should be enabled or not (i.e. seat heaters) when IGN is on. It's a complicated system and not well described, presumably because they expect the technician to have training?
During normal running the only return route for current is through the car body, so passing through the battery monitor sensor connected between the negative and body. If the trickle charger is connected directly to the battery terminals, the current would take the shortest/easiest route, which is through the battery?
I understand that but my point was to do with the car's monitoring system. If one were to connect directly to the battery terminals it would not pass current through the battery monitoring module. I agree it makes no difference to the charging of the battery but does to the car's system. Mercedes workshop files state to connect across the BMM so it and the car system knows the battery is being charged.
Could it be that by connecting via a body part the battery monitoring module (if fitted) can detect the recharge, so the car's systems know? Certainly with my Mercedes it was always recommended to do so, for that very reason. In fact that's how the Mercedes dealer fitted the CTEK permanent charger connections for me.
Their value is likely to drop, initially, until they become rare enough to be desirable to those who can afford the inevitable high taxes linked to owning/driving them, then as classics their value will rise. Get in now, while prices drop
Putting tint over the dials will only reduce the light coming from them. You need to reduce the amount of light falling onto the dials/screens. Maybe some sort of anti-glare film (a matte effect) may help. I thought this was applied to the multimedia screen as a standard (people have commented on it coming/wearing off after 'enthusiastic' cleaning.
Have you tried speaking with Lexus?
Don't you mean the base RC has Tahara synthetic leather, (with the option of the leather pack giving smooth leather) ? The brochure you linked clearly shows the F-Sport RC comes with smooth leather as standard
Well, the full spec sheet I downloaded when deciding on my 2019 (face-lift) purchase shows smooth leather seat material for both the F-Sport and the Takumi grade.
