Anyone do this test with the hood open to see where exactly the sound is coming from?
Like one possibility is that this noise is actually coming from the turbo. Some turbos make a fluttering noise if you press the gas and suddenly pull you feet, which causes the turbo turbine to stall and...
Yeah that is my main question. This is not exactly a new engine. It has been around since 2021 Lexus NX, and is used for high sale volume models like the Highlander. A quick google search does not bring any major issues related to “2.4 liter turbo”. The only similar issue I came across is a...
If you put the car in reverse with rain sense on, it turns on the rear wiper if there is rain, which goes over the part of the glass that the rear view mirror in behind of. But this should only happen with car being in reverse.
A solution I found is that worked for me 100% of the time is not to put the car in gear until the center screen fully boots. The map on the dash appears after the main screen boots (I assume it mirrors it), so if you put the car to gear before the center screen boots, it gets stuck with the...
Wastegate valve regulates amount of exhaust gas flow to the turbo. Spinning turbine compresses the air fed to the engine, allowing injection of more air to the combustion chamber. Compressed air can cause the lower octane fuel to pre-ignite, which causes knocking.
As I explained above we do not...
For compression profile, I basically mean amount of exhaust gas fed to the turbo at a given RPM to generate boost. For instance, they may have different setting for the turbo wastegate valve. Like maybe (in comparison to Tacoma or 4runner ) LC wastegate is tuned to send comparably more exhaust...
I mean identical engine/powertrains do not necessarily use use the same compression profile. Turbo on the LC may be tuned to be more aggressive compared to Tacoma and 4runner, which would necessitate higher octane . Also, the user manual clearly states that using non-premium can damage the...
You need to save the setting using the button on the drivers door. Press "set" and then select either 1 or 2 to save them. you should hear a "confirming" loud beep. That setting will be linked to the key fob used to open the car, and will be linked with the user profile shown on the center...
