    It does sound like that. The transmission should be correctly mapped to the engine so it does change down correctly rather than let the engine struggle. Seems that it could be a simple fix in software if enough owners complained. Unfortunately the number of 200T vehicles sold in the UK was very low. The RX200t sold less than 100 before it was withdrawn.

    I also doubt the gains however the above isn't technically correct. The VVT system uses oil pressure to mechanically alter the timing but the oil is controlled electronically by the ECU via an oil control valve and actuators. It is therefore possible to remap the timing system - typically via a piggyback ECU as the stock control unit isn't reprogrammable. The engine/intake also contains an ACIS valve which shortens the length of the intake manifold, and this does suddenly close which causes some sort of kick and change in noise - this feature is common to many Toyota engines since 1980s.

    The best performance is obtained by having the transmission in auto mode and letting the CVT keep the engine at a constant rpm at the peak power - which is 6,000 rpm. The torque curve is flat between 4,200 and 5,400 rpm so try and keep to at least above 4,200 if in manual mode.

    They should just be inspected regularly after 5 years and replaced when deterioration occurs.

    CEL will clear after three engine start / warm up cycles without the fault. Disconnecting the battery will clear it straight away. If the light remains, so does the fault.

    Toyota/Lexus typically use three manufacturers for their audio and infotainment systems. The US systems have satellite radio, emergency assist, vehicle location tracking, remote vehicle information and service alerts, remote engine start/door unlocking etc. and are therefore quite different even if the same manufacturer is used. The European systems would need different software development to gain CayPlay or AA - I suspect the current systems are capable of offering such functionality - whether Toyota will commission it is another thing.
  7. ColinBarber
    The vehicles in the US have different systems so an update won't work on European models.

    The hot marks are the ones most accurate (cold is used as an initial basic guide if the engine isn't able to run etc.). With the engine running the fluid level should be at the Hot marker, if not you need to add more if under or remove some if over.
  9. ColinBarber
    Are you on flat level ground and the engine running at the time of taking the reading? Ideally you should slowly move through all the gear options and back to park before checking, that makes sure fluid is present throughout the valve body of the transmission.
  10. ColinBarber
    Hardly pointless as it is positioned as a safety feature and it will warn you there is a problem before a pressure gets dangerously low.

    The last was around mid 2005, although don't know if that was a European model. Many vehicles that are in showrooms don't get registered for some time after manufacture. If viewing check the paperwork - I'm sure it is Lexus' records that are wrong but the VIN associated to that registration shows a Cyprus vehicle manufactured in 2002/2003 so potentially could be an import.

    All Lexus models have direct TPMS with valve wheel sensors, but that doesn't mean you will get individual readings - only a warning if one drops 20% below the pressure set when calibrated. I believe only the Premier grade on the GS is able to show the individual pressures on pre-face lift vehicles. All grades have the feature on the facelift models (2016 onwards).

    No not without specialist equipment.

    I'd like to think at 40k they would be more willing to cover this under warranty than at 100k. The main issue is that there is no preventative maintenance in the service schedule to stop this from happening.
  16. ColinBarber
    That isn't the norm.

    I don't believe the cold start injector is fitted to European series II IS250s, although it is to the series III IS250 and GS250. It is located on the common intake and therefore if it was leaking it would affect both banks. The difference in the long term trims could be one or more injectors playing up, or even the O2 sensor itself becoming lazy.
  18. ColinBarber
    No, I'd say the opposite. They expect less rattles, quieter and smoother ride.
  19. ColinBarber
    same on my GS - there is no physical AC button, you need to go through the A/C controls on the infotainment screen to toggle it on/off.

    Seen a few Model X recently - the front and rear door handles are next to each other and the alignment on all the ones I've seen is shocking.
  21. ColinBarber
    Yes probably just slider pins starting to seize. I'd definitely ask your dealer as this should be covered under warranty. The repair wouldn't have anything to do with it, and the dealer will want to get the warranty work - they get paid for it - so shouldn't look for reasons not to do work.
  22. ColinBarber
    Is it near the oil filler, someone may just have spilt some when trying to add some oil to the engine?
  23. ColinBarber
    Lexus have never used a CVT in a vehicle. All Toyota/Lexus hybrids use eCVTs.
  24. ColinBarber
    Indeed they are, but not all LHD ESs are built there. The ones for LHD countries in Asia and mainland Europe aren't made in the US.

    The 'kick-down' switch which presses at the end of the throttle travel.
