I believe this is not a possible option on Uk spec GS models. I wasn't aware any Gen 3 model had it. Mine certainly didn't.

I believe the GS 250 uses the 4GR-FSE V6 engine, as was also fitted to the IS 250. This engine has a timing chain not a belt so doesn't need replacement.

@Mossypossy is correct that it won't be an F Sport but it could be a Sport as there were four trim levels. Base, SE, SE-L and Sport. The picture below is from the 2008 brochure. @Largey888 if you have the registration number I'd say give the Lexus dealership that did the last service a call. My understanding is that the dealerships will divulge details of the cars service history and any other work that will have been done.

The brake disc sizes for the GS 450h Luxury are 334x30mm front and 310x18mm rear. For the F Sport and Premier models the sizes are 356x30mm front and 310x22mm rear. From this link it looks like Brembo only sell the rear disc for the Luxury model.

I used this company when I had my series 3 450h. https://www.onlineautomotive.co.uk/

The parking brake needs to be applied. If it isn't you will only hear the audio.

There were four trim levels of the 450h when launched. Base, SE, Sport and SEL. All 450h models from '06 to '08 had a boot lip spoiler. Dropped from Base and SE after '08 facelift. '06 to '08 450h SEL fitted with radar cruise and sunroof as standard. After '08 became an option. Sunroof was an option on SE but not Sport. SE, SEL and Sport have ML sound system as standard. Cooled seats option dropped from SE after '08 facelift. Optional part wood steering wheel and gear knob available on '06 to '08 SEL now standard after '08 facelift. You can tell an '08 facelift model from the visible changes, namely the side indicators were moved to the wing mirrors from the front wings, a slightly different grille and the lower rear bumper panels are body coloured. Prior to this they were black. There was a further facelift for the 2010 model year with the differences mainly being, externally, redesigned 18" alloys on SEL and 17" alloys fitted to SE, although the 18" was an option. Front and rear parking sensors removed from SE but but were fitted if the optional 18" wheels were fitted. Also a new front grille. Inside the infotainment system was updated with DAB introduced and the tape player removed but the ML sound system was no longer standard on SE. Wood trim steering wheel and gear knob no longer available on SEL. I believe with this final facelift Base and Sport trim levels were also discontinued. The following may be of help. They are pages from the 2008 brochure.

Have you checked that you haven't accidentally pressed the button in the glove box that disables the boot opening system resulting in exactly what you describe. It's on page 30 off the owners manual.

I understand Bristol were very choosy about who bought their cars. I remember reading a story in the '90's about one of the oasis Gallagher brothers wanting to buy one and Bristol cars point blank refused to sell him one!

Can someone tell me how to remove the chrome exhaust tips please? I have looked down them with a torch and it looks to me like some sort of bracket that clamps in four places but I am unable to find anyway to release it. TIA.

These are the ones that fit my GS https://www.ebay.co.uk/itm/10x-Lexus-Engine-Cover-Clips-Plastic-Trim-Fasteners-for-Motor-Shields-Panels/391217719352?fits=Car+Make%3ALexus&hash=item5b1664a838:g:q10AAOSwstxVZ4K~

I do know that the 2010 final facelift of the S3 GS saw the 450h in SE spec fitted with 17" wheels as standard with 18" optional so I would think that you should be able to put 17" on your car. The tyre size for the 17" is 225/50.

I can only think that it became an option due to cost cutting as it was originally standard fit on the Mk3 450h SE-L before became an option (for approx. £3500.00 I believe) only available on this trim level after the 2008 facelift. When the Mk4 was introduced in 2012 it was offered as an option only on the Premier spec. However, I believe it became standard fitment again when the Mk4 was facelifted circa 2015 on both the Premier and F-Sport spec but the luxury spec was dropped at this point.

These are my results. I hope you can zoom in on this.

Sorry Lee, not technically minded so I don't know what your asking.

Having just had mine done, if I can work out how to get a photo of the results sheet on here I'll let you know.

John if you've read my recent thread about the vibration at speed you will see that I also had a problem with the steering feeling light and also experienced, like Lee says above, having to concentrate at keeping the car in a straight line. This was traced to it toeing out and a 4 wheel alignment has sorted this and as a result the steering now feels much more weightier.

Thanks @Chris Skelton. I do check mine occasionally and I also always re-torque the nuts myself after any work done but good advice that I'm sure a lot of people overlook. @Farqui and @Britprius I believe that there is a further problem for us GS 450h owners as in what do you do with the wheel and tyre that has had the puncture after fitting the space saver spare as a full size GS 450h wheel with tyre will not fit in the boot! If you've got a full car that will be a problem. I'm sure I have also read a thread on hear a few years back were the poster was stating that if you use a can of 'tyre gue' it will wreck the TPMS.

But who actually provides the insurance for Tesco? None of these supermarkets own banks or insurance companies so it is provided by one of the main insurance companies under the Tesco name. For example, I know when my wife worked for Lloyds that the 'Sheila's wheels' brand was one of their offerings. The other big insurers will do the same thing and they will all charge different premiums for these different names even though it essentially comes from the same provider. Mobile phones are the same. Tesco mobile is supplied by O2 I believe and BT mobile by EE.

I have checked on mine and the sports button and traction control button are lit up as well so I think you are missing some lights I'm afraid.

Sorry I have no idea how easy they go. I would assume it's the same as a wheel bearing or any other bearing. When they wear out, they wear out. In my opinion I don't think that any particular driving style would cause this but would also be interested if anyone knows different.

Quick update. Been out in the car a couple of times and all seems to be fine. I say 'seems' as I'm paranoid about this especially as I have been told on previous occasions that it had been 'fixed' (by balancing the wheels, etc.) and also the fact that driving on some of the road surfaces here result in the car displaying the same symptoms! I will say though that high speed driving feels fine now, not that I drive fast, but I was able to overtake vehicles (safely) under circumstances I wouldn't have done recently because I knew the car would shake and vibrate. I have my car back again😁.

Sorry just noticed that you have a GS 300 and I quoted the 450h manual but I still think it will be in your manual as it shouldn't be so much different to mine. You state in your original post that you have followed your manual in how to operate it so, if it follows my manual, the explanation for what you need to do is on the following page under a bullet heading 'When the 12 volt battery is disconnected'.

If the battery has previously been disconnected and the roof hasn't been reset page 54 of the GS 450h owner's manual explains what you need to do. Similarly if the windows also haven't been reset after the battery being disconnected page 51 explains what to do.

Had a similar experience about 15 years ago with my wife's 2001 Seat. Turned out to be a faulty ABS sensor.
