  1. Hi, I managed to get a Techstream working on a virtualbox and make it read codes from my GS430 which I bought couple months ago. I've got a few codes in the 'history' section, which I think I can ignore, but I also have a few marked as 'current'. I googled them, but I'm not sure how urgent they are, so I'd need help understanding. First one is C1241 - Low or High Power Supply Voltage; I understand this might mean my battery will need replaced soon? C1289 - VGRS Control System Malfunction; this one sounds serious, I'd like to learn more about this one too. And a couple ones to do with the reason I got TS hooked up in the first place: C2123 - Cannot Receive a Data from the Transmitter ID3 (Main) - huge help if someone can help me identify which wheel is ID3 (not sure if there is a pattern used or are these to be noted only when sensors are replaced?). And last but not least: C1277 - Initialization Un-Completing; which I guess is to do with the C2123 not sending the data needed to initialize. I'd like to know more, especially about the first two codes, and hopefully ID3 can be identified too. Thanks Lexus owners!
  2. Yep, that did not work. Must be a dead sensor then.
  3. Thanks. The tires seem to hold air fine, so I will first try to reset the pressure at a lower PSI and then perhaps take it to indie see which sensor might have failed, then get a replacement or perhaps just replace them all since they are 13 years old now, especially if I can get one for £60-ish. Thanks for your comments Farqui
  4. Thanks Farqui, I might just do that to start with. I believe the sensors to be originals from 2005. Did you try replacements, did they work ok?
  5. Hi, new to the forum and a happy owner of a GS430 for few weeks now 🤘 So the car gets low tire pressure warning light along with 'check system' and a red triangle, something I had before and managed to reset. Today, I did long distance trip and at the end got the warning lights again. I inflated the tires, reset the warnings and left it for the day on a parking lot. On my way back I got the warnings again, this time they won't reset. After I reinitialize the system (warning light flashes 3 times, I get the confirmation massage) it jumps right into 'check system' etc. and won't reset. I do the reset in P and with engine on. I checked the toggle on front passenger's side (switch between two sets of tires), but it's definitely not making any difference. I think I probably should go to Lexus for a diagnosis and repair now, no idea how much it'd cost and if there is any other way to disable the sensor for now as I want to change the tires and refurb the wheels soon (I hear these sensors may be costly to replace and may break when removing tires/wheels). Any advice on what to do and if there are any other ways to get it sorted? Thanks! EDIT: more googling and found interesting approach I will try - I have set 'pressure initial' at 44PSI so maybe the pressure is too high for the sensor to work correctly? https://www.clublexus.com/forums/gs-3rd-gen-2006-2011/445222-no-more-tpms-warning-light-reset-to-lower-pressure.html
  6. @stevet Sounds pretty good then. I looked into engine carbon cleaning, it's £90 only so I'll do this just as a precaution. Found a way to check for the issue with IS250 (I reckon it will work on the GS300) here. Basically, have the car warmed half way through, go on 4k rpm for 30 seconds and then push it quickly to 6rpm and release quickly. If the engine shudders that's a bad lemon. Having said that, I'm beginning to regain confidence in getting the GS300. I think the 2008 GS300 you were/are driving had an improved engine design with DI and PI though?
  7. Are there any symptoms I'd notice during the test drive?
  8. Hi, I've had enough of other brands and remembering how reliable was my father's ES300 I decided to go for a budget Lexus. It's a GS300 from 2005 (I live in the UK, ES300 was imported). I read stories about people having the car over 200k miles and going strong, but there's lots of stories about carbon build up that scare the hell out of me (mostly US though). I have few questions: - for those who got into owning a GS300 that's potentially affected, did you regret your decision? - there are services that offer engine carbon cleaning - do these work? - I'd be using premium fuel, is it enough to eliminate the issue? The car I'm looking at is over 100k and the previous owner had it for over 8 years, so I assume it should be ok, but maybe he's selling it as it's out of warranty and he's started experiencing said issue, I don't know. There are no outstanding recalls on the car. It's the £305 road tax bracket - but I don't think the higher tax has anything to do with engine redesign that avoids the issue? After all, I just want a reliable Lexus. I'm going to go all the way south to see the car on Friday. I'll need to take it there and then or not. It will be covered with engine and transmission warranty for one year, but I understand these carbon build up issues are hard to reproduce, and from what I red Lexus dealerships avoided responsibility in the past by saying they couldn't reproduce the issue. I'd be more interested to see if regular engine carbon cleaning (yearly?) is a solution (I don't want to add cleaner to fuel every time I top up the tank)? Any other advice and tips will be appreciated! Thanks

    GS430 mpg

    Hi, I'm looking to buy a GS430 2005. What's your city/motorway MPG? I'm light footed most of the time with occasional tendency to speed a bit. Nothing extravagant tho. What's the best and worst you get around city and long cruise?
