All sorted now Found this weblink from our US cousins ... https://www.clublexus.com/forums/is-2nd-gen-2006-2013/851600-engine-not-responsive-check-system-and-vsc-are-lit-after-replacing-fusible-link.html It turns out there are 2 fuse boxs in the is250 which according to the manual is a type A and type B. The manual isn't clear as to whether the car has both or one ( I assumed the manual covered different models). I checked the second fuse box as per the above link and it was the exact same ETCS 10amp fuse. Replaced it and jobs a good one! Annoyingly, while I was replacing the linkable fuse yesterday, I didn't notice the second fuse box and assumed it was a air filter housing. So the moral of the story... Don't buy a bleeding Mercedes!!!!!

Hi Paul, I couldn't find anything here using Google search but a few similar issues came up on US forums. I've so far exhausted everything although still researching. I've disconnected the battery again just now and will see if a few hours will allow the ECU to reset itself. I'm hoping the ECU itself isn't damaged

Texas: Thank you... I've tried that but unfortunately it didn't work. Madasahatter: A friend has a cheapo one from eBay. I will give that a go later today. All the suggestions and more are welcomed. Many thanks

Hi all, I hope you can help. Wife's Lexus had a flat so in my wisdom, I decided to jump it using my Mercedes. Stupidly, the Mercedes dealer at some point placed the red battery cap on the negative terminal and the black on the positive. Not double checking, I inadvertently connected the terminals incorrectly and well.... you can guess the rest. I checked the fuses under the bonnet... The fusible link was broken (it looked like 19 - Alternator 150amp). The car still started but the dashboard was lit up like a Christmas tree and the car was in limp mode. The central locking didn't work nor did the electric seats (I didn't test everything at this point). Lexus wanted £130 for the fuse but then I found one for £30 off ebay. I replaced this yesterday and there was certainly some improvements. Car started but only the engine management light and VSC was on. Car is still in severe limp mode (barely revving). However, central locking and electric seats now working. I have checked every single fuse under the bonnet (1 x box next to the battery) and the 2 fuse boxes beneath and either side of the dashboard. I haven't checked the relays yet as I need a multimeter but can't see how Noise Filter, Defog, GLW RLY2 (Fan no3 Diesel), Head LP, GLW RLY1 (Fan no1 Diesel) or Starter could be causing this. Can anyone assist further in helping me diagnose and hopefully resolve. Many thanks :)

Yeah doesn't seem like it. I'm on the hunt to replace my bulbs. I simply don't enjoy driving at night anymore. I've looked through the threads but can't see any other recommendations. Any ideas?

Hi Paul, How did you get along? I want to upgrade my bulbs... I'm surprised the current (non hid) setup passed an MOT to be honest!

Thanks guys, I swapped them around and believe it is the bulb itself. I'm not too impressed with the bulb going this quickly on the car. I'm going to see if I can source the bulb locally tomorrow. However, I have found the following suppliers which seem good value. http://www.autobulbsdirect.co.uk/philips-d4s-oem-replacement-xenon-hid-bulbs.html £46 http://www.ebay.co.uk/itm/Philips-D4S-XenEco-42402-Xenon-HID-Replacement-Bulb-Toyota-Lexus-IS250-4300K-OEM-/280792038578?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4160827cb2 £61.50 http://www.convert2xenon.co.uk/xenon-hid-bulbs/557-philips-d4s-hid-xenon-replacement-bulb-42402.html £55 http://www.xenons4u.co.uk/hid-xenon-bulbs/17-philips-d4s-xeneco-42402-xenon-bulb.html £50 + PP Hope the above helps.. Cheers again

P.s. I'm about to starting swapping the bulbs around etc to see if I can narrow down the issue

Hi all, I have no past experiences of Xenon lights however I was under the impression they do last a while. My vehicle a "56 plate" GS450h which I've had since new and has only covered 25k has an issue with the driver's side headlight. When I turn on the light, it turns on for less than a second then goes off. The passenger headlight stays on as normal. I was about to purchase a brand new bulb but don't really fancy doing so unless I know it is the bulb that has gone. Has anyone else had this problem before? Does it need a new bulb?

hmmm... I thought they came as standard on the hybrid versions?... I was planning on drilling a hole in the side of them for the sake of curiousity!!.. They are the original tyres which came with the car. I am pretty sure they are run flats. Otherwise I've been suckered by the dealers!!.. Can anyone comfirm whether the GS450h comes with or without runflats? I have the Se-l version. Regards

Yes, another tyre thread ... Just come back from two different high street tyre places.. One being Kwik Fit and the other being Autocentre (Big green building) Anyway, I'm not a big fan of runflat tyres... The rides abit harsh and tyres are quite noisy. Went to Autocentre first who advised me that I will need to tell the insurance company if I replace the existing OEM runflats with standard tyres? Apparently it can invalidate the insurance? Anyone else come across this before? I generally don't mind telling the insurance but I'm pretty sure they'll slap me with a £30 admin charge for telling them!! Then shot off to KwikFit, and they say that the car should have the runflats replaced with runflats as the suspension is set up for these tyres... I followed this with - If the tyre is the exact same size, exact same shape and can equally carry 800kg plus at each wheel, in what way would the suspension be set up differently??? I got a blank response to this... Anyway, I thought I would ask the experts here... Is it okay to replace my tyres with non-runflats? Will it invalidate my insurance? Will it ruin the setup, ride and handling of the vehicle? The car is a GS450h and came as standard with the horrid runflats... Any thoughts and opinions appreciated... Regards

Agreed... However, I am not expecting people to trade over the internet. I am expecting people to trade face to face. This is simply a central hub for car enthusiasts to sell on. Hi Steve, Yes. Advertising the forum is going to be a big challenge. Hopefully, if I can get a handful of people using it, it should grow further from there. I am not sure what you mean by your second sentence though..

Hey Guys, Haven't posted here for a while but just wanted some feedback from the you guys. Recently, I had a brainwave and decided to setup the following website. http://www.petrolHub.co.uk In a nutshell, It's a site which users from different car forums can use to advertise goods they have for sale. Pretty much like a central hub to gain a wider audience amongst the car community. I thought it would be a good idea as quite often, the thing you want to sell would be of interest to others from different motoring backgrounds. My web design skills are pretty useless as you can tell but would appreciate some feedback of the idea and if you think it is an idea that would eventually get a good flow of traffic. I am planning on using wordpress to revamp the site but that won't happen for a while as I simply don't have the time. Currently it is in a phpBB format which most car forum users are familiar with anyway. Any feedback would be greatly appreciated. Please go ahead and browse through the forums and let me know what you think. The site is pretty much live now so go ahead and post as much as you want. Regards Imran

Yerp.. Mine was doing this too.. First my passenger side failed.. I reported it to Lexus under warranty.. A day later when my warranty expired, the problem switched over to the other side!!!.. They have since replaced the passenger side and I am currently waiting for the problem to occur again! :)..

Has anyone aware of any recall issues on 2006 GS450h?? I phoned my local dealer for a random enquiry and he told me the car has a recall issue with the rear brakes and the steering rack. I didn't get any letters and nor is it listed on the Vosa website... Anyway.. This was a week ago and my car has had the repairs done. I just thought I'd let you guys know incase you are not aware. My cars on a 56 plate. Regards

No mate, the key is only needed for the start button... have you ever tried starting your car and telling your passenger to walk away with the key... The car still drives for miles!!!!!!! lol... interesting security!!! :winky:

Was there an RAC or AA patrolvan nearby?? They have some sort of wierd communication radio thingy which jams the immobilisers on all cars nearby!!.. I remember when my old car was being sorted by the RAC man and he had the local policeman baffled when he couldn't drive off in his brand new Toyota Landcruiser!!! Was good fun watching it!!! :winky: Ps. While we were playing with his "jamming" device, I tested, my Lexus which wouldnt start yet my VW passat did!!.. maybe different frequencies or something....

Maybe the cold weather??

Hope the picture above is good. Found it on google! The boot is not bad. As said above, it is the same size as the Focus. I looked at the positive side of it! My boot is an excuse to not do airport runs!!! :winky:

Not so much a bad point but I will add what I believe would be a common complaint for a new GS450h. When I purchased the car in 2006 brand new, it was claimed to be an alternative to the Mercedes E320cdi and the BMW 535d. Ok it has similar performance as the other two but its no where as near as good on fuel with them unless you drive the car VERY carefully. I wouldn't buy the GS if you are looking for fuel economy as good as those tractors out there!... However, the fuel is pretty decent for a car of this size and performance so its not too bad!! ;) Favourite feature for me has got to be the silent "Start" button! Those who have experienced the start button will know what I mean! :winky:

No seriously... Driving home yesterday she decided to lose power and give up on me!!! Tried to start the car up again and nothing... Everything lights up but just won't start. The dash still reads "ready" when starting the car but wouldn't drive... RAC took her away and should be at the dealers today... Anyone have any ideas what went wrong?? I'm not really that worried as I know Lexus should be able to sort it out but just really curious!.. Never expected a 1 year old, 8'000 mile Lexus to break down!... Anyway... I might give my Pug 407 a thrash... The nice guys at RAC let me have one for a few days!!! :winky:

Never really noticed... Im getting 27-28mpg on a warm day... been told its not very good... But also consider that I don't drive it much, Alot of cold starts and short journeys!

I think Road tax is £190 for the year.. This was put on by the dealer so can't remember the exact figure... It was also before the recent budget so it may have changed... I've never had it serviced but expect typical stealer prices...

I've got one... Fantastic cars... Its a little strange to get used to the CVT gearbox... (its like an ON OFF switch next to the brake pedal)... At the moment, around town I'm averagin around 27 MPG... I don't push it at all so keep that in mind.. If you buy this thinking your going to get Diesel economy.. DONT BOTHER!!... Otherwise it has amazing MPG compared to similar cars... (E500 etc)... Any questions, give us a shout... Mines on a 56 plate... May also consider selling it at the right price ;)

Cheers mate.. I've tried to sign up to the US forum but they haven't sent me any replies to activate my account... Surely, there must be someone else who purchased the GS450h... or at least an RX400h to compare the MPG... The best average I've had was 28mpg around town in SNOW... (at 20mph)... Im not going to be doing that everytime I drive I'm afraid... Everytime I've been back to the dealers (Coventry Lexus), they seem to blame my right foot.... Currently Im tempted to trade her in for an E320 cdi the way things are going!! Even those who have test driven this car... Can you please give me your MPG figures :) Im planning to pay Lexus a visit in next few hours so any help appreciated!
