The ECU shouldn't lose its immobiliser programming by just disconnecting the battery.

Have you looked on ebay.com? Search for bushing rather than bushes.

It's worth checking the earth connections are clean and tight but I think everything is normal. An alternator will produce 14v at idle if the battery requires charging but when you turn on headlights etc. you start to draw more amps than the alternator can generate at idle speed so the voltage will drop. Above 2000 rpm and the voltage should rise. Only if the voltage drops below 12v (really 12.4) do you have a problem. What size battery did you install?

congrats and welcome to LOC :)

That site gives details for US vehicles. The wiring colours and pinout will be the same for the UK vehicles just need to remember that locations may be different between LHD and RHD.

Have you tried another disc first? Replacing the laser unit shouldn't affect the working of the main unit provided you don't damage it during your attempted repair. The new laser unit should be identical to the old one, if when you open it up you find it isn't then don't try and replace it.

What is the cost of a new vehicle in country? It may well be more than the UK which could explain the higher used cost.

If you are using 93GB per month then you may well fall outside of most providers fair use policy, unrestricted or not. I've heard good things about Zen for business /high domestic users.

The windscreen is bonded and needs to be left to set for a few hours. Failure to do this will produce wind noise. You need to take it to somebody that knows what they are doing but it doesn't have to be a main dealer. My local Lexus dealer just sends them to a specialist anyway. MOTs are fixed price. A main dealer cannot charge more than the price fixed by the government. Service costs are around £150 for minor and £250-350 for major depending what needs doing. Only when plugs or cambelt need replacing do the service cost go very high.

It's not uncommon for Lexus to have yearly updates. They are minor changes like a new exterior colour option. It's also more common on new models as things are improved. The SC430 had suspension changes in the 1st and 2nd year of production in an attempt to improve ride quality.

That's 7 more years than they give for the 430 engine, they must be confident of its reliability. I suppose with the stress shared by two types of propulsion, it provides an easier mechanical life. bill I think it is more to reassure customers of the hybrid system. I can see them having to replace quite a few batteries in the warranty period. The car is probably priced to include another set of batteries.

Hello, welcome to LOC You may also wish to join the US site: http://us.lexusownersclub.com/forums/index.php

Does your average mpg go down when you are at a stand still? I don't believe it does and therefore it is taking it into account. When I have to wait in traffic in my non-hybrid vehicle the average goes down and down. It's just your instant mpg figure that isn't accurate.

If you're just passing through I guess you won't see the replies but hello anyway :)

I would imagine the same brakes are used across the IS range, including other countries. If that is the case they can handle the IS350 which has over 300bhp. I know about the performance enhancement of the 220d (should be around 220 HP and 0-60 mph in 7.5 sec which is even better than the second gen IS300) , but I have not heard anything regarding the 250. Could you tell us more about this? Here is the answer I got from TTE last week: We have a performance kit for the 177PS D4D models under development and try to introduce it within this year. Unfortunately we do not have any datas for you so far. I would imagine if they are going to do anything with the IS250 it will be a turbo/SC add-on. Very little can be gained by tuning a NA engine.

it may be worth cleaning the throttle body. Also try posting on the US forums - many more LS owners on there than in the UK: http://us.lexusownersclub.com/forums/index.php

What model/year vehicle do you have. There may be two fuse boxes, did you look in both footwells?

There are currently 7 GS430 all at £30k and another 10 below £35 at Lexus dealers. They all seem to be old demonstrators. Now that is a great price however I cannot help but think they will be selling for £20k next year so there are still big losses to be made if you purchase one now. On the hybrid warranty issue, Lexus give a 10 year/100k warranty in the US so they must be confident it will be reliable.

I had a look on the Lexus web site last night, I cannot believe how much 430s have lost in value in 12 months. A 12 month old £47k vehicle is selling at a main dealer for £30k, trade in value must be around £26-27k. I imagine the 450h will hold its value better.

A caliper kit won't help this noise. It's not the rubber seals that have worn.

Hi I would post your question on the US forums. The ES isn't sold in the UK and the few imports that are in this country may be different to the US models. http://us.lexusownersclub.com/forums/index.php

There are 3 sensors not just the one you can see. The 2nd one is not easy to get to being on the other half of the V near the bulkhead. The first two sensors are also Denso air/fuel ratio sensors rather than just normal oxygen sensors so don't just buy a generic sensor, it won't work. Also if you purchase a generic sensor you will probably have to splice the wiring into the old connector. The error code produced will tell you which sensor needs replacing and also what is wrong, e.g. heater faulty, no output, etc. You can clean them but it normally doesn't make too much difference. To clean them you need to burn off any deposits gently using a blow torch. For normal sensors they are easy to test by making the mixture lean/rich and monitoring the sensor output on an oscilloscope or some ODB-II readers.

well the bigger wheels aren't a problem now bought some 18's today oops is that £50 a caliper It's not the rim size, UK Supra wheels are 17". The 4-pot brakes stick out a long way so not many 3rd party wheels fit a UK Supra without spacers. The standard wheel spokes only run 2 or 3mm away from the calipers and they are angled to draw air into the brakes for cooling. As for stoping the noise of your existing calipers you can try removing the sliding pin and packing it with grease. It that doesn't fit it there isn't anything you can do its just wear and not dangerous.

Welcome back :) How was the Z?

yes I would get the fluid replaced as it would have absorbed water which can lead to poor braking performance and also rust the brake lines.
