Hi all,

I'm very interested in the hardware provided by Navik which supports Android and Iphone screen mirroring. They are based in USA and looking at some YouTube videos looks like an incredibly good upgrade. It is apparently easy to install too. 

My question is, has anyone on the forum used or seen this before?

The noise is still very much there and having gone over bushes to the best of my ability I can't seem to find the issue. 

I've always described the noise as a knocking, which is exactly what it sounds like on the move, however while investigating with the car stopped, it is almost like a deep squeak/friction type noise, very tricky to describe. When I rock the car on the spot I can feel where the noise is coming from, and it's coming from the black thing on top of the suspension mount, which I'm guessing is something to do with the sports suspension? I want to take this off to investigate but I want to be sure of what it is first. 

As always, help is appreciated.

Hi Rob,

I did, but for some reason it sent it in the quote I copied from you;

"Hi Rob. Thanks for the reply. Knocking is only present when moving, at slow and fast speeds, little variation in noise, however knocking is quicker when going over a bump, sounds like a quicker vibration. No difference when steering either direction.

Nothing obvious visually looking at usual suspects. Rocking the left side of car when stationary causes slight knocking, like checking for shock wear."

Mark, is the knock steady in pace, how quick, speed related variance, only knocks below or over certain speed, still knocks when stationary, knocking at all drive angles, ie straight ahead, turning one way or the other, only over bumps, going forward and back, does it get worse or better with greater steering angles, does it stay, go, get worse or better when braking and or sterring angle?

Hi all,

Apologies for my diagnosis being slightly vague but I have an issue with my GS450h with 105k which has an incessant knocking noise coming from the front left side of the car. My first thought was exhaust bracket, as the rattling sounds like metal on metal however the exhaust is fine, with no movement. My next guess would be something suspension related however it has recently passed an MOT with no advisories. It had been suggested to me by a local garage that it could be something on the top suspension mount causing the noise, as it sounds like it is coming from that area, however another garage said it might be the differential, however neither garage were willing to investigate further, saying it would be main dealer. Has anyone had a similar experience of noise and what it could be?

I can't confirm whether the noise stops or not when the engine kicks in. It sounds like it is coming from the driver's side of the engine. I can hear it well listening from the off side front wheel. The noise happens regardless of climate on or off.

Thanks Colin.

Hi again.

A couple of months ago I met up with a very friendly and knowledgeable member on here, Giles. He noticed a noise on my car when driving on Battery which sounds like a clicking/relay electrical noise. Does anyone have any experience with this or know what this might be?

Hi everyone.

I bought my Lexus in February and so far have put 6k trouble free miles on it. I purchased the car with quite patchy service history so whilst I am keen to look after it well, I don't have the dilemma of keeping up Lexus servicing just to keep a fully stamped book!

I know it is easy to say that it should be serviced once a year or every 10k miles, but other than engine oil, filter, are there any real necessities that need looking at/adjusting on a service? The cynic in me thinks that there aren't a whole lot of things that need that much attention and even. I don't want to sound wreckless, but I don't want to pay c. £250 for servicing for "peace of mind" when a simple engine oil and filter change every 8k-10k miles would suffice. Obviously I wouldn't neglect changing the other oils and coolants when they are needed but they are generally quite infrequently changed anyway.

I would appreciate opinions from other people on here and how you go about maintaining your pride and joy.

That's interesting Giles, thanks. I do have a Bluetooth OBD plug in adapter but I was after something that was capable of resetting my steering angle sensor. Is either piece of software you use capable of doing that?

Does anyone know whether there are any differences between a US, Jap or UK Lexus GS450H? Reason I am asking is because I am looking at buying a diagnostic tool and it lists US and Japan Lexus GS450H but not UK.

Any help would be appreciated.

Does anyone have any experience either getting this done or owning a diagnostic tool capable of doing this on a GS450H? I would be happy buying a tool that was capable of doing it, providing it wasn't ££££'s. I am almost certain mine needs resetting however there are no wheel alignment places near me (Stafford) which seem to do it.

Thanks Giles, those pictures are perfect. You're right about the picture I supplied being from an RX, I assumed they were the same part as the GS.

I had visions of buying a used hybrid transmission oil pump, reconditioning it and having it ready to swap straight over should it go wrong however they look rare as hen's teeth. I think I will just chance it instead. Thanks again for the pictures.

Hi Giles,

Although (thankfully) this problem hasn't affected me, I was hoping to get well prepped for if it ever did happen. Your description is fabulous and goes into great detail but as I have never seen a hybrid transmission oil pump, I wondered if you had a picture of the pump off the car so I would know what part to replace?

If this link works, this is what I think it is, but I'm not so sure;

Hi everyone,

I am the proud owner of a 2007 facelift Lexus GS450h. Having got to know the model quite well through my dad who also owns one, I am pleased to have purchased one myself. I just have a few questions;

I purchased the car with some patchy service history, which was reflected in the price I paid for it. The car has 82,000 miles on it. It has had a recent service in the past 2,000 miles so the oil is in good shape. My opinion is that it probably has been serviced however the service history has gone missing for around 25,000-30,000 miles. It is a one owner from new car. Let's assume that it did miss 3 services, would there be anything sensible I should do at this stage to keep it in good condition? I was thinking I won't leave it long until the next service, perhaps another 4-5,000 miles so the oil put in at 80,000 will not be in too long to give the engine a good clean out. I have no problem going to an independent dealer, but any advice is appreciated. Clearly it doesn't have a cambelt otherwise replacing that would be my first port of call.

My next question, has anyone had a roof box installed and could give me some rough figures as to what it might cost? The boot isn't exactly spacious so having a young family I think it would be a sensible choice to look at investing in one.

Other than that, what an enjoyable few hundred miles I have experienced so far. On a run I comfortably get 40+mpg and my daily commute returns 33-35mpg, which I am delighted with! Radar cruise control is something I will never get bored with too.

Thanks,

Mark

And I have just realised I am not in the GS forum! I'll repost this in the correct forum!
