Hmm, you certainly got a bargain! How is the front section of the exhaust? It was blowing between the o2 sensors on the Y pipe when I owned the car. Glad it's mot'd and back on the road, enjoy.

No It doesn't.

Sunroof frame is rusted on mine too, and o/s rear window cloudy. Luckily the w/bone bushes have been replaced and the wheels look suspiciously clean so I'd say they have already been refurbished too.

Still all good on the suspension front, I may as well move on to the next issue, there is quite a list. Steering wheel doesn't move. Sat nav dvd player. Rear shelf sub woofer. Exterior lock button on the drivers door. Front parking sensor. O/S headlight squirtie. A/C leak. Maybe a very slight leak from one of the exhaust manifolds, only noticeable from outside the car. I'll probably look at the steering wheel first, if it were your car what order would you tackle the jobs in?

I managed to track down the business selling the part on eBay and yesterday, around 3 pm, paid cash straight into his bank. Fairplay to the bloke the parcel was waiting for me when I finished work today at 2 pm. I've fitted it and, so far, the car hasn't lost any height. https://drive.google.com/file/d/1WxABAbPancsblOZrJBmnHt75kjxFhLgv/view?usp=drivesdk

So I went ahead and replaced the valve module and, fingers crossed, it seems to have solved the problem. https://drive.google.com/file/d/1WxABAbPancsblOZrJBmnHt75kjxFhLgv/view?usp=drivesdk

No longer required as I've just purchased the one linked to above, I did pop into my local main dealer but they wanted over £500 instead of the £274.88 I've just paid. Fingers crossed, A, that it turns up and B, that it fixes the suspension issue...

Yep, and today after closer inspection I have found this part to be leaking from the plastic housing, caused by it's metal bracket corroding. The shock is a sealed unit filled with oil, there maybe some electrical magic added to adjust the firmness. The 'spring' is the airbag which is controlled by the valves I linked to above, they are mounted externally and adjust the amount of pressure in each bag accordingly.

I've just had a closer look at the rear distribution valve and it is leaking very slightly, from where the plastic is in contact with the (corroding) metal bracket. They have the part on fleabay but I don't really want to spend almost £300 just to then uncover another issue with the suspension... https://www.ebay.co.uk/itm/New-Lexus-LS430-Air-Suspension-Rear-Valve-Block-Height-Control-No-2-4809650040/203335283824?epid=1713774933&hash=item2f57ba3470:g:0yMAAOSwXXpgaL3O

I'm looking for a good used part rather than new, just incase there are other issues... https://www.ebay.co.uk/itm/New-Lexus-LS430-Air-Suspension-Rear-Valve-Block-Height-Control-No-2-4809650040/203335283824?epid=1713774933&hash=item2f57ba3470:g:0yMAAOSwXXpgaL3O

As I mentioned above, there is a unit under the rear of the car, near the diff. This has two valves on it that, I guess, control the amount of air going to the struts. https://www.ebay.co.uk/itm/New-Lexus-LS430-Air-Suspension-Rear-Valve-Block-Height-Control-No-2-4809650040/203335283824?epid=1713774933&hash=item2f57ba3470:g:0yMAAOSwXXpgaL3O Edit:- Just found the unit online.

I think you are confusing what tracking is.

I've been looking at BC coilovers for £787.55 but don't want to ruin the ride, I would rather try and find where ever the leak is coming from and keep the car standard. https://www.driftworks.com/bc-coilovers-for-lexus-ls430-00-07.html?gclid=Cj0KCQjwsLWDBhCmARIsAPSL3_3GOLwx7fPPhxfUBg9L9KfyVGUiPd9ABUvKJflrtK_9owGsqYkCObIaAt1UEALw_wcB

I'm not meaning to be rude, just curious! I'll be 45 next month.

Hmmm, me too. Is there a maximum size? I've looked for a 'faq' area on the site but to no avail...
