Yes I have given that some thought. The only parts needed are the 4 coil springs and 4 shock absorbers? Is that correct? I am having difficulty getting prices on these parts. I can only find a company called Arnott who sell them. Will contact them on Monday.

In a ideal world I would not want to dispose of the car. Compressor £1922 from Lexus - part only. I have seen them on sale £680 on eBay. However need to know exactly what's wrong before splashing the cash which is why I am seeking guidance 😀

Thanks for info. I suspect you need tutorial in how to use it. It may be beyond my competence. Will probably need to take to a independent who knows their stuff before I decide whether the car is going to the graveyard. Anyone know of any reputable independent in Birmingham/West Midlands?

It looked like the above. The mechanic said there is no air leak. He did not look at the struts etc on a ramp. Not sure how correct the info given is. I have started looking at other cars which is a bad sign....

Thanks Chris. Tried the above procedure with disconnecting the battery. I did not hear the compressor, but then again are you supposed to? Prior the suspension failing I was able to hear the compressor whirring away. At times it sounded pretty manic, maybe that was a sign that I ignored. I looked at each strut, both the fronts did not move at all. The rear may have moved marginally but to be honest I am not 100% convinced. I'l try and chase up what the machine name is. Unless it is obvious from the attachment (pardon my ignorance). Is there anyone in Birmingham with Techstream other than dealers? Not sure where to go from here....

Thank you for your detailed response Chris. Will try tomorrow and will post how i get on. Have had to drive car on short journeys without suspension active. Unpleasant to say the least. Hope that has not done too much harm?

Hello all, First post. Would be grateful for you opinions. I have had a look at the previous posts on air suspension problems and they have been useful. I know that the air suspension system is complicated and people may not be able to give specific advice, but any advice is helpful. My 56 plate RX350 has 200,000 on the clock. I had all 4 height sensors replaced in 2014 at 156,000 at the dealers. Recently the off light on the air suspension came on temporarily and then disappeared. Following day all 4 corners of the car were lowered. The compressor makes no noise at all. The air suspension light moves from N to H but there is no change in the suspension. The ride of course is terrible. The 2 fault codes showed C1742 (compressor motor) and C1751 (continuous current to compressor motor) at a independent garage. The garage told me its either the "relay" or "compressor". Not sure which relay they specifically meant. Not keen to take car to dealers as any repair cost by them would be worth the cost of the car. Keen to keep the car. Anyone have any advice on best course of action? Thanks in advance Kind Regards John
