Hey guys. So after reading its kinda scaring me as I have symptoms thats seem to be related to the active suspension control module.

1) Car will only raise and lower 1/2-3/4 of an inch
2) Doesnt seem to be huge difference between sport and comfort setting
3) Cant make any corner of the car dip a little by pushing down on it, thats turned off
4) It seems stiff on bumps and you can feel them
5) car sits a little lower in rear

My mechanic doesnt have a techstream but some other expensive system like it but I was going to have him scan if for the active suspension control module being faulty. I have no dash lights on either.
Being buried under the dash brings back memories of heater cores. But if it is Im not sure I will keep the car as labor is so much and Id be putting a used ebay one in.

 

My 13 will only raise to 29 inches thru the centre of the wheel to the bottom of the wheel well, you can make it lower a small amount from stock with the links.
There isn't a huge difference in the comfort modes there.
Ya, you cant bounce the car if ignition is on or off.
speedbumps can be rough but mine is abit lowered
MckellyB said in his post about lowering that pre 2013 460's look like they have a couple of bags of concrete in the trunk so that might be normal for your car.

 

Cool thanks, yet more inherent issues with the ls460, but good to know its normal. I was thinking of adjusting my rear height sensors to see if it might be the issue. Those dont raise or lower at all I think. But them not functioning could create a hard ride?

 

Just to chime in my personal exp with my '11. Sports / normal / comfort - difference is huge. It's supposed to be. Yes, it doesn't rise as much as other cars in HEIGHT HI position.
Techstream will tell if you have a funky sensor or other issue.
