Hi all,
I have recently fitted some new Bilstein rear air suspension bags to my S211, as the NS was starting to drop occasionally when left for many days. Fitting of the new bags went smoothly, though I cannot get the compressor to start running to pressurise the system prior to lowering it onto its wheels. The car (on axle stands) of course thinks it is too high as the suspension is fully extended, so I assume the compressor only kicks in when the car is low - I don't want to lower the car until there is at least some pressure in the bags.
All the online advice (and Bilstein's instructions) suggests I need Star to do this. I have iCarSoft CR Pro but that can just read some suspension data, it cannot command anything.
Anyone got any experience of getting round this? I am tempted to unplug the compressor from the loom, and simply feed it 12V from another battery.
Thanks for any advice anyone can offer,
Martin.
