Hi, I'm hoping someone can help. I have read through similar posts but none seem to have the same symptoms. I have a 2010 F11 with rear suspension problems. Both air suspension bags have been changed and there is no drop in suspension height or leaking. Every morning, within the first mile, the suspension rapidly inflates and then deflates and feels like driving over a testing ground. I pull over, turn the ignition off for a few seconds, restart and everything is fine. When I finish work some 12 hours later, I have no faults and everything works perfectly. I have changed the solenoid for an Ebay £35 one but it made no difference. I have changed the relay but the new one causes the ride height error to show on the dash screen but feels normal, so I think it is causing the system to remain charged with air but isn't active. The fault remains there permanently at all times of day. I have now put the original relay back and the rocky road symptoms return in the morning but not evening's! Any ideas?
