Re: self leveling troubleshoot (archive)

Sounds like the accumulators. They're what keeps the pressure close to constant. Easy check is to open one up & see how much fluid it dumps. Normal is just a few ounces. Bad is around a quart. Fix is to replace the accumulators, which are mounted in the wheel wells. They run about $100-150 a piece; shop around. Check the BCG for more info on troubleshooting. Be sure to check the lid of the resevoir (under the spare) for a sticker which shows which type of Pentosin hydraulic fluid to use --- there are two types. Good luck! ---JT

Hope someone has had this... car goes on about a 30 second cycle, first dumping pressure (sags about 4in) then pumping up to normal, holds for a short while and repeats. I've disconnected the pump, and it seems to hold whatever ride height you disconnect at. I'd probably go for acumulators, but if it's into the high dollar items I'd just as soon delete the system. (which in turn would lead to new springs all around and Bilsteins). Currently everything is as delivered but with 140k on it.
