geoffbeaumont Posted February 25, 2019 Share Posted February 25, 2019 Does it still go down if you inhibit the EAS from the dash or by leaving the upper tailgate open? That should stop the controller opening and closing valves, so if it still goes down then you've narrowed the cause to a leak. Assuming that, the next step is to find the leak. In theory for both front and back to go down you'd need to have at least two leaks, but I guess you may find only one does this when the system is inhibited and can't try to level things up. A handheld plant sprayer with water and washing up liquid is your friend. Give the air springs and air lines a good soaking and look for bubbles. Where the plastic lines cross above the exhaust is worthy of close attention - if the exhaust has every corroded through there (even in the past) they can be melted and fail later. The actual valves in the valve block leaking is also possible. Bit harder to prove, but they can be DIY rebuilt (everything on the P38 EAS can be DIY'd - it's not nearly as scary as some people make out). Do you have any fault codes from the EAS system?
