• if you start car and use rocker switch, suspension comes up fine.
• if you just drive off and allow auto level, front takes forever to come up, but not as in slow raise, can take 2-3 mins then will just shoot up (usually when stopped)
• when driving front consistently drops down for a while and then returns (slowly)
• pump is almost constantly running, has a 10-20 second break max every few minutes.
• pump is hot to the touch also.
• some days car rides smooth as silk, some days rides like a go kart.

ok so im new to EAS. my P38 has some suspension issues. ill break them down:

• if you start car and use rocker switch, suspension comes up fine.
• if you just drive off and allow auto level, front takes forever to come up, but not as in slow raise, can take 2-3 mins then will just shoot up (usually when stopped) - As the car moves the Suspension physicaly moves to the undulations in the road, as the car is trying to raise to a set point as indicated by the height sensor, but the height sensor reading keeps changing (due to the road bumps) it can take a while until it finds a stable reading.
• when driving front consistently drops down for a while and then returns (slowly) - The EAS is trying to fight a leak I suspect in the Front Bags
• pump is almost constantly running, has a 10-20 second break max every few minutes. - Do the Wammers Pump check as Stufer Mentions - I suspect a Leak somewhere and the poor little pump is struggling to keep up with the pressure loss
• pump is hot to the touch also. - As above
• some days car rides smooth as silk, some days rides like a go kart. - As Above

im ready and have my bottle of leak detector, but can anyone offer some pointers based on the faults ive listed? i have an idea of how the system works, but advice would be appreciated.

right, thanks for the help. ill have a look over the weekend. when i bought the car it had receipts for genuine nags that were replaced 2 years ago but i do respect the fact that this means nothing and will check regardless.

one thing i forgot to mention as well, when suspension does come up, there is like a clunking through the travel, almost like trying to operate a dry pneumatic cylinder, moves eventually but with a juddery/non linear motion.
