Classic EAS

hi I'm having problems with my air suspension , takes time to rise when I start up goes down quickly after I leave it .
Compressor is noisey but when I use the lower and higher settings goes up and down no problem
Spoke to a guy on eBay who refurbishes pump , was wondering if there's anything else to check.
Suggestions welcome!!

Could be a leaky valve block....sounds like air is leaking from the tank if it takes a while to rise....if the pump is noisey, best get it changed/refurbed....that could be the source of the issues....no air, no worky!

Ok thanks I take it I have to use the switch under drivers seat to lock out suspension before removal?

Yes, it will halt all automatic levelling and prevent the compressor running.

Ok thanks for that off at weekend will have a go getting it off

Support chassis on stands before sliding underneath......better safe then sorry!
