I've got the dreaded air suspension inactive.I've recently been advised by a land rover mechanic to drill a hole in a small brass filter unit attached to the compressor but this did'nt solve the problem. So it got it checked diagnostically with another mechanic friend of mine and it came up with (excess energy rear offside) when i clear the error it works fine for a while then shuts down . Has anyone got any ideas. Im running L322 TD6 52 PLATE.
