Hi, i have a 2006 L322 TD6. I had an intermittant problem with the rear suspension dropping down overnight and the odd 'suspension fault' message. The message quickly went away and the car rised to the correct height. I have since taken it to a garage where they corrected some wiring around the car. NOW the problem is that the front drops and doesn't rise when started. Now there is no message, however on the manual controls for the air suspension the middle light and the top light are both constantly lit. When trying to raise the suspension the middle light flashes 3-4 times and then the same again. Could it be the compressor? Could it be faulty wiring? I would appreciate it if someone could point me in the right direction.

Some form of diagnostic kit will be a good place to start although allcomms wont work i don't believe, can you get any faults read ?
i have heard icarsoft mentioned a few times but not sure how good it is, faultmate is very good but expensive.
