When I fitted mine they were silly low [the wheels hardly went round in the arches] I took it for test drive and although it rubbed just about everywhere none of the lights you mention came on?

This may sound stupid but have you connected the wires up properly or have they come apart?

On some coilovers you may have to move the wires about due to where the mounting brackets for the wires are mounted.
 
Yeah thats because with the car being lower the wires are to long so they need modifying so they don't catch......Think we just used cable ties on the slack when we did mine.
 
To be honest I'm not sure.....can they not just cut and join the wires?

Or do they not just unclip somewhere in the loom so they can be replaced?
 
Do they look like this?

with the spring and moutning cup (at the bottom) in hands, (i.e. not on the car) if you put them together, the mounting cup would slot in with alot of ease if that makes sense at all. I wasnt sure if it would need pushing into the spring and it would be a tight enough fit that it would stay in... on mine it wasnt tight at all, but the opposite end was!
