2006 C6 A6 4.2 - convert adaptive air suspension to coil over

Has anybody converted the A6 adaptive air suspension to standard coil over?

Mechanically probably not an issue, but what about codes (suspension code may also influence ABS, active cruise controls, ESP, height adjustable headlights, etc.)?



Air suspension is just creating too many problems (replace one strut already at $1k, compressor rebuild, relays changed twice, valve block changed, etc.).
