Hi Steve,

You can download the Diagnostic Trouble Code Summaries at this link:

Jaguar X350 DTC Summaries

C1424 indicates an open circuit in the front left shock adaptive damping actuator, which could be as simple as the ECATS solenoid connector is loose or disconnected from the top of the air spring/damper unit you just installed.

The manual does not list C1429, but the code for the same problem at the front right shock is C1419 - could that be your other code?

Cheers,

Don

Haven't read the entire thread, so forgive me if this is repeated information.
Worth checking the release valve on the compressor, this can sometimes get clogged with gunk.
A new (recon) ASM solved just about all my suspension issues, very cheap fix.
