Important Installation Warning:

• Programming Required: This module is NOT plug-and-play.

Installing it without programming may result in "Start Countdown" warnings or the vehicle not recognizing the module.

 The "Connector Check"

These modules often fail because AdBlue fluid leaks into the wiring harness and "wicks" up into the computer plug, causing corrosion.
