Service FAQ.
Should a module be replaced because it stores a fault code?+
Not automatically. A module can report faults caused by wiring, voltage, communication or another component. Its supporting circuits should be checked first.
Can you fit and code a replacement module?+
For supported vehicles and modules, replacement setup may include programming, coding, security matching or adaptations.
Can every damaged module be repaired?+
No. Repairability depends on the module, failure and available specialist support. Diagnosis helps establish the realistic options.
