How Module Repair Works

Diagnosis

We run a full diagnostic scan to identify the faulty module and confirm it's repairable. Free diagnostic with any repair booking.

Removal & Bench Test

The module is carefully removed and tested on our bench equipment to pinpoint the exact fault — water damage, blown capacitors, relay failure, etc.

Repair & Test

Our technician repairs the circuit board, replaces failed components, and thoroughly tests the module to ensure it meets manufacturer specifications.

Refit & Verify

The repaired module is refitted to your vehicle, coded if necessary, and road tested to confirm everything works perfectly.
