Photograph the condition before changing it
Record where the water was found, whether connectors were wet and how the symptoms developed. Photograph the exterior, labels and connector condition before cleaning or dismantling removes evidence.
Tell us if the vehicle was powered while wet, if the ECU has already been opened or if someone attempted repair. Avoid improvised drying, scraping or powering a loose controller. The assessment needs to account for both visible condition and internal damage.
The ECU may be only part of the affected area
The installer should establish whether the loom, connectors, mounting area or other modules were affected. Refitting a repaired or replacement ECU into a wet housing or damaged connector can leave the original cause unresolved.
A controller can appear externally clean while the connected vehicle still has supply or network problems. Equally, severe-looking corrosion does not tell us remotely which original data can be recovered. Send the vehicle-side findings alongside the photographs.
Choose repair or a replacement-data assessment
Repair suitability depends on the affected circuitry and condition. When a repair is impractical, supported recovery of original information and transfer into a compatible donor may be considered.
Keep the original unit and contact us before ordering a replacement. An accepted assessment may establish a route, but recoverable data and donor suitability are separate questions. Some damaged units cannot support either repair or a usable clone.
Coordinate shipping and refitting
Agree how the unit should be prepared and packed before dispatch. Do not post wet components or a fluid-containing assembly without the specific handling instructions for the job.
The return plan should include correction of the leak, inspection of affected wiring and any required coding or adaptation. Include your postcode, who is carrying out that work and whether the vehicle is currently immobilised.
