What VSR Can Repair and Why Repairing Your Original Module Can Make Sense
Modern vehicles rely on dozens of electronic control modules to keep the vehicle running, communicate with each other and control everything from the engine and braking system to the dashboard, airbags, immobiliser and body electronics.
When one of these modules develops a fault, replacing it isn't always the only option.
At VSR, we specialise in the repair of selected automotive electronic modules and instrument clusters, helping customers avoid unnecessary replacement costs and get their original vehicle electronics working again.
Common symptoms of a faulty vehicle module
Electronic module failures don't always present themselves in the same way.
Depending on the module and the type of failure, you may experience:
- No communication with a control module
- Warning lights appearing on the dashboard
- Intermittent electrical faults
- Instrument cluster going blank
- Gauges stopping working
- Vehicle failing to start
- Airbag warning lights
- ABS or ESP warning lights
- Loss of communication with diagnostic equipment
- Multiple CAN communication fault codes
- Functions working intermittently
- A module appearing completely dead
A diagnostic fault code doesn't necessarily mean that the module itself needs replacing.
The underlying problem could be a power supply, communication circuit, damaged component, failed electronic component, cracked solder joint or another internal PCB fault.
This is where specialist electronic diagnosis can make a difference.
Why repair the original module?
There are several reasons why repairing an existing module can make sense.
1. It can be cheaper than replacement
A new manufacturer-supplied module can be expensive, particularly when programming, coding or configuration is also required.
A successful repair of the original unit can provide a much more cost-effective alternative.
2. You keep your original module
Repairing the existing module means you don't necessarily have to replace it with another used unit of unknown history.
3. Avoid unnecessary programming
Some replacement modules require coding, configuration or programming to the vehicle.
Keeping the original module can avoid some of these complications, depending on the type of repair.
4. Known faults can be repaired efficiently
When a particular module has a known failure pattern, a specialist repair can be much more straightforward than replacing parts unnecessarily.
What does component-level repair mean?
Component-level repair means that we don't simply replace the complete module.
Instead, the module is opened and inspected at circuit-board level.
Depending on the fault, this can involve checking:
- Power supply circuits
- Voltage regulators
- Communication circuits
- CAN bus interfaces
- Components and semiconductors
- Solder joints
- Connectors
- PCB tracks
- Memory devices
- Microcontroller-related circuits
- Other electronic components
The exact repair depends entirely on the module and the failure.
Some faults can be repaired relatively quickly, while others require more extensive diagnosis.
Our postal module repair service
VSR provides a UK-wide postal repair service for selected automotive electronic modules.
The process is straightforward:
1. Contact VSR
Purchase the advert for the repair you require on our website. If you can't find this you can tell us the vehicle details, module part number and symptoms you're experiencing.
2. Send the module to us
Once you have purchased the service on our website or once we've confirmed that the repair is something we can investigate, the module can be sent to our workshop.
3. Testing
The repaired module is tested using the available bench-testing equipment and appropriate test procedures.
4. Return
Once the repair has been completed and post tested, the module is securely returned to you using a tracked 24hour courier.
We aim to complete all repairs within 1-2 days after receiving the item.
