Specialist supportPostal ECU cloning starts with original and donor module identification
Our postal module service enables customers and automotive businesses to send supported ECU, TCU, BCM, BSI, SRS and other electronic control units for controlled bench work. Compatibility is confirmed before shipping, and international customers are responsible for secure packaging, customs declarations and carriage.
For a cloning enquiry, photograph the original and replacement labels separately and explain any previous programming attempts. A donor that looks identical may still have different hardware or software. We check the available original data and proposed replacement before recommending a postal booking.

When this service may help
When to send an ECU, TCU, BCM or airbag module by post
01ECU or TCU requires cloning or recovery
Send clear photographs of both controllers and their labels before shipping. We compare part numbers, hardware, software and memory type to confirm whether cloning, data transfer or recovery is technically suitable.
02Airbag controller contains supported crash data
After the vehicle’s physical restraint components have been repaired, supported SRS modules can be assessed for stored crash data, internal faults and coding requirements before a postal reset is accepted.
03Module requires specialist bench programming
ECU, TCU, BCM, BSI and selected immobiliser modules may require controlled bench or boot access when in-vehicle communication is unavailable. Compatibility is confirmed before the unit is posted.
England • Scotland • Wales • Northern IrelandPostal ECU programming across the United Kingdom
Our UK postal ECU cloning and module programming service enables vehicle owners and independent garages to send approved engine ECUs, gearbox TCUs, BCMs, BSIs, SRS units and selected security modules to our Stourbridge workshop for assessment. For ECU or TCU cloning by post, send clear labels for the original and replacement units before shipping; some jobs require both modules. The service depends on the exact hardware and available data, and not every module can be cloned or repaired.
UK Mercedes ECU example: Our Mercedes W210 ME2.8 ECU cloning and Stage 2 remap by post case study shows the photographed bench setup and module labels.
For ECU cloning and replacement programming, ask whether both the original and donor are required. For BSI and BCM cloning, include body-electronics symptoms and both labels. For airbag crash data reset, provide the SRS reference and fault report. Failed programming or a non-communicating unit should be assessed through our bricked ECU recovery service.
Quotes, turnaround and return carriage are confirmed for the individual job. Pack only the approved modules securely and use a suitable tracked service. Read our UK module postage guide before shipping, and review the service terms and conditions.
