Amplifier and Module Repair
OEM Amplifier & Electronic Module Diagnostics & Repair.
We diagnose and repair OEM amplifiers and electronic modules from modern vehicles. You can book the complete vehicle into our workshop, or send an eligible unit to us using our postal repair service.
On-vehicle diagnostics first.
For workshop bookings, we test the system in the vehicle first. If the amplifier or module is confirmed as the fault, we remove it carefully and continue with bench testing and repair.
UK & International postal repair.
For postal repairs, you can send an eligible amplifier or module directly to our workshop for bench testing and repair.
Postal repair services apply only to the repair and testing of the amplifier or electronic module itself. Any vehicle-side diagnostics, fault tracing, coding, programming, configuration, communication faults or additional work required on the vehicle are not included within the postal repair service.
Repair before replace.
We test down to component level, confirm the fault and repair only what the evidence supports. Professional bench equipment and hands-on electronic repair experience guide each step.
Component Level Repair
We can work down to individual components, which may avoid the cost of replacing the complete module.
Coding & Programming
Post-repair coding, adaptation and programming as required.
Water Damage Solutions
Cleanroom-style processes to recover flood-damaged modules.
Cost-Effective Alternative
A fraction of the cost of a brand-new dealer module.

Tested properly, not guessed.
We provide both UK and INTERNATIONAL postal repair services for selected amplifiers and electronic modules. Typical turnaround time for postal amplifier and module repairs is approximately 3–5 working days under normal operating conditions. Some repairs may require additional time depending on fault complexity, testing requirements, internal damage or parts availability.
Intermittent faults, communication issues and water damage can take longer to prove. In these cases, we test in stages and allow enough time to confirm the underlying fault.
Our aim is to find the actual cause and repair the unit at component level where it is sensible to do so, instead of automatically replacing the whole assembly.
Each repair is supported by professional test equipment, electronic laboratory tools and experience with modern vehicle networks.
Verified before it leaves us.
Every repaired amplifier or module is tested under load before it is returned, so the result is verified rather than assumed.
Clear updates from start to finish.
For work on the vehicle, book a workshop appointment online and tell us what the vehicle is doing.
For postal repairs, use the Online Repair Request form to tell us about the unit and the symptoms before sending it in.
We keep you updated on what we find, whether the unit is repairable, the likely cost and the final test result.
Every repair is completed in our specialist workshop, tested carefully and checked for reliable operation before it leaves us.
