Specific module repairs
Clients can mail in parts for these repairs. Please contact us with your vehicle details and the part you need repaired before sending it, so we can confirm the work and provide mailing instructions.
- BMW FRM repairs The footwell module (FRM) controls functions such as lighting and electric windows. Faults can cause lights, indicators or windows to stop working, or prevent communication with the module. We assess the module to confirm suitable repair options.
- Jaguar XF BCM repairsThe Body Control Module (BCM) manages functions such as central locking, lighting and other body electronics. Faults can cause intermittent electrical problems, communication errors or starting issues. We assess the module and confirm whether a repair is suitable.
- Mercedes-Benz ESL repairs The electronic steering lock (ESL) forms part of the vehicle’s start-authorisation system. A fault can leave the steering locked or prevent the ignition and engine from starting, even when the key is recognised. We assess the lock and confirm repair options for your model.
- Electronic steering wheel lock repairsAn electronic steering lock secures the steering when the vehicle is switched off and releases it when starting is authorised. Faults can cause steering-lock warnings, failure to unlock or intermittent no-start issues. Repair availability depends on the vehicle and lock type.

KEY, ECU &
MODULE QUESTIONS.
Can you code a car key?
Car key coding and programming are core services. Send us your vehicle make, model and year so we can confirm the key work your car needs.
Can you code or program a replacement ECU?
We work on ECU coding and programming, including replacement ECU setup for compatible vehicles. Share your vehicle details so we can confirm the requirements.
What does Cardoc Diagnostics specialise in?
Our main focus is car key coding and ECU coding and programming, with crash data resets and electronic module work. General diagnostics are not our primary service.
Which vehicles do you work on?
We support a range of European, Japanese, Korean and other makes. Send your make, model, year and required coding service to confirm compatibility before booking.
What are the symptoms of BMW FRM failure?
A faulty BMW footwell module (FRM) can cause lights, indicators or electric windows to stop working, or prevent communication with the module. These symptoms can also have other causes, so the module needs assessment before a repair is recommended.
What are the symptoms of Jaguar XF BCM failure?
A faulty Jaguar XF Body Control Module (BCM) can cause central-locking or lighting problems, intermittent electrical faults, communication errors or starting issues. These symptoms do not confirm BCM failure on their own. Contact Cardoc Diagnostics with your vehicle details and symptoms so we can confirm suitable next steps.
Can a Mercedes-Benz ESL fault prevent the car from starting?
Yes. A fault in the Mercedes-Benz electronic steering lock (ESL) can leave the steering locked or prevent ignition and starting, even when the key is recognised. Other faults can produce similar symptoms. We assess the lock and confirm repair options for your model.
Can I have my Mercedes Benz EIS ignition module replaced?
EIS (electronic ignition switch) replacement may be possible, depending on your Mercedes-Benz model and the fault. Contact Cardoc Diagnostics with your vehicle model, year and symptoms so we can confirm compatibility, replacement options and any coding or programming requirements before arranging the work.
Can an electronic steering wheel lock be repaired?
Repair may be possible, depending on the vehicle, lock type and fault. Common symptoms include steering-lock warnings, failure to unlock and intermittent no-start issues. Send your vehicle make, model, year and symptoms to Cardoc Diagnostics so we can confirm compatibility and suitable repair options.
Can I courier a module to Cardoc Diagnostics for repair?
Yes. Clients can mail in parts for the listed specific module repairs and compatible airbag modules for crash data resets. Contact Cardoc Diagnostics with your vehicle details and the part needing repair before sending it. We will confirm whether the work is supported and provide mailing instructions.
