FAQ
Can I post my ECU or module to you?
Yes for selected modules. Contact us with the module type, symptoms and vehicle details. We provide packing guidance and assess suitability before you send anything.
Do you repair BMW FRM modules?
We repair common BMW and Mini FRM footwell module faults including lighting and window issues. See our completed jobs for examples of module work.
Can data be transferred to a replacement ECU?
For some compatible modules, data can be transferred from the original unit to a suitable replacement for legitimate repair purposes. Availability depends on module condition, vehicle platform and technical support.
What types of vehicle work do you refuse?
We focus on legitimate repair, cloning and coding for fault-related module issues. Proof of ownership is required where relevant, and we may decline work we cannot verify or support.
What proof of ownership do you need?
For security-related work we verify vehicle identity and customer identity where required — typically the V5 registration document, a legible VIN and valid photo ID. We may request additional evidence for fleet, lease or rental vehicles.
Do you publish security PINs or bypass methods?
No. We never publish PINs, security data, dumps or bypass procedures.
Do you provide security bypasses or emissions-delete services?
No. We do not offer unauthorised security bypasses, odometer alteration or defeat services for DPF, EGR, AdBlue or other emissions-control systems.
