Ford BCM Body Control Module Cloning by Post — U0100 & U0155 Fixed
A U0100 or U0155 fault on a Ford means the vehicle's communication network has lost contact with a critical control unit — and in the majority of cases the culprit is the Body Control Module (BCM). What that looks like from the driver's seat is a dashboard that behaves strangely: warning lights that shouldn't be on, central locking that operates by itself, windows that stop responding, interior lighting that does whatever it pleases, or a car that simply won't start because the immobiliser can't verify its own configuration. The BCM has either developed corrupted firmware, suffered an internal component failure, or lost the programmed data that ties it to your specific vehicle.
The Vehicle Check has spent over a decade as a hands-on automotive electronics specialist — not a broker, not a parts-swapper — working across Ford, Volkswagen Group, Mercedes-Benz, BMW and more, bench-testing and cloning body control units, mechatronics and electronic modules every single working day. When it comes to Ford BCM cloning specifically, we've handled everything from ageing Mk2 Focuses to current Transit Customs and 2026 Fiestas, and we know exactly where these units fail, why, and what it takes to bring one back to factory configuration without touching your dealer network.
What Is Ford BCM Cloning — and Why Does Your Car Need It?
BCM cloning is the process of extracting every byte of data from your original Body Control Module — your VIN, security credentials, configured options, mileage records — and writing it precisely onto a tested replacement unit. The result is a module that your Ford recognises as its own from the first ignition cycle, with no mismatched keys, no immobiliser lockout and no dealer visit required to pair it to the car.
This is fundamentally different from buying a second-hand BCM off a breaker. A used unit carries another vehicle's entire identity. Fit it and you'll immediately generate new communication faults, key-not-recognised warnings and potentially a no-start condition that's harder to diagnose than the original fault. Cloning avoids every one of those pitfalls because the data moving into the new unit is yours — unchanged, verified and tested before it leaves our bench.
Which Ford Models and Fault Codes Does This Cover?
TVC's Ford BCM cloning service covers an extensive range of models and years. The units we most frequently work with include:
- Ford Fiesta (Mk6 through current 2026 models)
- Ford Focus (Mk2, Mk3, Mk4)
- Ford Mondeo (Mk4 and Mk5)
- Ford Transit and Transit Custom (V363 and beyond)
- Ford Transit Connect
- Ford Kuga (Mk2 and Mk3)
- Ford Galaxy and S-MAX (Mk2 and Mk3)
- Ford EcoSport and Puma
- Ford Ranger (T6 and T8 platforms)
The most common fault codes we see paired with BCM failure include U0100 (lost communication with ECM/PCM), U0155 (lost communication with instrument panel cluster), U0140, U0401 and various B-code body network faults. If your scan tool is reporting a CAN bus communication storm and the BCM is pointing at itself, that's exactly what we handle. Not sure if your code is covered? Call us on 0203 489 2610 and we'll tell you straight.
How Does the Mail-In Service Work?
The process is designed to be as straightforward as a car part postal service can possibly be. Here's exactly what happens from your driveway to your door:
- Contact us first. Call 0203 489 2610 or get in touch through our BCM, BSI & FRM service page so we can confirm your module reference and advise on anything specific to your model.
- Remove your BCM. On most Ford models the BCM sits in the passenger footwell behind a trim panel, or in the engine bay fuse/relay box depending on the generation. If you're unsure, your workshop manual or a quick call to us will point you in the right direction.
- Package it properly. Wrap the unit in bubble wrap — at least two full layers — and place it in a rigid cardboard box with additional padding material around all six faces. Do not use a jiffy bag alone. Tape the box securely. Write your name, return address and contact number on a piece of paper inside the box. Mark the outside clearly: FRAGILE — ELECTRONIC UNIT.
- Send it to us. Address: Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ. Use a tracked, signed-for service — Royal Mail Special Delivery or a courier with tracking. Keep your proof of postage.
- We clone and bench-test it. Once received, we extract your original data, transfer it to a tested unit and verify full functionality on our bench before anything goes back in a box.
- We return it free of charge. Your cloned BCM comes back via free tracked courier, typically within 3–5 working days of us receiving it.
Why Does Mail-In Beat Going to a Ford Dealer?
Dealers will typically quote for a new OEM BCM, a programming session and sometimes a key relearn — the combined bill regularly lands between £400 and £800 before you've even factored in labour. And the lead time on a dealer-ordered module in 2026 can stretch to two weeks or longer if it's on backorder. Our mail-in cloning service costs a fraction of that, turns around in 3–5 working days, and delivers a unit that's already data-matched to your vehicle. You fit it, connect the battery and drive.
Beyond the cost difference, there's the independence factor. Your car is off the road while the BCM is out. Every extra day it sits waiting for a dealer appointment or a parts delivery costs you money, inconvenience or hire car fees. Our mail-in model is built around minimising that dead time — fast intake, fast bench work, fast return.
Local to North London or Hertfordshire?
If you're within roughly 60 miles of Enfield, you're welcome to drive in directly to our unit at Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ. Many customers from North London, Hertfordshire, Essex and Cambridgeshire bring their vehicle or the removed module in person for a same-day or next-day turnaround depending on workload. Call ahead on 0203 489 2610 to check availability.
What Other Ford Electronic Repairs Does TVC Offer?
Ford BCM cloning sits alongside a full suite of electronic repair services at TVC. If your Ford has developed airbag warning lights or the SRS module has crash data stored after an accident, our crash data reset and SRS airbag module service handles that by post in exactly the same way. For Ford models with automatic gearbox faults — slipping, harsh shifts or failure to engage — our mechatronic repair service covers DSG and a range of other automatic transmission units. And if your Ford has a clutch actuator fault causing gear selection issues, the clutch actuator repair page covers the most common units we see.
