Expert Mercedes ECU & TCU Cloning services in Ilkeston, Derby, and Nottingham.
Call Us Now: 07783630237JK Car Electrics provides specialist Mercedes ECU (Engine Control Unit) and TCU (Transmission Control Unit) cloning services throughout Derby, Nottingham, Ilkeston and the East Midlands. Modern Mercedes vehicles use FBS3 and FBS4 security protocols that tie modules to the vehicle—you cannot simply swap in a used part without proper adaptation. We use genuine Mercedes Xentry diagnostics to perform secure ECU/TCU cloning, virginising, and personalisation.
Whether your Mercedes-Benz requires engine ECU cloning in Derby, gearbox TCU programming in Nottingham, or 7G-Tronic module replacement in Ilkeston, our specialist team handles all Mercedes control module programming requirements. We work with all Mercedes-Benz models including C-Class, E-Class, S-Class, A-Class, B-Class, GLC, GLE, GLA, GLB, CLA, CLS, Sprinter, Vito, and V-Class vans. Our Mercedes ECU cloning service supports both petrol and diesel engines with MED17, EDC17, SID307, SID310, and CRD3 control units, while our Mercedes TCU cloning covers 7G-Tronic (VGS4-NAG2), 9G-Tronic (VGS-NAG3), and 7G DCT (VGS-FDCT) transmissions across Derbyshire and Nottinghamshire.
If your Mercedes displays fault code P051300, it means the engine start authorization (start enable) was not successfully issued — commonly occurring in vehicles with FDCT (Front-wheel Dual Clutch Transmission) systems.
This fault typically prevents the vehicle from starting or selecting gears and can point to communication, immobiliser (FBS) or gearbox module issues.
We specialise in diagnosing and repairing Mercedes FDCT "Start Enable Not Issued" faults, restoring proper communication between the engine ECU, gearbox control unit (TCU), and immobiliser system (FBS3 / FBS4).
Unlike generic gearbox faults, P051300 is not caused by mechanical failure — it's an electronic data integrity issue inside the FDCT TCU.
Primary Cause:
Battery voltage drop or disconnection (jump-starts, weak batteries, or long-term storage) → This can corrupt EEPROM or flash memory in the TCU, damaging stored start enable and configuration data.
Other Contributing Factors:
We are equipped to handle the latest FBS4 security protocol found on 2016+ Mercedes vehicles. Many independent garages cannot work with FBS4—we can.
We offer the same technical capability as the main dealer, but with faster service, mobile repair options and lower total cost. Main dealers only fit brand new units — we can program used or reconditioned modules where applicable, saving you hundreds of pounds.
Can you clone a used ECU/TCU I've purchased?
Yes, we can virginise and personalise used modules to your vehicle. Bring both the original (if available) and the donor module for cloning.
Do you support FBS4 vehicles?
Yes, we have the necessary hardware and software to handle FBS4 security on 2016+ Mercedes models.
How long does ECU/TCU cloning take?
Most cloning jobs are completed in 1-3 hours depending on the module type and coding requirements.
What if my original ECU is damaged beyond repair?
We can perform extended personalisation on many module types without the original ECU data, or we can work with partial data recovery.
Can you clone 7G-Tronic TCU without opening it?
Yes, we clone 7G-Tronic VGS4-NAG2 transmission control units without opening the conductor plate, preserving the original seals.
