Land Rover Defender/Discovery Td5 NNN/MSB immobiliser delete service

Land Rover Td5 ECU Immobiliser Delete Service

We offer a professional immobiliser delete (“immo off”) service for all Land Rover Td5 ECUs (Discovery 2 and Defender).

If your vehicle suffers from immobiliser problems – common on older Td5s – this service removes the security link between the ECU and the vehicle’s immobiliser, allowing the engine to start without needing the original security system to function.

Benefits:

• Fixes no-start issues caused by immobiliser faults (e.g. engine cranks but won’t fire).

• Allows use of Td5 engine in engine swaps or conversions without requiring matched keys/BCU.

• No need to replace BCU, key fobs, or security components.

• Plug-and-play solution – just refit the ECU and start the vehicle.

Supported ECUs:

We cover all Td5 ECU variants, including:

• MSB101080, MSB101110, MSB101120, MSB101130, MSB101150, MSB101170, MSB101181, MSB101360, MSB101361

• NNN000120, NNN000130, NNN000150, NNN500020, NNN500250, NNN500250A, NNN500340, NNN500430, NNN500500, NNN500520

Additional Options Available:

While your ECU is with us for immobiliser delete, you can also choose from:

• Performance Remap – Stage 1 or Stage 2 maps for improved torque, drivability, and fuel economy.

• Convert Defender ECU ↔ Discovery ECU – swap maps between Defender and Discovery 2 ECUs.

• Manual / Automatic Conversion – change ECU coding to suit manual or automatic gearbox.

• Dual Map Upgrade – two switchable maps (e.g. economy + performance) using factory cruise control buttons.

Service Information:

• Your original ECU is modified and returned – no additional coding required.

• Turnaround usually 1–3 working days.

• 12-month warranty on all work.

This is a cost-effective, reliable solution for Land Rover Td5 owners struggling with immobiliser issues or undertaking engine swaps and conversions.
