Mini Cooper Won’t Start – JBE Repair

mini cooper won't start, jbe mini cooper, mini cooper jbe repair

Are you struggling with a Mini Cooper that won’t start? Unfortunately, this is a common problem that is faced by many owners, and is the result of a faulty junction box electronics control module (JBE) within the Mini Cooper.

The JBE, also known as the Body Control Module (BCM), serves as the central control unit for various electronic systems in Mini Cooper (2006-2015) models. Acting as the brain behind fundamental electrical functions in the vehicle, the JBE is responsible for controlling central locking, the alarm system, indicators, windows, wipers, and more specifically, the fuel pump relay.

Because the fuel pump relay aids in delivering fuel to the engine, failure of the JBE will cause a fuel pump relay fault, resulting in a Mini Cooper that won’t start. Other potential symptoms of failure include erratic behaviour of the vehicle’s electronics, such as windows or indicators, as well as problems with the central locking.

Finding a Mini Cooper JBE repair from the manufacturer will be difficult, as they will instead suggest that you purchase a completely new, but costly, module. This will not only be an expensive investment, but as extra labour will be required to reprogram the new JBE, the process will take more time. In addition to this, it is likely that the new JBE will still have the original fault, resulting in further issues with your Mini Cooper not starting.

But, there is no need to worry. We are able to provide a Mini Cooper JBE repair solution that will both save you time and money. With our full test and rebuild service, the JBE for your Mini Cooper will be rebuilt within 2-3 working days.

If the BCM is found to be faulty, the unit is stripped of all failing components and replaced by those of a higher standard of quality.



We retain all original programming during the rebuilding process, simply plug and play once you receive your unit back.
