The BSI (Built-in Systems Interface) is the central control unit on Peugeot and Citroën vehicles, managing much of the electrical system. BSI faults can cause anything from minor electrical glitches to a complete non-start.
We specialise in BSI programming, configuration, and repair for Peugeot and Citroën vehicles, resolving issues that often leave general garages stuck.
We configure and set up BSI units to your vehicle’s exact specification.
Correct configuration ensures every connected system communicates and behaves as it should.
When a BSI unit is replaced, it needs programming and synchronising before the vehicle will run correctly.
We program replacement modules and match them to your vehicle, including keys and immobiliser where required.
BSI faults are a common cause of non-start and unpredictable electrical behaviour.
We diagnose these faults and synchronise the electrical system, getting your Peugeot or Citroën running reliably again.
We provide BSI programming for customers in Sandy and the surrounding areas, including Biggleswade, Bedford, St Neots, Shefford, Potton, and Hitchin.
