BMW Diagnostics & Coding

Drivetrain malfunction, check engine or a dash full of lights? We read every BMW module and test properly before we quote.

All makes & modelsTypical time: 1 – 2 hours

A BMW has dozens of control modules talking to each other, and a generic code reader only sees a few of them. We scan the engine (DME/DDE), gearbox, ABS/DSC, airbag, body and comfort modules, read live data and road-test the car to reproduce the fault.

After a repair we carry out the resets, adaptations and registrations the car needs – battery registration, gearbox adaptations, injector codes and service resets – so the fix actually sticks.

What’s included

  • Full scan of all BMW modules
  • Live data & component testing
  • Road test to reproduce the fault
  • Battery registration & adaptations
  • Written findings and quote

Signs you need this

Check engine or drivetrain warning

Book soon
  • Misfire from a coil, spark plug or injector
  • Boost leak or faulty sensor (MAF, MAP, O2)
  • VANOS solenoid or Valvetronic fault
  • Fuel pressure, EGR or DPF fault on diesels

A steady light means book a scan soon. A flashing light or "reduced power" usually means a misfire – take it easy and have it checked straight away to protect the catalytic converter.
