BMW inspection & fault finding

A fault code is the start of the investigation.

Warning lights, noises, non-starts and intermittent faults inspected by BMW-trained technicians who understand the systems behind the code.

Test the cause before recommending the repair.Clear findings. Clear options. Your approval before work begins.

What LJ can help with

Specialist knowledge, explained properly.

We begin with what you want from the car, inspect what is actually happening and explain the sensible route forward without burying you in technical jargon.

  • Warning-light investigation
  • No-start and electrical faults
  • Noise and drivability inspection
  • ISTA diagnostic testing
  • Clear repair plan and timescale
01

Listen to the customer

When it happens, what changed and how the car behaves often matters as much as the stored fault information.

02

Test the system

Live data, guided testing and practical BMW experience are used to narrow the fault before parts are recommended.

03

Explain the repair

You receive a plain-English explanation of what was found, what is needed and the expected cost and timescale.
