Fault finding & health checks

Diagnostics for your BMW 4 Series GC

A calibration can only be as good as the vehicle underneath it. We use manufacturer-level tools, live data and controlled testing to find the cause rather than replace parts by guesswork.

Manufacturer-level scan

Read the relevant control units with tools suited to the vehicle rather than relying on a basic generic code reader.

Live data & datalogging

Capture operating data under the conditions that trigger the fault so the diagnosis is based on evidence.

Pre-tune health check

Check boost, fuelling, temperatures, emissions systems and mechanical condition before asking for more output.

Before you book

Bring any fault codes, recent repair history and a clear description of when the issue occurs.
