Manufacturer-level scan
Read the relevant control units with tools suited to the vehicle rather than relying on a basic generic code reader.
Diagnostics for your Mercedes-Benz GLS
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.
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.
