Professional Diagnostics
More Than Just
Reading Fault Codes
Modern vehicles rely on complex electronic systems. A fault code is often only the starting point — it tells us where to look, but it doesn’t always reveal the real cause.
At Mr Unique, our experienced technicians use diagnostic equipment, live data and practical testing to accurately identify the underlying problem and recommend the right repair.
We work on all makes and models, including Peugeot, Citroën, premium brands and electric vehicles.
