Diagnostics & warning lights at Oswins Garage

Engine management light on, limp mode, an intermittent electrical fault nobody can find — we diagnose every make with professional multi-brand equipment, and for Ford, Peugeot, Citroën, DS Automobiles, Vauxhall, Mercedes-Benz, Volkswagen, SEAT & CUPRA, Škoda, Audi, Land Rover and Jaguar we go further with the manufacturer's own dealer-level systems.

  • A diagnosis, not just a code read — we tell you the cause and the fix
  • Dealer-level systems for twelve makes; professional multi-brand tools for the rest
  • Live data, oscilloscope and wiring diagrams for the awkward electrical faults
  • Fixed diagnostic fee agreed before we start

Questions people ask

What is the difference between a code read and diagnostics?

A code read tells you a sensor reported a problem. Diagnostics tells you why — the wiring, the component or the software behind it — so the fix is the right one first time.

Book online, straight into our workshop diary

Pick a time that is actually free — the booking goes into the same diary we run the workshop from, so there is no "we'll ring you back to confirm" for servicing and checks. Diagnostics and repairs: describe the fault and we will call you.
