Investigating running problems, overheating, oil pressure warnings, smoke, noise and loss of power.
Engine fault diagnosisFrom a warning light or unusual noise to a rebuild or replacement engine, we identify the likely cause and agree the next step before larger work begins.
Engine & transmission
Engine problems can have several possible causes. We use the symptoms, vehicle details and appropriate checks to work out what needs attention.
