Engine Diagnostic Services
Dashboard warning light on? Our experienced technicians use dealer-level diagnostic equipment to accurately identify faults and recommend the correct repair.
Professional Vehicle Diagnostics
Modern vehicles rely on sophisticated electronic systems to monitor engine performance. When a fault occurs, your dashboard warning light alerts you to a problem that should be investigated.
At The Garage Bedwas, we use professional diagnostic equipment to quickly locate faults, helping you avoid unnecessary repairs and get back on the road with confidence.
Oxygen Sensor
Faulty oxygen sensors reduce fuel economy, increase emissions and can damage your catalytic converter.
Ignition System
Misfires, rough running and poor acceleration are common signs of faulty spark plugs or ignition coils.
MAF Sensor
A faulty Mass Air Flow sensor can cause hesitation, stalling and reduced engine performance.
DPF & EGR
Blocked DPFs and EGR valves are among the most common diesel engine management faults.
Fuel Injectors
Injector problems can cause poor starting, rough idling, increased smoke and loss of power.
Battery & Charging
Weak batteries and charging faults regularly trigger dashboard warning lights on modern vehicles.
