If your car is spluttering, generally running rough or flashing a Engine Maintenance Light, you should book in a diagnostic check.
n the event of your EML (Engine Maintenance Light) flashing, we use an Electronic Diagnostic machine. This plugs into the car's computer, and can diagnose areas in need of repair.
We use a UV Smoke Tester to compress the engine with a UV smoke, so leaks are visible using a black light.
This same machine can be used on water and exhaust systems also.
