A steady engine warning light usually indicates a non-urgent issue like a sensor fault or emissions problem, but it still needs checking. A flashing engine light means stop driving and get the vehicle towed — it indicates a misfire that can damage your catalytic converter. Either way, book a diagnostic scan as soon as possible.
Common signs include white smoke from the exhaust, overheating, milky residue on the oil cap, coolant loss without visible leaks, or bubbling in the coolant reservoir. We can pressure-test the cooling system to confirm.
It depends on the vehicle's value, the extent of the damage, and availability of replacement engines. We'll assess both options and give you honest advice on which makes better financial sense for your situation.
Most manufacturers recommend timing belt replacement between 80,000 and 120,000 kilometres. If your belt snaps, it can cause severe internal engine damage. We check your service records and advise on the correct interval for your specific engine.
