Basic fault-finding

For detailed advice, consult the vehicle handbook, a workshop maintenance manual or a qualified mechanic.

The table that follows gives only a brief guide to simple fault-finding and remedies.

If you have any doubts about the roadworthiness of the vehicle, seek specialist help without delay. Don’t ignore any warning signs.

Some minor faults can be easily identified and corrected, but problems with more complex engine management and electronic systems are better left to qualified mechanics – especially when the vehicle’s warranty might be affected.

Recognising basic faults

Maintenance

Check all levels and systems as recommended.

Changing filters and spark plugs at the recommended intervals will help keep your vehicle reliable and prolong its life.

Air filter

Replace the air filter at the intervals recommended by the manufacturer, or sooner if the vehicle is used in exceptionally dusty conditions.

Overhead camshaft engines

On this design of engine it’s vital to have the camshaft drive belt (if fitted) replaced at the recommended intervals. Serious damage can be caused to the engine if the belt breaks.
