SERVICING YOUR KEY CHECKLIST

Here, we identify ten common tender spots on your car that any reputable dealer or mobile mechanic will help you look after, avoiding costly replacements.

Engine management: Because of emissions regulations and the subsequent introduction of catalytic converters, Electronic Control Units (ECUs) are now more complex than ever before. ECUs are generally sealed units and repair is often impossible.

Exhaust systems: Most cars that were manufactured after 1989 are equipped with catalytic converters. If they're not properly checked and maintained and your vehicle needs a replacement, it will hit you where it hurts the most - your pocket. (Because catalysts contain precious metals, replacements are very expensive).



ABS systems: These contain a brain, a master cylinder, a pump and wheel sensors. Sadly, all are prone to failure. If your ABS fails, even if your brakes are functioning, your vehicle won't pass its MOT.



Automatic gearboxes: Many of these appear to be trouble free. However, as the odometer reading increases, so too does the possibility of failure. Most automatic gearboxes are managed by complex electronic systems - which makes maintenance even more of a specialist issue.



Electronically-controlled heaters: Push button heating systems can often be found in many executive and prestige vehicles. Stepper motors control air directing flaps throughout the car and, should a stepper motor fail, the system will jam. Unfortunately, the only solution is to remove the dashboard and replace the faulty unit.
