What does an alternator do?

The alternator is the device responsible for generating electricity to charge the battery. It’s coupled with the engine drive, which means whenever the car is running, the battery is being charged. Without a charged battery there is no delivery of power to the electrical components or to generate the sparks used to combust the fuel in the engine.

How often should an alternator need replacing?

An alternator typically lasts around 7 years or between 100k and 150k miles.

The law, vehicle regulations and your MOT

Without a correctly functioning alternator, your car is unlikely to hold enough charge in the battery to drive for any purposeful length of time. Having said that, the alternator won’t be tested during an MOT, so as long as the battery has enough charge for the engine and other electrical components to run for the duration of the examination, then it can still achieve a pass. We do not recommend this in any circumstance. If there is a problem with your alternator, you should have it repaired or replaced as soon as possible.

What happens when we replace your alternator?

• Our efficient and fully qualified mechanics will test the voltage output of the alternator, inspect the car’s electrical systems and all alternator ancillaries (drive belts, cables, etc.).
• Wherever necessary, the alternator will be replaced, and you will be advised of any other connected or associated problems arising from its malfunction.
• You will also be advised of any other parts that may need to be replaced for the best operation and health of your vehicle.
• Once the faulty alternator has been replaced, our mechanics will test it thoroughly to ensure the correct running of the new part and make any adjustments required for its premium operation.

What causes an alternator to stop working correctly?

An alternator might break down due to a bearing failure, preventing the rotor from spinning freely. Fluid leaks or a too tight belt (or a loose belt slipping) can also cause damage and premature wearing.

Symptoms of a malfunctioning alternator

When the battery is flat

If your battery is flat and refuses to accept charge through normal driving, then your alternator could be the problem.

The lights aren’t as bright as normal

If your headlamps aren’t as bright as normal or the function of other electrical components is weak, your alternator may not be supplying as much charge to the battery as it needs.

The battery warning light is illuminated on the dashboard

All warning lights are an indicator that a sensor has detected a failed component or poor operation. A battery warning light could be connected to your alternator performance.

Volkswagen (often shortened to VW) is a German automobile manufacturer founded in 1937 by the German Labour Front, a Nazi labour union.

The Golf’s 64k registrations in 2018 added to the vast tally of 3.4million Volkswagen cars on the road today.

High quality, highly rated, appropriately priced cars

VW cars achieve consistently strong reviews and are highly respected by critics and drivers alike. They are renowned for investing more money into research and development than almost any other marque and distributing their wealth of motoring knowledge across the many partner brands under the VW Group umbrella.

The Volkswagen Beetle: The ‘people’s car’

A classic of its time, originally named the Volkswagen Type 1, it soon became nicknamed the Beetle due to its unique shape, and subsequently the bug. The unique looking car was designed by Ferdinand Porsche for Adolf Hitler, who wanted a cheap and simple mass-produced car to travel around his country’s new road network.

The new model Beetle, originally launched to celebrate the original classic in 1997, and with an updated successor in 2011, was designed around the VW Jetta platform sharing much of its build with the Jetta and Golf. VW announced in 2018 that the Beetle would finally be removed from production in July 2019.
