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.
Mercedes-Benz
Mercedes-Benz is a German global car manufacturer and a division of Daimler AG. They were established over 100 years ago in 1926 and have grown to be the biggest selling premium vehicle brand in the world.
How popular is Mercedes in the United Kingdom?
The number of Mercedes cars on the road in the UK continues to rise, reaching 1.9million by the final quarter of 2018. There are almost 5 times as many Mercedes cars on the road as there were in 1995, showing just how popular this marque has grown to be.
Helping these powerful statistics on their way, the Mercedes A-Class was announced as the 8th best selling car in the UK in 2018. The premium family hatchback is vying for position against the ever-popular VW Golf—the current leader in this class.
Premium executive models of every shape and size
Mercedes deliver hatchbacks, saloons, estates and coupés at every size from their A- to E-Class ranges, as well as executive SUVs, the V-Class MPV, and of course, a more than desirable selection of convertibles and roadsters.
With prices rising to well over £100k, Mercedes cars are a great contender as the executive car of choice.
Mercedes-Benz: Giants of Formula One
Mercedes has always been a keen player within the F1 championship, taking their first 2 titles back in 1954 and 1955. Through the 1990s they joined forces with McLaren as an engine provider and part owner, bringing titles for both Mika Häkkinen and Lewis Hamilton and a constructors championship in 1988.
Their current and outright domination of the sport began in 2014, as a team in their own right, it has featured 5 straight constructors titles, with Lewis Hamilton taking 4 world championships and Nico Rosberg taking the other in 2016.
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.
Common questions about booking at Fixter
Common questions about booking at Fixter
All of our drivers are fully insured and your vehicle is always protected.
We put our drivers through rigorous vetting and training before they are able to drive your vehicle. All of our drivers must have at least 3 years of driving experience, hold a clean driver's licence, be over the age of 21, capable of driving both manual and automatic vehicles and pass a criminal background check.
Your vehicle will be assigned to a driver who is responsible for collecting it from your home, delivering it to the garage and returning your vehicle once all work is completed.
Sometimes we might coordinate with a garage for them to send their own driver to collect your vehicle. In this instance, you are protected as you would be if it was a Fixter driver.
One of our in-house mechanics will factor in the make and model of your car, as well as the work that needs doing. They will then allocate your booking to the most appropriate Fixter garage in your area, and we’ll email you to confirm.
Here’s why only 1 in 20 garages pass our selection criteria:
We only choose garages registered as a Limited Company, with a minimum of 3 years of trading.
We assess each garage's various established affiliations (e.g. Bosch / Unipart / Garage).
We perform an online audit: Fixter only selects garages with at least a 4 star customer rating.
We make sure to visit each garage in person. Our in-house mechanics evaluate the quality of equipment, staff qualifications, capacity, and technical capabilities of selected servicing centres. Fixter only works with garages which strictly use manufacturer-equivalent parts.
After all requirements are fulfilled, we negotiate preferential terms with each selected (including parts, labour, oil, and MOT test rates), so we can pass it along to our customers.
All parts used in repairs and services carried out by Fixter are either manufacturer parts or equivalent. This guarantees that only the best quality parts are used in your vehicle. We offer a 12-month warranty, meaning that should anything should go wrong with the parts or labour we’ll take care of it, free of charge.
We take your card details when you book online, but nothing is charged to your card until all the work has been approved by our in-house experts, and satisfactorily completed.
No extra work will be carried out without your consent. If additional work is required, one of our in-house experts will call you to walk through any diagnostic reports, recommendations or additional quotes from the mechanic working on your car. We check every quote to make sure the work is required and has been fairly priced.
Note: If you need to update your payment details to pay for your booking, the team will send you a secure link to add the new card details.
If your car fails its MOT at one of our garages, but you believe that your car should have passed, you'll have the option to take your car to another garage to do a new MOT test. If your vehicle passes the MOT at another garage, we’ll refund you for the original MOT test that you carried out with us. Collection and delivery fees are non-refundable.
All Fixter bookings are covered by a 12-month warranty on parts and labour.
If there’s a problem (with either parts or labour) up to 12 months after your booking date, we’ll sort it out for you, completely free of charge.
Just email support@fixter.co.uk or call our team on 0330 808 9527 and we’ll take care of it.
Note: this doesn't apply to an air con regas as leaks can occur at any time.
We understand that things change.
If you need to cancel or change your booking, please let us know asap. Our agents spend time finding you a top-rated garage, which is then booked to take care of your vehicle. In many cases, parts are ordered in advance. As a result, we operate a 72-hour cancellation policy. If you have a confirmed booking with us and need to cancel within 72 hours of the appointment, a cancellation fee of £20 may be applied.
We want to avoid that so our agents will work with you to try and find a new appointment instead. To discuss changing or cancelling a booking, please email or phone on 0330 808 9527.
Our team works Monday to Friday from 8:30 am to 5:30 pm.
