  • Nikos from Manchester

    I was very skeptical initially with the service I was going to be provided by Fixter. Nevertheless it is very convenient that they come and get your car from any place and date. So I booked for a major service on the date and place I wanted. On that day, a guy came with his folded bike (10mins late)...

The London Borough of Merton is located in South West London with a population of around 206,000.

Most famous for its most well known commercial district of Wimbledon, due to it being home to the internationally renowned Wimbledon tennis tournament.

The Wimbledon Tennis Championships, the only remaining major played on grass courts, has been held in London since 1877 and is famous as part of the tennis Grand Slam. 1968 was the first year prize money was awarded to the players, totalling a grand sum of £26,150 with the men’s title winner taking a £2,000 cheque. The prize money for 2019 will total £38million with £2.35million each going to the men’s and the women’s singles winners.

Merton is also home to AFC Wimbledon (originally Wimbledon FC) who famously climbed from the fourth division to the first in three successive years from 1983–1986, and soon after in 1988, beating Liverpool in the FA Cup Final.

Merton was also the home of the ITV police drama The Bill, with the Sun Hill police station regularly being filmed within the borough.

The most popular cars in Merton and Southwest London

Close on its heels—and in order of popularity—are the Volvo XC90, Land Rover Discovery Sport, Volkswagen Tiguan and the Audi A3 Sportback.

What is a diagnostic inspection?

Modern cars have an onboard computer or Engine Control Unit (ECU). This continually assesses performance, with sensors throughout the car letting the ECU know of issues such as raised engine temperature, low fluid levels or problems with emission levels or the windscreen wipers. The ECU triggers an error once a problem has been found, and the relevant dashboard warning light will flash, but there are hundreds of potential error codes, which only specialist diagnostic equipment can read. So when a warning light flashes on the dashboard, a diagnostics check is needed to assess how bad the problem is, and what may have caused it.

We use state of the art diagnostic equipment

Live data shows multiple readings from across the engine to assess whether everything is working as it should. The equipment can also check and rectify braking systems where there’s an electronic handbrake, and adjust headlights where possible. You don’t need to go to a dealership to get diagnostic testing done. Most garages and workshops will carry out diagnostic testing for nearly all models and types of vehicle.

What happens at a Fixter diagnostic inspection

We charge a fixed fee for diagnostic testing that can be done while you wait. This is usually done within an hour, but if further work is required, it will clearly take more time. Our highly-trained and qualified mechanics will give you a no-charge, no-obligation repair quote if testing highlights issues with the engine or anything else, and talk you in detail through what is needed to put things right.

So next time a dashboard warning light flashes on, don’t pay dealership prices for diagnostic testing. Let us manage it all for you, picking up your car for its testing, and ensuring a fair price and a reliable service.

What happens when my dashboard illuminates a warning light?

The warning light is just the beginning—it doesn’t give the whole picture. There are hundreds of parts in your engine, so the exact nature of the fault may not be immediately apparent.

Examining fault codes to identify the problem

A diagnostic check accurately identifies the fault, avoiding more serious problems that could lead to costly repairs, potential safety hazards or worse damage. With these tests, your car is plugged into sophisticated diagnostic equipment which reads the error codes your car’s ECU has generated to explain the issue in full. Diagnostic checking looks for errors across various vehicle systems, including tyres, engine management, lights, emissions and more.
