What it’s all about

… and if it’s the service for you.

It is essential that injectors are tested as part of the diagnostic procedure on all petrol vehicles, especially when faced with combustion related problems. The ASNU equipment is a highly advanced injector solution offering diagnostic, test and service function across a wide range of petrol vehicles, for standard injectors and piezo injectors.

We are able to clean, test and refurbish the majority of petrol fuel injectors, including piezo and standard, old and new, for the vast majority of makes and models. We are proud to offer an onsite injector cleaning service, with a fast and efficient turnaround. Our ASNU state of the art ultrasonic injector cleaning and testing machine is the most advanced available on the market and has been developed with capabilities beyond that of standard test facilities. It makes use of ultrasonic cleaning methods to remove dirt from the injector pintle and seats, returning fuel flow to the highest level of efficiency.

As a diesel injection specialist and Delphi main agent, we have naturally invested heavily into the diesel side of the market- but we are also now able to offer the highest quality of service when it comes to petrol systems too. Having taught the subject FSI Systems for some 14 years we know a thing or two about the system.

FAQs… we’ve got them all covered

What is injector diagnostics and servicing?

Injector diagnostics is a specialist service we offer whereby the petrol injectors fuel distribution, fuel droplet formation, fuel atomization and fuel delivery are all visually and physically checked and tested. The injectors then go through the ultrasonic cleaning procedure and the rubber sealing rings, plastic protection caps and filter baskets are replaced. Everything is then retested to ensure the injectors are all performing equally and as a balanced set.

What is ultrasonic cleaning?

Ultrasonic cleaning is a cleaning process in which ultrasonic sound is passed through a solution, producing millions of high energy bubbles. These bubbles release all of their energy when they make contact with a surface; in this case, the injector surface. This explosion of high energy removes contaminants and loose matter that has stuck to the solid surface and is an ideal method of cleaning high precision equipment.

Why should I clean my injectors?

Unfortunately, it is not possible to stop tiny particles of dust from entering the fuel supply, as it is not possible to stop substances passing through the fuel filter when you refuel. This contamination is made worse by modern emissions that recirculate air gasses. Piezo injectors are also very expensive to replace when they go wrong, therefore by cleaning and maintaining these injectors, you could be saving a lot of money over time.

How do fuel additives work?

Fuel additives do a good job of cleaning carbon deposits from both the inside of your engine and the valves . However there is no substitute for cleaning the injectors properly.

Will this service save me money?

Fuel economy is reduced when contaminants build up, and block the flow of fuel in your injector. By reducing and removing this debris and replacing the injector microfilter, you are restoring engine horsepower and performance. Not only this, but the spray pattern will then produce a highly efficient combustion, reducing unnecessary fuel consumption and also reducing atmospheric pollution.

Do you take card?

We accept all the major debit and credit cards, including Visa, Maestro, American Express and Mastercard.

Will my manufacturers warranty be affected?
No. We only ever use genuine or OE replacement parts that comply with Block Exemption Regulations, so you are no longer tied to going to a dealership and paying inflated prices to have your car services just to keep warranty intact.
