Why are authorised parts and service so important for your pump or injector?

We see people all the time who have tried to go down the cheaper route for pump and injector repair and found that it didn’t work. They have come to us because they have no recourse with the original garage and we have to re-do the job from the start, costing time and money. Worse, some bad pump or injector repairs even end up damaging the engine further.  

 As authorised repairers for pump and injector manufacturers Bosch, Denso, Delphi, Siemens etc, you know that the repair will be carried out to a high standard, with authorised parts and one year warranty. Don’t get caught paying for cheap work that will cost you more in the long run!

I think I have a problem with my diesel pump or injector, what next? 

First, we would recommend ringing us and talking to one of the office staff. They will guide you through what kind of injector or pump is in your vehicle and what in the car might be causing the problem. Once you know that the fuel system is causing the issue, the office staff will also be able to tell you if we can repair or recondition your pump or injectors, or if they are available from new, etc. 

We can organise collection (see Collection services tab, above), or arrange a time to drop it off. 

What are your prices? 

The cost of repair can vary significantly between different types of pump and injectors. The best way to figure out what your repair will cost, is to talk to our office staff.


-We usually charge €15- €25 plus VAT per injector to test and this fee is waived if you go ahead and repair the injector with us (certain injectors can be up to €45 to test, but we will make you aware of that before we test them).

-To test a pump we charge between €90 to €120 plus VAT, and again this price would be included if we go on to recondition the pump. 

-To do a full diagnostic test on a car the average is €100 plus VAT

Prices for repair and recondition vary between type of pump and injector, but once the test is done we will give you a full price. We will never go ahead with work without informing you what is involved and what it is going to cost. 

Despite recent scandals involving diesel cars, a well maintained diesel car gives out very low emissions. Modern diesel engines which meet rigorous EU regulations are built with technologies like AdBlue and diesel particulate filters (DPF) are designed to filter out soot and other emissions linked to air pollution. It is important, however, to keep your vehicle well maintained and your injectors and pump are a big part of this. As well as keeping emissions down by maintaining vehicles, and their pump and injectors, Diesel Injection Services also works towards sustainability in our own practices. We have attained an ‘Ecocert’ certificate from Econcertive who monitor our commitment to sustainability and environment.


Isn’t diesel bad for the environment?
