Open sectionWhy do we only publish the price of the test?
Because every injector fails differently. One has a worn nozzle, another a bad valve, another a failed coil or piezo stack. Some faults are mechanical, others electrical. Without a diagnosis, any price would be made up.
So we do it the other way round: first we bench-test it for €15, then we give you a fixed price. No surprises, no obligation.

What people ask us most
How much does a diesel injector test cost?+
A bench test costs €15 per injector. It includes the delivery, return and spray test, plus an explanation of the fault.
How much does an injector repair cost?+
It depends on the fault: replacing a nozzle is not the same as a valve or a piezo stack. After the test we give you a fixed, no-obligation quote. If you don’t repair, you only pay the €15.
Do I need to bring the car?+
No. Just bring the injector or pump already removed. If you are a workshop, we can collect the parts with our fleet.
Which injector brands do you repair?+
Bosch, Denso, Delphi, Siemens VDO and Continental common rail injectors, both solenoid and piezo, plus unit injectors.
How long does the repair take?+
The test is quick. Repair time depends on the part and the fault, and we confirm it together with the quote.
