FSI High Pressure Injector Service

Mr Injector UK has been working in injector diagnostics and restoration for over 30 years. We are one of the oldest Asnu test facilities.

Our GDI FSI machine has the capacity to test all manufactured high-pressure injectors from various manufacturers such as Mitsubishi, Bosch, Delphi and Magneti Marelli.

We can inductance test over 8000 pulses, perform static and dynamic flow checks and atomisation analysis to check droplet and directional spray patterns.

This service is for high pressure (GDI/FSI/TFSI etc) injectors that are working and not seized. This does not include hose to rail injectors, standard port injectors, side feed injectors or Siemens/Bosch Piezo injectors, these are listed separately.

The Method:

Your injectors are pre-cleaned, inductance load tested and run on a test rig as they would operate on your engine to check for any anomalies, we record this pre-service information on your report sheet.

All parts are removed then we ultrasonically clean and backflush before returning to the ASNU test bench for dynamic analysis, which includes spray pattern checks, leak off and dynamic balance checks.

After the test and service all new parts are installed where applicable and the report would be drafted and sent across to you with the findings.

High pressure injectors are very expensive; this service will allow you to properly diagnose which injectors are the problem injectors. We shall be able to see if they are serviceable thus saving you having to purchase new ones. If we can't service all your injectors, you only pay for the ones that are serviceable.
