Injectors and fuel system
Engine jerking, smoking or cutting out? We check the injectors, the high-pressure fuel pump and the fuel filters where your truck stands.
Symptoms
- The engine jerks, runs rough or cuts out
- Black or white smoke from the exhaust
- Hard starting after a stop or noticeably higher fuel use
- A smell of fuel or signs of a leak at the injectors
What we do on site
We check the system pressure, injector back-leak and injector corrections. We replace fuel filters, injectors and the high-pressure fuel pump, and after the replacement we bleed the system and check how the engine runs with the tester.
Roadside repair limits
- Replacing injectors and the pump on site depends on parts being available; if they need ordering, we agree a date.
- We test and recondition injectors on the test bench in our workshop in Jasień, not at the roadside. We don't recondition high-pressure fuel pumps: a damaged pump is replaced.
What to send on WhatsApp
- The make, model and year of the tractor unit
- Your location: a location pin, or the motorway, direction and nearest exit
- A recording of the engine running (10–20 seconds, with sound)
- A photo of the warning lights and messages on the dashboard
