Continental/Siemens VDO A2C59511610 1.8 TDCi (Lynx) Common Rail Injector (Ford Focus/Mondeo/C-MAX/Galaxy/S-MAX)
Continental (Siemens VDO) solenoid common-rail injector for the Ford 1.8 TDCi (Lynx/Duratorq) engine in the Focus II, C-MAX, Mondeo IV, Galaxy II and S-MAX. Ford OE 4M5Q-9F593-AD (FINIS 1355051); Siemens equivalent 5WS40086. Note: this is the Ford 1.8 TDCi injector, NOT the PSA 1.6 HDi DV6 part. Replacements are coded to the ECU with the injector correction value. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.
A leaking injector unbalances cylinder fuelling on the 1.8 TDCi.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationCode the injector correction value to the correct cylinder with Ford IDS before road test.
- InstallationRenew the copper combustion washer and leak-off seals; torque the clamp to spec.
- MisdiagnosisRead live back-leakage / cylinder-balance data to find the weak cylinder before removal.
- WarningDo not confuse this Ford 1.8 TDCi (Lynx) injector with the PSA 1.6 HDi DV6 part - confirm OE number 4M5Q-9F593-AD.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is injector A2C59511610?+
A Continental (Siemens VDO) solenoid common-rail diesel injector for the Ford 1.8 TDCi (Lynx/Duratorq) engine. Ford OE 4M5Q-9F593-AD (FINIS 1355051); Siemens equivalent 5WS40086.
Which vehicles use A2C59511610?+
Ford Focus II/C-MAX, Mondeo IV, Galaxy II and S-MAX 1.8 TDCi (Lynx).
Is it solenoid or piezo?+
It is a Continental/Siemens VDO solenoid common-rail injector.
Does A2C59511610 need coding?+
Yes - code the injector correction value to the correct cylinder with Ford IDS when fitting.
What are the OE part numbers?+
Ford 4M5Q-9F593-AD (FINIS 1355051) references this injector; the Siemens equivalent is 5WS40086.
Does it fit the PSA 1.6 HDi DV6?+
No - despite similar Siemens part-number families, A2C59511610 is the Ford 1.8 TDCi (Lynx) injector. Confirm OE 4M5Q-9F593-AD before fitting.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 1.8 TDCi run rough?+
A worn or leaking injector unbalances fuelling; read live cylinder-balance data and bench-test the suspect cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured A2C59511610 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated on a Continental-capable tester, then coded with Ford IDS on fitment.
