Ford 1.8 TDCi engine: reliability and faults

Diesel · 1,753 cm³ · 100, 115, 125 hp · since 1998

Good choice, check first
Reliability
4.0/5

2 known faults

Verdict

A 1.8-litre four-cylinder diesel engine, fitted to the Ford Focus, C-Max, Mondeo, S-Max, Galaxy and Tourneo Connect. The dual-mass flywheel and clutch often fail early, especially on the 125 hp version, sometimes before 100,000 km, and the injectors and their seals need watching (smoke, jerking). Have the clutch and flywheel priced on the test drive.

Known faults

Dual-mass flywheel and clutch

Severity 2/3 · Costly

Caradisiac describes recurring premature wear and failure of the dual-mass flywheel, and therefore the clutch, especially on the 1.8 TDCi 125, sometimes before 100,000 km; Ford sometimes refuses a goodwill contribution at first. Owners quoted by Fiches-auto have replaced the clutch and flywheel, one for €1,500.

Injectors and injector seals

Severity 2/3 · Costly

Caradisiac reports injectors needing cleaning or replacement on the 1.8 TDCi 125, and Fiches-auto leaking injector seals on TDCi engines (smoke, jerking). A September 2013 recall replaced damaged injector O-rings on 179 Mondeo, Galaxy and S-Max in France.
