Turbo 1.8 TDCi

On the Ford 1.8 TDCi, the stated power output alone is not enough to identify the turbo: the engine code is the only reliable reference

A 1.8 TDCi 100 hp can take entirely different turbo references depending on the vehicle model and the engine code stamped on the block. It is the engine code — not the power output alone — that points you to the correct manufacturer reference.

The 1.8 TDCi is found across the entire Ford range: Focus, C-Max, S-Max, Galaxy, Mondeo, Tourneo, Connect and Transit all share this engine capacity in variants ranging from 90 to 125 hp. Yet the same power output — 100 hp, for example — can appear under several distinct engine codes, and each of those codes may correspond to its own manufacturer reference. The power output listed in the technical specification is therefore only a first filter, and is not sufficient on its own.

Numerous engine codes, frequent overlaps

This guide covers 24 distinct engine codes for the 1.8 TDCi alone. Some codes — such as FFWA, QYWA, HCPA, HCPB or P9PA — appear under several different power outputs, meaning that the same code can cover anything from 90 hp to 125 hp depending on the vehicle. Conversely, certain codes such as KKDA, KKDB, CDLYNX or KHBA are specific to a single power variant. Before placing any order, reading the engine code directly from the block — not from the registration document — remains the most reliable method for identifying the correct manufacturer reference and its equivalents.

Failure causes and symptoms not to overlook

On this diesel engine, turbo failures are most commonly linked to poor lubrication: old oil, a clogged oil circuit, or revving the engine too soon after a cold start. A blocked intake circuit or a failing diesel particulate filter can also cause premature bearing wear or deterioration of the CHRA seal. The most common symptoms are abnormal exhaust smoke, a distinctive whistling noise under acceleration, and a loss of power that can trigger limp-home mode. Replacing the turbo without addressing the root cause will invariably lead to a repeat failure. All turbos offered in this collection are brand-new units, sold as a straightforward purchase with no old unit to return.
