Hyundai i30 Turbo

The i30's turbo changed four times across its engine codes, not just with its engine capacity

The i30 spans several distinct generations, each of which introduced new turbo references — including at the same engine capacity. The 1.6 CRDi, the model's core engine, has not always used the same turbo: depending on the power output chosen (90, 110, 116 or 128 hp) and the associated engine code (D4FB or D4EA), the references differ. Relying on engine capacity alone risks ordering the wrong part.

Diesel: four power outputs in the 1.6, and a 2.0 that must not be confused with it

The 1.6 CRDi is available in 90, 110, 116 and 128 hp — each variant corresponds to a specific reference (including 775274-5002S, 282012A700, 757886-5008S). The 2.0 CRDi (136 or 140 hp, code D4EA, reference 766111-5001S) is an entirely different architecture — larger in size and not interchangeable with the 1.6 turbos. Both diesel families use variable-geometry technology, which makes them sensitive to vane fouling and vane play when lubrication is insufficient.

Petrol: the 1.0 T-GDI, a small engine that needs close attention

The 1.0 T-GDI 120 hp (codes G3LC / G3LE / G3LF, reference 892599-5001S) is the only turbocharged petrol engine in the range. Its wastegate design and small oil volume mean that the quality and regularity of oil changes directly determine the service life of the CHRA. Any carbon deposit in the oil feed can damage the bearings. On both petrol and diesel engines, it is essential to identify and rectify the root cause of the failure — air leaks, a degraded oil circuit, fouling — before any replacement is carried out, regardless of the reference involved.
