New Citroën C4 Turbo – Ref. 853603-5002S

Signs of a worn turbo on the Citroën C4 1.5 BlueHDi 110

On the Citroën C4 fitted with the 1.5 BlueHDi 110, a turbo nearing the end of its life often makes itself known through a loss of power under acceleration, an unusual whistling noise from under the bonnet, an engine warning light, or abnormal exhaust smoke (blue or black). Excessive oil consumption, hesitation on pick-up, or increased fuel consumption are further warning signs that should not be ignored. These symptoms generally point to worn bearings, excessive shaft play, or an oil leak on the turbine side, and call for prompt replacement to avoid damaging the engine.

Exchange basis and warranty on this Citroën C4 turbo

This turbo is sold on an exchange basis: return of the old turbo is required, in accordance with our Terms and Conditions.

Advice before and after fitting on the C4 1.5 BlueHDi

On this engine, turbo longevity is closely linked to lubrication: always use the recommended oil grade and adhere strictly to the service intervals. A clogged air filter or a cracked intercooler will also accelerate premature turbo wear, as will habitually driving at high revs. Before fitting, check the oil circuit (hoses and return pipe), the condition of the intake hoses, and the cleanliness of the air intake. When starting up for the first time, prime the turbo with oil before the initial start to ensure immediate bearing lubrication. Payment for your order can be spread over several instalments, in up to 10 instalments.
