New SEAT Leon Turbo – Ref. 751851-5004S

What changes behind the wheel of your SEAT Leon with a new turbo

On a SEAT Leon fitted with the 1.9 TDI engine, a turbo in good condition makes itself felt from the very first miles: throttle response becomes crisp again at low revs, the engine regains its torque without excessive lag, and driving in town and on the open road feels smooth once more, with no hesitation or sense of restriction. A worn turbo, by contrast, means a gradual loss of power, heavier exhaust smoke, and driving that becomes a daily chore on a model so often used for long journeys.

Exchange basis and warranty for this SEAT Leon turbo

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

Fitting and maintenance advice for your 1.9 TDI

On this engine, turbo failure is often caused by insufficient lubrication, poor-quality oil or neglected oil changes, a clogged air filter, or a cracked intercooler allowing contaminants through. Before fitting, check the oil circuit, the condition of the hoses, and the cleanliness of the air intake to avoid contaminating the new turbo. When starting up, prime the oil circuit before the first engine start, then drive gently for the first few kilometres to protect the longevity of the part.
