New Alfa Romeo MiTo Turbo – Ref. 54309880000

Diagnose before replacing the turbo on your Alfa Romeo MiTo 1.3 MultiJet

Before placing any order, a thorough diagnosis of your MiTo is essential. Reading the fault codes from the engine management unit will often confirm whether there is under- or over-boost at the turbocharger. A careful road test completes the diagnosis: look for a loss of power under acceleration, abnormal exhaust smoke, an unusual whistling noise from the engine bay, or a drop in oil level with no visible leak on the ground. These symptoms, common on small turbocharged diesel engines, point towards a turbo failure rather than another component, before considering replacement.

The new turbo compatible with reference 54309880000 for the MiTo

This new turbo is compatible with reference 54309880000, intended for Alfa Romeo MiTo models fitted with a 1.3 MultiJet engine producing 80 or 84 hp, with an engine capacity of 1248 cm³. The engine codes covered are 199 B4.000, 199 B8.000 and 223 A9.000. Before ordering, always check the reference printed on your old turbo, as several power variants and generations have been fitted to the MiTo over the years, with parts that are not interchangeable.

Exchange and warranty for your MiTo

This turbo is sold on an exchange basis: return of your old turbo is required, in accordance with our Terms and Conditions. It is only collected after the new turbo has been delivered and fitted, so your MiTo is not left off the road. A 12-month parts warranty applies, subject to fitting being carried out by a qualified professional. Payment for your order can be spread over several instalments, in up to 10 instalments.

Fitting advice for the MiTo 1.3 MultiJet engine

On this engine, the longevity of the turbo depends closely on the quality and frequency of oil changes: degraded oil or an insufficient oil level will cause premature wear to the turbocharger bearings. Also check the condition of the air filter and ensure there are no leaks or cracks in the hoses connecting the turbo to the intercooler, as any air leak will distort the boost pressure. Before the first start-up, prime the oil circuit by filling the new turbo through the oil inlet port, to avoid any dry running on initial start-up. Driving too hard immediately after a cold start, without allowing the engine to warm up gradually, remains one of the main causes of premature failure on this type of small turbocharged diesel.
