Not sure you've found the right part?
Why does the turbo fail on the Audi A3 1.4 TFSI?
On the 1.4 TFSI/TSI petrol engine fitted to the Audi A3, the turbocharger is put under considerable strain during hard acceleration and spirited driving. The most common causes of failure are linked to inadequate lubrication: incorrect engine oil grade, oil changes left too long between intervals, or a gradual build-up of deposits in the oil lines feeding the turbine. Switching the engine off abruptly after prolonged use at high revs can also weaken the turbo bearings, as can a clogged air filter or a poorly maintained intake system, both of which upset the pressure balance essential to the correct operation of the forced-induction system.
Compatibility with Audi A3 engines
This new turbo is compatible with reference 49373-01003, intended for Audi A3 models fitted with the 1.4 TFSI/TSI petrol engine (122 to 125 hp), with an engine capacity of 1390 cm3, identified in particular under engine codes CAXA, CNVA, CAXC, CMSA and CMSB. Before placing an order, it is strongly recommended that you check the reference printed on the old turbo fitted to your vehicle, to ensure perfect compatibility with your exact engine.
Warranty and delivery for the Audi A3 turbo
This turbo is new and sold as a straightforward purchase: there is no old unit to return, no collection and no exchange. You receive a single delivery — the new turbo. The part carries a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over up to 10 instalments.
Fitting advice for your A3
Before installing the new turbo on your Audi A3, have the oil circuit thoroughly checked (feed and return hoses), along with the air filter and the condition of the intercooler, to prevent any contamination or pressure loss that could shorten the life of the new component. When starting the engine for the first time, it is essential to prime the turbo with oil to ensure the bearings are lubricated immediately from the very first start, before the engine is put under any load.
