A new turbo designed for real-world use in the Audi TT
The Audi TT fitted with the 2.0 TDI 184 hp engine is typically used for mixed driving, combining spirited road runs with shorter urban journeys. This constant variation in engine load, combined with the occasionally sporty driving style that suits this coupé, places considerable strain on the turbocharger — particularly during sustained acceleration and rapid pressure build-up. A new turbo restores performance in line with the original specification of this turbocharged diesel engine.
Compatibility of the turbo for the Audi TT 2.0 TDI
This new turbo is compatible with reference 821866-5009S, intended for the Audi TT fitted with the 2.0 TDI unit producing 184 hp, identified in particular by engine code CUNA. Before placing an order, it is strongly recommended that you check the reference printed on the old turbo or on the vehicle's identification plate, as certain engine variants may look similar whilst requiring a different reference.
Exchange and warranty for this Audi TT turbo
This turbo is sold on an exchange basis: the old turbo must be returned in accordance with the Terms and Conditions. The return is only required after the new turbo has been delivered and fitted, so that the vehicle is not left off the road during the process. A 12-month parts warranty applies, subject to fitting being carried out by a qualified professional.
Fitting and maintenance advice for the Audi TT 2.0 TDI
On this type of turbocharged diesel engine, premature turbo failure is often caused by a lubrication fault — whether due to incorrect oil, missed oil changes, or a clogged air filter. A damaged or fouled intercooler can also disrupt turbo operation and accelerate wear. Before fitting, the oil circuit, hose condition and air intake should all be checked to prevent any contamination of the new turbo. When starting the engine for the first time, priming the oil supply is essential to ensure the bearings are lubricated immediately from the very first start. Avoiding harsh cold-start rev increases will also help extend the life of the turbo on this model.
Flexible payment
Payment for this new Audi TT turbo can be spread over several instalments — pay in up to 10 instalments — subject to the options available at the time of ordering.
