Diagnosing a turbo fault on the Audi A3 2.0 TDI 184 before any replacement
Before ordering a new turbo for your Audi A3, it is essential to confirm that the turbo is actually the cause of the problem. A whistling noise under acceleration, a gradual loss of power, an engine warning light accompanied by a fault code related to boost pressure, or abnormal exhaust smoke (blue smoke indicating oil consumption, or black smoke pointing to an overly rich mixture) are all signs that should alert the owner of an A3 fitted with the 2.0 TDI engine. Before confirming the replacement, check for oil leaks at the hoses, inspect the air filter, ensure the intercooler is clean, and check for any abnormal play on the turbo shaft. This diagnosis helps rule out a secondary cause (a cracked hose, a faulty pressure sensor) before investing in a new turbocharger.

The engine codes covered are CUNA, CUPA, CUWA, CYLA, DFMA, DFUA, DGCA and DJGA. Before placing an order, we recommend checking the reference printed on your old turbo as well as the engine codes shown on your vehicle's identification plate, to ensure a perfect fit.
Warranty and delivery for this Audi A3 turbo
This new turbo is sold as a straightforward purchase: no old unit to return — there is no return or collection of your old turbo. Delivery is made in a single shipment. The part carries a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over several instalments, in up to 10 instalments.
Fitting advice to protect your new turbo
On the 2.0 TDI engines fitted to the A3, the longevity of the turbo depends directly on the quality and regularity of oil changes, as well as the condition of the air filter. Before fitting, check the oil circuit, the intake hoses and the air intake to eliminate any contaminants that could immediately damage the new compressor. Once the turbo is installed, prime it with oil before the first start-up, so that the bearings are properly lubricated from the moment the engine is running and any dry start is avoided.
