Diagnosing a turbo fault on an Audi Q3 2.0 TDI before replacement
Before considering replacing the turbocharger on your Audi Q3 fitted with the 2.0 TDI quattro engine, it is essential to confirm that the turbo is actually the cause of the problem. Loss of power under acceleration, blue or black exhaust smoke, an unusual whistling noise under the bonnet, or the engine warning light coming on are the first signs to look out for. A diagnostic scan tool check allows you to read any fault codes related to boost pressure, while a visual inspection of the turbo in situ helps identify abnormal shaft play, oil traces in the intake hoses, or a seized variable geometry mechanism. This diagnostic step avoids an unnecessary replacement if the fault is actually caused by a cracked hose or a faulty pressure sensor.
Turbo compatibility with Audi Q3 engines
This new turbo is compatible with reference 821866-5009S and fits Audi Q3 models powered by the 2.0 TDI quattro producing 184 hp. The engine codes covered are CUNA, DGCA, CUPA, CUWA, CYLA, DFMA, DFUA and DJGA. Before placing an order, we strongly recommend checking the reference printed on your old turbo or on the vehicle's manufacturer plate to ensure a perfect match with your Q3.
Exchange basis and warranty for this Audi Q3 turbo
This turbo is sold on an exchange basis: in accordance with our Terms and Conditions, return of your old turbo is required. It is only collected after the new turbo has been delivered and fitted, so that your Audi Q3 is not left off the road during the process.

Payment for your order can be spread over several instalments, in up to 10 instalments.
Fitting advice to protect your new turbo
On the Q3's 2.0 TDI, turbo longevity depends heavily on the quality and regular changing of the engine oil, a clean air filter, and an intercooler in good condition. Before fitting, check the oil circuit, intake hoses and air intake to prevent any contamination of the new turbo. When starting the engine for the first time, prime the oil supply to ensure immediate lubrication of the bearings, and avoid hard acceleration during the first few kilometres.
