What changes when you drive your Audi A4 with a healthy turbo

On an Audi A4 1.9 TDI, a properly functioning turbo makes itself felt immediately: crisp throttle response from low revs, no flat spot on acceleration, and a smooth engine note free of abnormal whistling. By contrast, a worn turbo shows itself through a gradual loss of power, blue or black exhaust smoke, excessive oil consumption, and sometimes an illuminated engine warning light. Fitting a new turbo to your A4 restores the performance you had from new and gives you reliable, day-to-day driving.

Compatibility with Audi A4 1.9 TDI engines

This new turbo is compatible with Audi A4 models fitted with the 1.9 TDI engine, in particular units identified by engine codes 1Z, AHH, AHU, AFN, AVG, ATJ, AJM, AVB and BKE, with an engine capacity of 1896 cm³. Before ordering, we strongly recommend checking the reference printed on the label of your original turbo, as several variants may have been fitted depending on the version and production period of your vehicle.

Warranty and delivery for this Audi A4 turbo

This new turbo is sold as a straightforward purchase: there is nothing to return, and your old turbo stays with you. This is a single delivery of the new turbo, with no return or collection of the old unit. The turbo is covered by a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over up to 10 instalments.

Advice before and after fitting on your A4

On 1.9 TDI engines, premature turbo failure is often caused by insufficient lubrication, poor-quality oil, or missed oil-change intervals. A clogged air filter or a damaged intercooler can also impair turbocharger performance. Before fitting, check the oil circuit, the condition of the hoses, and the cleanliness of the air intake. On first start-up, it is essential to prime the new turbo with oil to ensure immediate lubrication of the bearings and extend its service life.
