How a good turbo transforms your Audi A4
On an Audi A4 fitted with the 2.0 TDI engine, a turbo in perfect working order makes itself felt from the very first miles: throttle response becomes sharp again, the low-rev flat spot disappears, and mid-range pull regains its smoothness — particularly when overtaking or driving under load on the motorway. A worn turbo, by contrast, shows up as a noticeable loss of power, an unusual whistling noise, exhaust smoke, or an illuminated engine warning light. Fitting a new turbo restores the vehicle's original performance and prevents premature engine wear caused by a failing boost system.
Compatibility with 2.0 TDI engines in the Audi A4
This new turbo is compatible with reference 04L253019A, intended for Audi A4 models fitted with the 2.0 TDI 136 hp and 2.0 TDI 150 hp engines, associated with engine codes CAGB, CJCB, CSUA and CSUB. Before placing an order, we recommend checking the reference printed on the label of your old turbo or in your vehicle's technical documentation, to confirm an exact match with your engine.
Warranty and delivery for this Audi A4 turbo
This new turbo is sold as a straightforward purchase: there is no old unit to return — your old turbo stays with you. A single delivery is made, that of the new turbo. The turbo comes with a 12-month parts warranty, subject to fitting by a qualified professional. Payment for your order can be spread over several instalments, in up to 10 instalments.
Advice before fitting on your 2.0 TDI
The service life of a turbo on this engine depends heavily on the quality and regularity of oil changes, as degraded oil or an insufficient oil level causes rapid wear of the bearings. Remember also to check the condition of the air filter and intercooler, as well as the integrity of the boost hoses — components that are often overlooked and can lead to another failure. Before starting the engine, it is essential to prime the turbo by pouring a little fresh oil into the dedicated oil feed, and to ensure that the oil circuit and air intake are free from any blockage or leak.
