New Audi A4 Turbo – Ref. 818987-5001S

Symptoms of a failing turbo on the Audi A4 2.0 TDI 177 CV

On the Audi A4 fitted with the 2.0 TDI 177 CV engine, a turbocharger that is nearing the end of its life often makes itself known through a gradual loss of power under acceleration, an unusual whistling noise from the intake or exhaust side, thick blue or black smoke from the exhaust, and sometimes the engine warning light coming on alongside a boost-related fault code. Some drivers also notice excessive engine oil consumption or an unstable idle, which are signs that the turbo's bearings or seals are beginning to let oil through.

Advice before fitting on your A4

Before installing this turbo, check the condition of the oil circuit (hoses, feed and return lines), the cleanliness of the air filter, and the integrity of the intercooler, as a fault in any of these components can cause premature failure of the new unit. A full oil change using oil that meets the manufacturer's specifications is essential, as is priming the oil circuit before the first start-up to ensure the bearings are lubricated immediately. Allowing the engine to warm up and cool down gradually will also help extend the life of the turbocharger.

• Check oil hoses and connections before fitting
• Inspect the air filter and air intake
• Prime the oil circuit before starting the engine
• Drive gently, especially after a hard run
