New Audi TT Turbo – Ref. 785448-5005S

Signs of a worn turbo on the Audi TT 2.0 TDI 170

On the Audi TT fitted with the 2.0 TDI 170 engine, a failing turbocharger typically makes itself known through a gradual loss of power under acceleration, an unusual whistling noise on the air intake side, thick blue or black exhaust smoke, and sometimes an engine warning light triggered by abnormal boost pressure detected by the ECU. Higher-than-usual oil consumption is also a common sign of excessive play in the turbo of this sporting coupé.

Advice before and after fitting on the 2.0 TDI

Before installing this new turbo on your Audi TT, carefully check the oil circuit (hoses, return line, no blockages), the cleanliness of the air intake and the condition of the air filter, as well as the intercooler for any leaks or fouling. A full oil change using a quality oil suited to the TDI engine is essential, as insufficient lubrication or a contaminated oil circuit are common causes of premature failure on these engines. On first start-up, prime the turbo with oil before starting the engine, then drive gently for the first few kilometres to allow the rotating assembly to bed in properly.
