New SEAT Altea Turbo – Ref. 785448-5005S

Diagnosing the turbo on your SEAT Altea before replacement

Before considering a turbo replacement on your SEAT Altea fitted with the 2.0 TDI 170 engine, it is essential to confirm that the turbo is actually at fault. Checking the engine oil level and quality, visually inspecting the intake and exhaust hoses for leaks, and verifying that the exhaust gas recirculation valve is working correctly will often rule out other causes of power loss or smoke. A diagnostic tool can also read fault codes related to boost pressure to guide the diagnosis before you order the part.

Fitting advice for the CFFA/CFFB engine

On these 2.0 TDI units, turbo failure is often caused by insufficient lubrication, poor-quality oil or neglected oil changes, as well as a clogged air filter or a damaged intercooler. Before fitting, check the oil circuit, the intake hoses and the air intake to prevent contamination of the new turbo. On first start-up, remember to prime the oil circuit to ensure immediate lubrication of the turbocharger.
