EA888 Gen 3 1.8 TSI/TFSI (CJSA/CJSB/DAJA/DAJB)
"The third-generation 1.8 TSI/TFSI (2012-2020): 180 hp in the Audi A3 8V, Skoda Octavia III and Superb III, SEAT Leon III and VW Passat B8, 192 hp in the SEAT Ibiza Cupra and Polo GTI. Timing chain, port plus direct injection and an IHI turbo; it is not the oil-burning Gen 2 1.8 TSI of 2007-2012. The known weak point is the plastic water pump and thermostat housing, which leaks coolant (typically around 90,000 km) and was the subject of a US class-action settlement. Some engines use more oil than they should; check the level and the coolant reservoir before buying."
1.8 NA
"Simple 1.8-litre 8-valve petrol with single-point Mono-Motronic injection and hydraulic lifters, in the Golf III, Vento, Passat B3/B4, Polo 6N and Seat Ibiza, Cordoba and Toledo. Long-lived: an Auto Bild test car covered 261,724 km in seven years, and specialists quote about 300,000 km. Expect oil leaks from seals and the valve cover, tired lambda and coolant temperature sensors, and an unstable idle from a dirty or split throttle body. Keep the timing belt tensioned and changed on time: a slack belt can jump and wreck the engine."
