Character
1NR-FE
"The 1.33 petrol in the Yaris XP90/XP130, Auris and Corolla E150/E180, iQ, Urban Cruiser and Verso-S. Chain-driven, port injection, no turbo. German and French used-car data rate it durable, but it is known for oil consumption that grows with mileage, and engines run low on oil can fail. Check the dipstick and the service history."
1KR-FE
"Toyota three-cylinder in the Aygo, Citroen C1, Peugeot 107/108 and Yaris. Simple, light and cheap to run with a maintenance-free chain. Watch two things: the water pump on 2005-2009 cars (an uprated pump came in 2009) and the oil level, which owners report dropping on some engines."
