3 known faults with sources

Applies if: Only the 1.0 VVT-i three-cylinder (1KR-FE).

Water pump and clutch on the 1.0 VVT-i (1KR-FE)Cooling

Engine / equipment: 1.0 VVT-i three-cylinder (1KR-FE): Toyota Aygo, Yaris and iQ, Peugeot 107 and Citroën C1
Period mentioned: Approx. 2005–2011
Symptoms: Coolant loss with coloured residue next to the pump and rising temperature; a clutch that slips or squeals and hard gear changes earlier than normal.
Possible cause described: In the early years the water pump often failed after about three years of use; it was improved in 2009. The original 180 mm clutch was short-lived; a larger one was fitted from 2009 (a 190 mm alternative exists). The German Yaris II guide also lists faulty water pumps on the 1.0.
Check for the garage: Look for dried coolant residue under the pump and watch the level. Test the clutch pulling away on a hill; if it is replaced, ask for the improved version.
Cost cited in the source: Approx. €300–550 for the water pump (German used-car guide).A rough figure from the original database, not an up-to-date quote.

Applies if: Only the 1.33 Dual VVT-i (1NR-FE).

Oil consumption on the 1.33 Dual VVT-i (1NR-FE)Engine

Engine / equipment: 1.33 Dual VVT-i (1NR-FE): Yaris, iQ, Urban Cruiser, Auris and Verso-S
Period mentioned: Approx. 2008–2013
Symptoms: The oil level drops between services (more than half a litre per 1,000 km and up to a litre or more), usually from 150,000–200,000 km; bluish smoke.
Possible cause described: Owner forums blame low-friction piston rings that do not scrape the oil well; the fix was revised pistons and rings. The German Yaris II guide says it was only fully fixed in the next model.
Check for the garage: Check the history for oil top-ups or replaced pistons; measure consumption between two changes and check the spark plugs.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Applies if: Weak points of this model from inspections, breakdown statistics and recalls; anything specific to one engine is stated in the sheet.
