Coils, thermostat, valve collets and front axle on the Sandero IKnown weak points

Engine / equipment: Dacia Sandero I (petrol, LPG and diesel)
Period mentioned: 2008–2012
Symptoms: On the 1.2, coils and coolant loss from the thermostat housing; door locks, rust at the filler neck, an early-wearing clutch, ignition switch, starter and battery; at the roadworthiness test, suspension, steering, drive shafts, lights, brakes and exhaust mounts.
Possible cause described: Recalls: 1.2 valve collets on cars built 17/9 to 30/11/2010 (possible engine damage) and an ABS warning lamp that could fail (26/5–12/11/2008). The 1.5 dCi may need injectors and a turbo at high mileage.
Check for the garage: Check both campaigns by VIN; watch the coolant; check the front axle, brakes and exhaust.

Misfires and an idle that rises and falls on the 1.6 16V (K4M): coils and the stepper motorEngine

Engine / equipment: 1.6 16V (K4M), petrol or LPG: Dacia Logan I, Logan MCV I, Sandero I and Duster I
Period mentioned: 2006–2017
Symptoms: Backfiring and jerking: the engine misfires at certain revs because one or two coils stop sparking; or the idle rises and falls on its own.
Possible cause described: According to the owners who answer on DailyDriven, one Logan 1.6 16V lost two coils at different revs at 189,000 km, and on another the idle stepper motor made the engine “rev up and down on its own” at about 65,000 km; two other owners name the coils and the idle sensor as the parts that tend to fail. These are few owner reports, not statistics.
Check for the garage: Read the codes with an OBD reader to find which cylinder misfires and test by swapping the coil to another cylinder; check the spark plugs at the same time. If the idle hunts, clean or test the stepper motor.
Cost cited in the source: What DailyDriven owners paid: new coils and spark plugs, 324 lei (244 + 80); the stepper motor, about 500 lei. Amounts in lei from earlier years, not a current quote.A rough figure from the original database, not an up-to-date quote.
