Lambda sensor, 1.2 TCe, EDC gearbox and campaigns on the Duster IKnown weak points

Engine / equipment: Dacia Duster I (1.6 16V, LPG, 1.2 TCe and dCi)
Period mentioned: 2010–2017
Symptoms: On the 1.6 16V, lambda sensors and sometimes the catalytic converter; on the 1.2 TCe, a chain with a risk of serious failure and oil consumption; a fuel gauge stuck at half, central locking, air conditioning, cracking windscreens; rust on early Indian-built cars; a jerky EDC gearbox.
Possible cause described: Recalls: rear brake lines on 2010–2011 4x4s that could break in deep snow, trailer wiring (8/12/2016–13/6/2017), engine-ECU software (stop-start) and a horn that could trigger the airbag (2017).
Check for the garage: Check the campaigns by VIN; on the 1.2 TCe, listen to the chain and measure consumption; check the underbody and fuel gauge.

Accessory belt that slips or breaks on the Dacia 1.6 16V (Logan and Duster up to 2013)Engine

Engine / equipment: 1.6 16V petrol (K4M) with air conditioning and power steering: Dacia Logan and Duster built in Pitești
Period mentioned: 2010–2013
Symptoms: The accessory belt slips, wears early together with its roller or breaks; if it breaks, power steering and alternator charging are lost.
Possible cause described: The alternator pulley is a fixed wheel and does not absorb the engine's rotational irregularities, so the belt suffers. In February 2015 Dacia opened a curative workshop action for the Logan and Duster 1.6 16V built in Pitești up to 27/4/2013 (6,344 cars in France): it replaces the alternator and the accessory belt kit and, in extreme cases, the engine.
Check for the garage: Check the accessory belt and the tensioner roller and whether the alternator has a fixed pulley. If the belt slips or is cracked, replace it with the roller; ask Dacia by VIN whether the car was in the 2015 action. If the belt breaks while driving, stop: without it the battery is not charged.
