Character
F9Q (2005-2012, Euro 4/5)
"Later 1.9 dCi (Bosch CP3 common rail, Euro 4 and 5) in the Megane II/III, Scenic II/III, Laguna II and Suzuki Grand Vitara. Much better than the 2000-2005 engines: the connecting-rod bearing problem is gone and turbo faults were fixed by 2008. The weak point is the injectors - a leaking injector seal can damage the engine - plus EGR clogging. Timing belt."
D4F
"Renault 1.2 petrol for small cars (Twingo, Clio, Kangoo, Modus, Dacia Logan/Sandero): the 8V D7F from 1996, the 16V D4F from 2000. Simple and long-lived. It has a timing belt, not a chain - change it on time because a broken belt bends the valves. Throttle-body fouling causes idle problems; D4F engines built Sep-Nov 2010 had a valve-cotter recall."
