F9Q (2005-2012, Euro 4/5)
Renault · F9Q 1.9 dCi (2005-2012)
2005–2012
"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."

Known Issues 4
Injector or injector-seal leak
▸Diesel smell, ticking or blow-by noise from the head, hard starting, rough idle, smoke
Injection faults are the most reported problem of the 130 hp 1.9 dCi and affect every generation, often through a leaking injector seal. Left alone, a leak can lead to engine failure.
No Greek-specific data found.
Turbocharger faults (to 2008)
▸Loss of power, limp mode, whistling, boost fault codes
Turbo trouble continued on the 130 hp engine until 2008 and was then corrected; many cases are a split hose, a seal or the pressure sensor rather than the turbo itself. The turbo does not tolerate low or old oil.
Late oil changes shorten turbo life. No Greek-specific data found.
EGR valve clogging
▸Loss of power, limp mode, engine warning light
The EGR valve clogs with soot, mostly on cars used in town.
City driving and short trips speed up clogging. No Greek-specific data found.
Timing belt (replace on schedule)
▸Preventive only
The camshaft is driven by a timing belt. Change it on schedule and check the accessory belt too: if the accessory belt breaks it can fall into the timing drive and force a major repair.
No Greek-specific data found.
