Renault 1.0 SCe (B4D)Timing chain
Chain-driven timing: no documented pattern of faults on the 1.0 SCe (B4D)
Unlike engines with a timing belt, the 1.0 SCe barely records any mentions of the timing in the sources consulted: 1 case out of 117 combined reviews of the Sandero II, the Logan II and the Twingo III, with no further detail. It is not a fault that we can document as a pattern on this engine.[1][2][3]
Why this rating?
Low severity: A nuisance or wear. It does not immobilise the car or damage other parts.
Frequency rare: Fiches-auto.fr records only 1 mention of "timing" out of 117 combined reviews of the Dacia Sandero II (1 of 20), the Dacia Logan II (0 of 7) and the Renault Twingo III (0 of 86 on SCe 70, 0 of 4 on SCe 75), with no additional detail on that single mention. There is therefore no documented pattern of timing faults for this engine in the sources consulted.[1][2][3]

What owners say
Frequently asked questions
Does the 1.0 SCe timing chain cause problems?
Not according to the sources consulted: there is only 1 mention of the timing out of 117 combined reviews of the three cars reviewed, with no identifiable pattern.[1][2][3]
Does it have a timing chain or a timing belt?
Our sources do not explicitly confirm it for this particular engine; no reliability report mentions a timing belt replacement for the 1.0 SCe, unlike what does happen with other, older naturally aspirated engines in the Dacia/Renault range.[1]
Does it have to be changed at a set mileage, like a belt?
We have not found a published preventive replacement interval for this engine in the sources consulted.[1]
What can you do now?
We will put you in touch with a partner only if you authorise it in the form.
Other 1.0 SCe (B4D) faults
- Medium severityFrequency: OccasionalClutchClutch that slips or judders, especially when coldThe 1.0 SCe can have a clutch that slips or judders, especially with a cold engine. It is the issue that recurs most in the sources consulted, documented independently on the Sandero II, the Logan II and the Twingo III, without being described as a fault that damages the engine.
- Medium severityFrequency: OccasionalElectronicsJerking, rough idle or warning light from sensors and ignition coilsThe 1.0 SCe can jerk, run unevenly or light up the engine fault warning light because of sensor faults (lambda sensor), ignition coils or injection management. It is a recurring but minority issue in the sources consulted, unrelated to a mechanical problem with the engine block.
- Low severityFrequency: OccasionalLubricationHigher-than-normal oil consumption (especially on the Dacia Sandero II)The Dacia Sandero II with the 1.0 SCe can use more oil than normal, with one documented case of 750 ml every 5,000 km; on the Dacia Logan II and the Renault Twingo III with the same engine this problem is not described in a comparable proportion.
More faults with the timing chain on other engines and cars
- Critical severityFrequency: Very frequent1.5 BlueHDiWear and breakage of the 7 mm chain between the camshaftsIn 1.5 BlueHDi engines built between October 2017 and January 2023, the 7 mm chain linking the camshafts can stretch and break, causing serious engine damage. Stellantis has recalled them and covers the fault for 10 years or 240,000 km.Repair (garage): €730–€820
- Critical severityFrequency: Very frequent1.2 and 1.4 TSITiming chain stretch and tensioner failure (EA111)On the 1.2 and 1.4 TSI EA111 (2006-2015) the chain can stretch and the tensioner fall short; if the chain jumps a tooth, the valves hit the pistons. Volkswagen admitted the defect in 2012 and revised the chain and tensioner between 2010 and 2011.Repair (garage): €700–€1,400Appears at around 30,000 km
- Critical severityFrequency: Very frequentBMW N47Rear timing chain stretch and breakageYes: the N47 has its timing chain at the rear of the engine, next to the gearbox, and on a very high proportion of units, especially those built between 2007 and 2009, it stretches or breaks prematurely because of an inadequate tensioner, with a risk of destroying the engine.Repair (garage): €1,590–€3,000Appears at around 50,000 km
- Critical severityFrequency: Very frequentOM651Timing chain stretch and tensioner failureYes: the OM651 timing chain can stretch prematurely, above all on units built up to 2013, and in 2014-2015 Mercedes-Benz recalled around 114,000 vehicles in Germany over a defective sealing ring in the tensioner. A metallic rattle on a cold start is the first sign.Repair (garage): €2,000–€3,500Appears at around 120,000 km
- Critical severityFrequency: Very frequent2.0 Ingenium diéselTiming chain stretchYes: the timing chain on the 2.0 Ingenium diesel can slip or stretch prematurely and put the engine out of time, with a risk of serious failure. It is documented on the Evoque, Discovery Sport, XE, E-Pace and F-Pace, with engine failures between 90,000 and 130,000 km in several owner reports.Repair (garage): €4,000–€7,000Appears at around 90,000 km
- Critical severityFrequency: Common1.3 MultijetTiming chain stretch and tensioner failureYes: the timing chain's hydraulic tensioner can lose pressure and let the chain slacken; if it skips teeth or breaks, it can destroy the engine. It is a documented problem on Fiat, Opel, Suzuki and Ford cars with this engine, mainly linked to long oil change intervals.Repair (garage): €350–€550Appears at around 70,000 km
