Helped by the diesel craze, the 1.2 PureTech was an actual industrial success. Especially in its turbocharged model (110 and 130 hp), which mixes an excellent degree of efficiency with a relatively affordable urge for food. Since its introduction in 2013, this three-cylinder (code EB2) has been broadly used within the PSA group (Citroën, DS, Opel and Peugeot). But its reliability is much from flawless. The argument boils right down to inside technical notes despatched to sellers compiling an inventory of main design flaws. We provide you with technical options and the corresponding manufacturing vary. Without forgetting the potential help that varies from one buyer to a different in line with completely different parameters (automobile age and mileage, respect of upkeep intervals…).

Accelerated timing belt put on

What is the issue?

It is the defects that result in buyer dissatisfaction resulting from restore prices. The timing belt, known as moist as a result of it’s submerged within the crankcase, wears out prematurely. An issue particularly current in automobiles that drive little. In query, the phenomenon of oil dilution: gasoline droplets, which move alongside the cylinder wall within the decrease crankcase, contaminate this lubricant. It then turns into extra abrasive, which accelerates belt put on with key engine failure dangers.

Other collateral harm is feasible. Residue from the belt can get into the vacuum pump of the brake booster system and clog it. Consequences? A stiff brake pedal and lengthy stopping distance. On the opposite hand, the filters of the oil pump strainer, in addition to the variable timing solenoid valve, can even develop into clogged, a fault that’s indicated by the engine oil stress warning gentle approaching.

What is the technical resolution?

An enormous recall was launched in January 2021 for 220,000 automobiles manufactured between 2013 and 2017. But, opposite to what some homeowners believed, it was solely geared toward correcting problems with the brake help and never with the distribution. A technical be aware from July 2022 signifies that vacuum pump clogging should still happen in later 2017 fashions. In the occasion that the braking energy or engine oil stress warning gentle illuminates, workshops should perform plenty of checks. They verify the situation of the vacuum pump oil filter, the oil pump strainer, the 2 variable timing solenoid valve filters and the n°4 camshaft bearing. Depending on the outcomes of this take a look at, cleansing the oil pump strainer and variable timing solenoid valve filters will typically be ample. But typically will probably be mandatory to switch the vacuum pump, the oil pump and its solenoid valve, the decrease oil sump and even the timing belt. Even all the engine in some instances.

Timing belt control 1.2 Puretech

Workshops now verify belt width at every upkeep and suggest an annual assessment for youthful riders (vital upkeep).

Dr

The belt alternative interval has additionally been modified. It went from 10 years or 175,000 km to six years or 100,000 km. With this belt width management which should now be carried out by the workshop at each periodic overhaul. Rigorous upkeep with an oil change yearly is beneficial for many who drive lower than 15,000 km per 12 months and whose every day journey is lower than 10 km.

Which automobiles are affected?

The design of the belt has been revised a number of instances since 2013. The newest growth date is June 2022. Vehicles launched this summer time will due to this fact be theoretically safer, nevertheless it stays to be verified whether or not the adjustments bear fruit. This EB engine’s third-generation timing chain will keep away from this pitfall. But it isn’t but available on the market and will likely be reserved for gentle hybridization variations geared up with the brand new double-clutch gearbox developed with the punch powertrain.

What help?

Outside the guarantee interval, full protection of elements and labor is feasible if the automobile is lower than 6 years previous or lower than 100,000 kilometers resulting from untimely put on of the belt, whichever comes first. Attention, to keep away from a rejection, the upkeep plan have to be strictly adopted. After-sales service doesn’t tolerate the slightest overrun.

Self-ignition (rumble) earlier than spark

What is the issue?

While driving, it’s possible you’ll expertise jerking or jerking when the engine diagnostic warning gentle comes on. This is the results of a self-ignition phenomenon that happens earlier than the spark of the plug, known as “rumble” in English. This downside is said to cylinder head sticking.

What is the technical resolution?

Workshops should perform quite a few checks reminiscent of cylinder compression, presence of oil within the air consumption or fouling of the consumption valve. Depending on the outcomes, they could then change the engine oil, oil separator, air/air warmth exchanger, gasoline tank, injectors or canister absorber. It can also be deliberate to wash the cylinder head consumption ducts and in essentially the most extreme case even change the engine.

Which automobiles are affected?

All the potential ones are created as a result of no mounted resolution is given within the manufacturing facility but

What help?

Partial protection is feasible as much as 5 years or 150,000 km. Attention, when you have exceeded 3,000 km or greater than 3 months of upkeep, will probably be rejected. It’s the identical story with non-adherence to beneficial oil high quality, and workshops are even instructed to verify the compatibility of injectors and the extent of ethanol within the tank. So the danger of utilizing E85 is at your expense.

Excessive use of oil

What is the issue?

Owner complains of getting to prime up the oil continuously resulting from defective splits. This downside coexists with problems with the oil vapor separator, which is why the engine oil degree warning gentle can come on lower than 6,000 km after the utmost degree adjustment.

What is the technical resolution?

In all instances, a verify for the absence of leaks, then an oil filling is carried out. The buyer should drive the automotive to gauge the fee. If the issue comes from the break up, it is a pure and easy change to the engine that is profiled. On the opposite hand, if the oil vapor separator is in query, its alternative is ample.

Which automobiles are affected?

In the absence of a manufacturing facility resolution for the second, all manufacturing might doubtlessly be affected by the segmentation downside. The oil vapor separator was modified in November 2021.

What help?

If this extreme oil consumption is licensed and maintained, full protection of elements and labor prices is feasible as much as 100,000 km or 5 years. Partial protection, this time restricted to elements, is then potential as much as 8 years or 150,000 km.

Engine ECU

What is the issue?

The diagnostic indicator lights up.

What is the technical resolution?

If fault code P1337, P1338 or P1339 is current, the engine management ECU have to be reprogrammed.

Which automobiles are affected?

All Euro 6.3 (Euro 6.D) fashions till 01/03/2021. Since this date, the software program has had an evolution.

What help?

Manufacturers present full protection of the automobile as much as 5 years, with no mileage restrict.

Problems with out scheduled help

Energy loss

This downside, typically accompanied by a diagnostic warning gentle, is often attributable to a defective excessive stress gasoline pump In the workshop, the technician should learn the fault codes. Then they often must verify the low stress gasoline provide circuit or the excessive stress pump provide as nicely. earlier than changing the latter if mandatory. In complete, the intervention required 40 to 50 minutes of labor. The half was modified on the manufacturing facility in May 2015, then in July 2021 to attempt to right the state of affairs in line with the model of the engine.

High stress pumps will not be the one reason behind this warning gentle. Depending on the manufacturing vary and the fault code detected by the diagnostic case, 4 different problems are detected:

  • As of June 2015: Oil pump solenoid valve. Its alternative requires about 1 hour and 20 minutes of labor
  • As of August 2017: Engine Speed ​​Sensor. Its alternative takes about 1 hour and quarter-hour
  • Across all the manufacturing vary: cylinder head bores. After checking the fault codes, workshops should verify the engine quantity and the presence of engine coolant or spark plug wells attributable to cylinder head perforation. If these checks result in a cylinder head alternative, you have to sadly count on a reasonably hefty invoice. This heavy and delicate intervention truly requires about 7 hours of labor in line with the official scale.
  • Until February 2021: Spark plugs. From this date, a brand new reference has been mounted.
