As the automotive market continues to diversify, consumers are faced with more and more car purchasing options, especially in the compact car market. In this regard, although the Peugeot 408 and Toyota Leiling are not as popular as Sylphy, Lavida and Sutar, their performance as the backbone of the compact car market is still remarkable. As can be seen from the sales of compact cars in December 2023, the Peugeot 408 sold 4,744 units, ranking 33rd; Toyota Levin sold 6,577 units, ranking 25th. There is not much difference between the two in terms of sales, and there is an overlap range in terms of ** and configuration. Below, we will analyze from the perspective of failure comparison to see who has a higher failure rate between Peugeot 408 and Toyota Leiling? What are the common failures of each of them?
The particle trap is clogged
In the 2023 Toyota Lelink Intelligent Electric Hybrid 1On the 8L model, the most common failure is the blockage of the particle trap. The specific phenomenon is manifested as: during the driving of the vehicle, the instrument appears "the exhaust filter is blocked, it is recommended to warm up the engine", and may be accompanied by the failure of high fuel consumption. The reason is that when the Toyota Leiling Shuangqing model is driving in the city, the engine working time is short, and the exhaust temperature is not yet to the level of burning exhaust gas particles, so it will accumulate in the particle trap and cause blockage. As for the solution, the manufacturer has not yet given a perfect answer. If you have such a problem, you can refer to the user manual, run more high-speed, and regenerate the particle trap. But in the end, it is a symptom rather than a cure, and I hope that the manufacturer will solve it as soon as possible.
The pump is squealing
Such failures are in Levin 1The 2T version is more common in the case of a "humming" noise in the engine compartment after the vehicle is started, and the sound becomes louder as the rpm increases, accompanied by occasional coolant leakage. The reason is that the internal bearings of the water pump are worn, and the water pump only needs to be removed and replaced. In addition, Lei Ling 1The 2T engine may also have the problem of abnormal noise of the generator, the fault phenomenon is basically the same as the water pump, the solution is to disassemble the generator and replace the internal bearings. In addition, 1The exhaust pipe bracket of 2T Lelink is easy to break, and there will be an abnormal sound of "bang" or "boom" when stepping on the accelerator after breaking, just replace the bracket with an improved one.
Intelligent boarding and starting system failures
The fault is manifested as: when the vehicle is ready to start, the instrument appears "intelligent boarding and starting system failure, please refer to the user manual" prompt, and the vehicle will not start. There are generally two common reasons, one is that the start switch is damaged, you can choose to disassemble it, adjust and clean the internal contacts, and it can be restored to normal, of course, you can also choose to replace the switch directly; The second is that the small battery is damaged, it can be replaced, pay attention to try not to cut off the power during the replacement process, so as not to lose data. In addition to the above faults, the common faults of Leiling are the car machine jamming and gearbox stuttering.
The engine burns oil
This failure is prone to occur on the previous Peugeot 408 models of the 2018 model year, and the engine involved has 12t、1.6t and 18l。The fault phenomenon is manifested as: after the vehicle travels 5,000 kilometers, the engine oil is reduced by about 1L, and the more serious situation will also be 1,000 kilometers of oil loss. The main cause is piston ring stagnation, aging valve seal, or waste valve damage, etc., and only need to be replaced. For the slight oil burning fault of the model, it is recommended to deal with it as soon as possible, if it is not treated for a long time, and a trip to forget to replenish the oil, it may lead to engine cylinder and other failures, maintenance costs will also increase significantly. In the ** model, the Peugeot 408 has improved the piston rings, and the number of oil return holes has been increased from the original 16 to 48, so there is almost no problem of burning oil.
The gearbox radiator is damaged
This fault is often seen on Peugeot 408 models equipped with an Aisin 6AT gearbox, codenamed TF-71SC. The specific fault phenomenon is manifested as: during the driving of the vehicle, the gearbox fault light lights up for early warning, and the control unit is stored in the control unit "torque converter slippage" or "clutch brake slippage" and other faults**, and may be accompanied by gearbox frustration, vehicle speed is limited to 60km h, etc. The reason for this is a perforation inside the transmission heat exchanger (radiator), which causes coolant to enter the transmission and fluid mix. The solution was to replace the radiator with a new one and clean the gearbox. Note that this fault is easy to judge as damage to the cylinder gasket, so do not rashly lift the cylinder head, so as not to lose more than you gain. In addition, the fault has been improved in the ** model, and the old car owner can do maintenance reference.
The power management module is damaged
The power management module, as the name suggests, is a module that manages and distributes power to the whole vehicle electrical appliances. When it is damaged, the vehicle instrument or the central control screen will appear "battery charging failure, please stop" warning prompt, and the instrument will light up multiple fault lights at the same time, and in serious cases, it will also cause the vehicle to fail to start. The reason for this is that the power management module is damaged internally, which can be disassembled for repair or replaced. If you encounter this outdoors, you can try to start the vehicle while tapping the power management module for emergency treatment. In addition, the Peugeot 408 is also prone to abnormal water pump leakage, compressor abnormal noise, thermostat leakage damage, timing belt wear and clogging the oil passage (12t) and other failures.
Overall, the Peugeot 408 and the Toyota Levin are not much different in terms of failures, but the distribution of systems is different. The Peugeot 408 has most engine failures, but they are all minor problems, and if there are major problems, such as design flaws, they have also been optimized in subsequent models; The faults of Toyota Levin are mainly concentrated in the hybrid version of gasoline and electricity, so there are many faults in the electrical system.
