Recently, there are more and more requirements for environmental and safety. As a result, the number of sensors and aggregates installed. This eventually cause a large number of breakdowns. For example, after a while, Renault Logan may begin. In this case, you can try to contact the service center or by the main features yourself to eliminate the malfunction.
We will try to consider frequently encountered problems and basic ways to eliminate them in this article in more detail. Almost all of them are related to the fact that Renault Logan is bad to start cold.
If the Renault Logan engine does not start the starter twist, but the car constantly stalls, then there are several main causes of faults:
- Fuel regulator fault
- Candles do not produce a spark, the problem with the coils
- Incorrect installation of timing marks, peroxarcation of the operation phases of ignition
- The injection of the throttle, which is responsible for the supply of air mixture
- Failure of immobilizer, loss of communication with chip
- Clogging of fuel injectors, deterioration of the quality of fuel spraying
- Fuel filter pollution
Diagnostics
To resolve the fault required to begin to determine exactly at what level the system fails. This requires the diagnosis of components, during which some features should be taken into account:
- If the pressure regulator failed, then it is necessary to immediately change this component to the new one. To do this, you first need to disconnect the fuel reverse hose, then turn on the ignition. If fuel goes out of the hose, this will indicate the failure of the regulator. If this problem occurred while driving, on the highway, then you need to pass the tube or drown out, so that you can get to the nearest maintenance station
- When the spark disappears, it can also cause serious interruptions in the engine. In this case, you need to use the special candlestone, with which all the candles are twisted. It is necessary to carefully inspect the electrodes and tips of high-voltage wires. If there are traces of Nagar, then most likely they are faulty. To quickly check, you can ask the assistant to rotate the ignition key for a few seconds so that the starter checked a little but the engine does not "grab". At this time, tediously connect the candle to the high-voltage wire and trace the appearance of the spark. If it is absent, then you can get to the place of repair, but you should have accurate diagnostics of the node as soon as possible and its replacement. It is important to remember that high-voltage wires represent a greater danger and to diagnose and work with them with extreme caution.
- Incorrectly set marks of the phases of the gas distribution mechanism lead to the fact that the engine begins to work with strong interruptions and jumps of revolutions. It will also be accompanied by strong cotton from the exhaust manifold. Malfunction can be eliminated only if there are special equipment. It is not recommended to try to independently adjust the GHR phases if the breakage occurred on the road, it should only do specialists for a hundred.
- Incorrect adjustment of the throttle or its contamination can be detected in several ways. The most effective is the disconnection of the air nozzle and inspection of the valve state, search for defects on the walls of the case and traces of production.
- If the Renault Logan does not start or immediately after starting it stalls, then you need to look at the display of the immobilizer lamp, which is located on the instrument panel. The reason may be in loss of communication with the chip. In this case, it may be necessary to reprogram the key, so during long journeys it is always better to have a working duplicate with you to be able to start a car.

Essence of the question: on the cold start, and Renault Logan does not start on the hot.
Bought Logan from the former owner, a car from Phase 1. The mileage is small, but lately the defect has been manifested: when you start "on the cold" everything works, but with a "hot start" the motor does not start. It turns out, it is necessary to wait 5-6 minutes, until the engine cools. The starter twists, but the motor "does not pick up". Previously, this was not.
Nevertheless, why my Renault Logan does not start, as it should?
Main reasons
The reason for the defect specified in the question may be one - a faulty DPT sensor. This sensor itself will need to be replaced, but you can first spend one check.
Cooling fluid temperature sensor
The Following Two Tabs Change Content Below.
I own Renault Megan 2 car, before that there were Citroen and Peugeot. I work in the service zone of the dealership center, so I know the device of the car "from and to". You can always contact me for advice.
So, we will model the problem situation:
- We start "on the cold", heating the motor;
- It is necessary to achieve that the motor stops start. Wait 5 minutes at the same time;
- If the engine cannot be started, open the hood and turn off the Dzhtoh sensor. Immediately try to start.
Conclusions: If the motor at "step 3" started again, it means that the reason is in a faulty sensor. Further comments are superfluous.
Another probable reason
Connector that delivers problems
Turn off the connector when the ignition is turned off. Do not forget to collect everything, as it was.
The B8 line in the R212 connector is associated with the ignition lock. When it breaks it, the starter will work, but the engine start is blocked.
Consider the reasons when Renault Logan does not start "on the cold". They look trite:
- Overlook or discharged battery;
- Water got into the tank;
- Faulty fuel pump;
- Etc.
But there is another reason characteristic only for the Logan family.
Defect program of the ECU on the engine with Euro-3
If the engine complies with Euro-3 standards, it means that the controller of the ECU may need to replace the firmware. At one time was reviewed, but not everyone responded to Renault request.
The only "letter of happiness" from Renault
Sedany Logan, who are subject to review, were produced from December 2007 to accurate before restyling. We are talking about the transition to "Phase 2" (to the norms of Euro-4).

In the article, consider possible malfunctions that may occur during the operation of the Renault / Dacia Sandero car.
The engine will not start
Running the engine with fuel injection system is the same at any ambient air and fluid temperatures in the engine cooling system.
To start the engine, you only need to turn on the starter, without pressing the gas pedal, and the system itself is adjusted for the necessary fuel supply parameters and the ignition advance.
If the engine from three attempts did not start it:
Open the hood by pulling the drive handle on yourself
Measure the dipstick level of oil
In the engine K4M, the oil level should be between the upper and lower boundary of the shaded plot
In the engine K7J and K7M - between the bottom and the top marks on the dipstick
Check the coolant level
It should be between MIN and MAX marks on an expansion tank.
We inspect the engine. We pay attention to the drums of gasoline, oil and coolant.
Check the integrity of the wiring.
We check the landing of the pads of the wiring harnesses in the connectors of the ignition coils.
After inspection of the engine and systems, we once try to start the engine.
If the engine from the first attempt did not start, then press the gas pedal until it stops and turn on the starter for two to three seconds.
In this mode, cylinders are blocked, the fuel is not fed through the nozzles and the voltage is not fed to the spark plugs.
After the cylinder is purging, we try to start the engine as usual, without pressing the gas pedal.
If nevertheless, the engine did not start, then:
Power system does not work;
The ignition system does not work;
Starting system does not work.
Faults start
Starter does not turn on.
The reason may be violation of contacts and compounds.
Open or short circuit in the starter inclusion circuits, a traction relay fault.
If clicks are kept when the starter is turned on, then the reason in the discharged battery is oxidized or weak contacts on the battery or starter.
Also, the cause can be a malfunction of the holding relay winding.
If the starter turns on, but anchor either does not rotate, or rotates slowly.
The reason is the battery is discharged, the contact connections are impaired, the contacts of the traction relay are burned, the collector is dirty or brushes, interstetic or short circuit in the starter winding.
If the starter turns on, his anchor rotates, but the flywheel is immobile.
The reason can be the weakening of the starter attachment to the clutch card, damage to the teeth flywheel or drive gear, slipping the clutch of the free move drive, lever breakage, leash ring or the starter buffer spring springs.
If the starter does not turn off after the engine start.
The reason is the fault of the clutch of the free stroke of the starter, sintering contacts of the traction relay. If such a malfunction occurs, you need to stop the engine immediately.
Good evening. Suddenly ceased Renault Sandrera 2010 release. Mileage 56 thousand. The problem happened when the wife went to take children from the cottage in the Yaroslavl region. From Moscow to the summer, the wife reached normally. The time on the way was 7 hours. The next day, the wife gathered to go back to Moscow, but the car would not start. Put another battery - started. After the battery was removed from the machine, stalled. Loaded the battery at the neighbor and went to Moscow. The time on the way was 4 hours. Machine reached. The question of what could be a malfunction? Old battery? Generator? Is it possible to remove the battery on the siders when the motor is running?

good day.
it is not very desirable to shoot on the working machine of the battery (with the exception of cars where there are no electronics such as a penny old Muscovites) occurs in an electrical system and can burn some sensor, it is best to divide with wires.
if I understood correctly does not start it, it turns badly or does not twist the starter.
the reason that the car was not started by the village of Akb.
but why he sat down the reasons for two either in disrepair the battery is either charged.
when a car driving a warning lamp burns "Akb" on the tidy signaling that there is no charge?
first of all, when the battery installed on the car, measure the voltage on the terminals, it should be around 12.5 - 12.8 volts, then start the car and also measure the voltage at the terminals should be more about 13.8-14.5 volts, (fuse The voltage should increase slightly) This indicates that the working generator. Also, turn on the maximum all the electrotransmitters on terminals voltage should not be below 12.8 volts.
if the generator is worked out by the wines of the entire ABB.
