We all know that now the car is generally used electronic anti-theft system. In the control of the engine ignition, the use of electronic answering machine keys. It consists of the ignition key of the built-in electronic chip and the reading coil, the transceiver component, the control module and the engine electronic control module located on the ignition switch. It works by the owner of the key into the ignition switch and turn to the ON position, the jack of the power supply coil through the car key programmer electromagnetic induction way for the key power supply, and then the key inside the electronic remote control module to send a key signal to the anti-theft system Control unit, anti-theft system electronic control unit to receive the signal after the code with the previous storage is the same. If the same, to the engine electronic control unit issued to enter the normal working procedures of the instructions, the engine starts normally. If not the same, to the engine electronic control unit to stop the normal operation of the program instructions, the engine immediately after the start of 2s flame.

Keyless start system is now more and more common in the car, the owner only need to bring the key in the body, you can press the button a key to start the car, a large extent to enhance the convenience of the car. Its working principle and the above electronic response xhorse vvdi mb bga tool car keys almost, but its signal is transmitted through the wireless and receive, and its key signal is more complicated. In the back of a key to start the button, there is also a reading coil, its role and the key to start the model is the same.

The above two ways, not the engine after the start button is useless. In the car use process, the reading coil will continue to send a signal to communicate with the car key to confirm the legitimacy of the key. If you find the key is not in the car, will be prompted in the instrument, and issued a warning tone. In this process, due to the role of electromagnetic induction, the CGDI Progreading coil will heat, the heat will be transferred to the keyhole inserted in the keyhole, the key will be hot; and keyless entry and start the system due to the car keys The receiving and transmitting signals, will produce a certain amount of heat, as we use the phone when the phone will heat the same. This is the root cause of the car keys and keyhole fever!

Selon la description du client, il y a un mois, la voiture dans la station d'essence accidentellement ajouté l'essence, mais en raison de la découverte en temps opportun, n'a pas été effectuée pour démarrer le fonctionnement du moteur, et la voiture traîné à d'autres ateliers de réparation, , Le système d'huile a été nettoyé et remplacé par deux injecteurs. A propos de la conduite normale pendant environ un mois, le moteur cardiagtool ne peut pas démarrer, traîné dans ma boutique pour la maintenance. Après avoir reçu la voiture, connectez d'abord l'ordinateur de diagnostic VAS6150B pour lire le code d'erreur 01 du système moteur.

Sur la base de l'expérience passée, il est décidé de vérifier si le système haute pression comporte des copeaux métalliques. (N276), le capteur de pression de carburant (G247), le rail d'huile haute pression, la poussière, indiquant qu'il n'y a pas d'usure sur la route. Et puis a commencé à vérifier l'huile, desserrer la tuyauterie sur le rail d'huile, démarrer le fonctionnement du moteur et a trouvé une sortie de diesel, indiquant une basse pression, la pompe haute pression n'est pas un gros problème. Au cours de l'opération, on a constaté que la quantité d'huile renvoyée dans le tuyau de retour d'huile était relativement grande, de sorte qu'il y avait un problème avec la buse. Directement à la buse enlevée pour vérifier, connecté à la rampe d'huile, ouvrez le commutateur d'allumage trouvé qu'il ya deux réservoirs de la buse n'est pas de carburant. Après avoir discuté avec le propriétaire, a décidé de remplacer les six injecteurs de carburant.Xhorse Condor XC-002buse, avec le diagnostic de l'ordinateur dans la requête de défaut 01 guide de sélection du moteur pour correspondre, après le test, le moteur a commencé en douceur, et n'a pas trouvé d'autres anomalies, donc la livraison. Une semaine plus tard, a reçu un téléphone client, a déclaré que le moteur a commencé à secouer le matin, l'après-midi prêt à conduire à l'inspection de la boutique, commencer après la montée moteur soudainement éteint, puis ne démarre plus. Après avoir reçu le téléphone, j'ai magasiné immédiatement envoyé un véhicule de sauvetage pour faire glisser la voiture. Vérifiez à nouveau, avec un ordinateur pour lire 01 code de défaut du moteur est encore "la pression du système de rail d'huile de carburant est trop faible." Après l'inspection et l'analyse, enlever encore une fois la buse et le test d'injection de carburant, comme illustré à la figure 2. Le test a révélé que six injecteurs seulement une injection de carburant! Bien que la qualité de la dernière nouvelle buse pour certains doutes,

Selon le code de défaut, nous analysons les causes possibles de la panne: pompe à huile haute pression et pompe de dosage de carburant (N290), endommagement de la pompe basse pression, blocage ou endommagement du filtre à carburant, endommagement de la buse, la rupture de ligne, la soupape de régulation de la pression du carburant (N276) circuit endommagé ou cassé, les dommages de la carte de l'ordinateur du moteur et ainsi de suite.Parce que nous avons peu d'exposition à la version diesel de l'Audi Q7, l'information est relativement faible demander, pour comprendre la cause de la buse lonsor k518isebrûlé beaucoup de raisons, telles que: bouchon de tuyau d'échappement, buse de cylindre Les trous sont bloqués, le coke, le diesel et de mauvaise qualité. Avant de nettoyer l'injecteur de carburant, nous avons soigneusement nettoyé tout le circuit d'huile, nettoyé le coke de la soupape, nettoyer le collecteur d'admission, afin d'éviter ce qui précède peut entraîner des dommages aux facteurs de buse.

Condition: a BMW 328Li sedan, equipped with N20 engine, the car engine power down, dashboard display information prompted iKeycutter CONDOR XC-mini condor transmission system and DSC failure.

Check the analysis: after the car to test, to determine the customer described as the real existence of the phenomenon. Then the car carried out a quick test, found the following fault information:

1. the pressurized air temperature sensor electrical to the cathode short circuit; 2.pressurized air temperature sensor voltage changes too fast; 3.boost pressure regulation as a follow-up reaction closed; 4.booster pressure sensor electrical to the cathode short circuit.

Next,we measure, step, and conclude based on the test plan that is automatically generated by the above fault code:

1. according to the following figure shows the sensor circuit diagram, in the case of idle measurement of the sensor power supply kess v2 v5.017 line 26 pin and ground voltage between the voltage, the voltage value of 4.97V, indicating the normal power supply DME. Then measured at the sensor side of the No. 2 pin, the voltage is 4.97V, indicating that the sensor to the DME between the normal line. 2.the case of idling temperature sensor 12 and the voltage between the voltage, the voltage value of 2.79V, indicating that the temperature sensor to the DME signal is normal, and the line is also normal. 3. the case of idle pressure measurement of pressure sensor 10 pin and ground between the voltage, the voltage value of 4.97V, this measurement shows that the signal voltage is not normal at idle. And then measured in the sensor side of the voltage on the 1st pin, the voltage value is 4.97V, both ends of the voltage can only indicate that the line no problem. 4. in order to verify whether the system into the emergency mode, then in the ignition switch open and idle 2 cases measured the voltage between the 24th and 10th pins, the voltage value is 4.97V. Depending on the component failure characteristics of the boost pressure sensor, when the sensor fails, it is expected that the following will occur: The fault code is recorded in the engine control unit to replace the value of the emergency operation. At this point DME internal will automatically generate a 5V alternative value to run emergency, according to which we can determine the sensor into the emergency mode. Troubleshooting: Through the above measurement, we concluded that the booster pressure sensor is damaged, replace the new sensor, again in the ignition switch open and idle speed in the case of 24 and 10 measured between the voltage, the voltage values ​​are 1.23V, indicating troubleshooting. Fault Summary: Then xhorse iscancar vag in order to further explain the sensor operating characteristics, we collected it in the normal operation of the idle waveform, found in full compliance with the sensor-related characteristics: booster pressure of the effective signal fluctuations according to changes in pressure. Measuring range of about 0.5V ~ 4.5V, corresponding to 20kPa (0.2bar) to 250kPa (2.5bar) of the supercharging pressure.


Xhorse VVDI Prog Renew bmw E series 868 key

I did renew 2 keys! Both worked and now are programmed to cars! Renew BMW series E 868 key - 100% OK z vvdi prog v4.5.7

Only thing you need to disconnect from PCB is battery while writing the renew file.

I think that is only for those who have older version of that adapter. Older version came with 33 ohm resistor and later they decided that it is not needed and newer adapters like mine came with 0 ohm resistor that is just connecting both sides together without resistance.
If you have that 33 ohm resistor then remove it and short-connect it.
If you have 0 ohm resistor, then don't mind that first box in connection diagram. It's not for you.

I did it in circuit.
