Hello, in my car I bought for 4 months, when I took my foot off the gas in 1-2 gears, it was shaking twice, a mechanic said the ears should be changed and the upper-upper-gearbox has changed the master said okay, I did not notice it exactly 1 week later it turned out to be worse. the cost I made was burned, I did not pay attention to the top, I had the others installed elsewhere. What should I say? One of the pumpers recommended 4 injectors, I removed the pump, clean it, it did not work again, then a master crank sensor said that they changed it again, but this time it was scrupulous, let's see why it did not, he connected the pc, we set off on the road, the vehicle cuts power while driving around 70 in vitez At that time the fault P0704 was reported. How many times we tried it always gives this fault. I bought a sub-industry Clutch Contactor, they put it on, it did not work, then they said it must be original, they bought the original, they installed it again. As far as I understand, there is no one who can do it in my city, I want help from an auto electronics friend via the forum, whatever the cost is on my head. For this malfunction, a private Pejo service said "I need an update from the authorized service", I went to the authorized service said it may not pass with an update and the brain may burn or something unstable. I got to work, I understand more or less because I am a telephone repairman, as far as I understand there is a problem with the plumbing-brain, the 2-pin cable is coming to the clutch contactor, white and purple, I found the place that goes to the brain of the two, but the purple one also goes to the brake switch, joins a brown wire. The fuse box on the battery is constantly receiving water, I think there is a cable going to the brake connector, I could not solve the connection. I do not know how to watch it. I think I can do it if I can get help remotely. Thank you in advance for your friends to help you.
