Scenic II 2.0: Blown Fuse Plate, Melted Resistor, White Relay - Gas Firing & Fuel Injector Issues

Question

Hello all! I had a problem with firing on gas, it did not feed fuel to the injectors. I dismantled the fuse box from under the hood and I can see that some elements are soldered, some resistor is melted and a white relay is soldered on the bottom. Does anyone know what it is all responsible for,...

This is how the problems are gone, I exchanged any configurations for a stimulant, I chose the numbers by numbers and everything works fine.

For the convenience of use, I would recommend buying a new one

these are not some enormously expensive things. Stimulants go for PLN 200-300, but as it has been in another car for 10 years, you can buy it in a slightly better condition (than the one you currently have). After so many years, the pins fall off by themselves, only the problem is to bring it back into action and it is not known for how long it will last.

Hello. Your mod is in terrible condition. Of course, the smell of no fuel or lights (where the wires are soldered) will not work properly on such a module. From what you can see, it is better to throw it in the trash and buy another one. I mentioned because there were problems with firing it with lights ..... etc. after the exchange as he took away with his hand ..... Good luck.

and what did you exchange for, old new? Some configurations later because I understand the problems are gone ....?

THANKS CHOP !!!

IgorEs2 · Answer

welcome back!
Coming back to the topic, I bought, installed, the problem with firing, etc. disappeared, but the stench of burning, burnt cable still remains, I do not know if plastic or rubber, some electrics in general, it only occurs when you put out the car, the question is why ...?

sulof1601 · Answer

And this is not a coincidence that the smell of burnt oil may have a slight leak somewhere on the manifold or muffler and it evaporates. While driving, the rush of air blows so you do not feel and when you stop it, the smell gets inside? I think it is more rational than that the installation in car because she would be gone by now.

IgorEs2 · Answer

Well, I don't know, the evident smell of burnt plastic, rubber, oil is not decreasing, everything is ok, so I rather reject this option, I thought about it beforehand. On the other hand, the stench appears only after the car is turned off and in the vicinity of the driver, the left wheel arch, somewhere under the steering wheel on these sides .... after the car is turned off, the voltage gets something else, maybe an immobilizer, but as you wrote, it only stinks for a while, the electrics should already burn during this time ... something behind the wheel, I don't know, I'm looking for the reason and I can't find it, and the car is running and everything is ok ...

sulof1601 · Answer

If the car behaves correctly and nothing discharges the battery, do not look for fault in the electrical system. If the cable was to melt, the insulation would not be there after a few seconds
check carefully with this oil, because the fact that it is not depleting, it does not mean anything, because one drop on the muffler is enough and an hour will stink, another thing is maybe brake pads, i.e. the caliper holds. you may notice something.

IgorEs2 · Answer

ok, I will check everything right away, but the problem is that it is clearly a smell, the smell of burnt plastic, it does not clutch, not blocks, not oil, he works in the workshop himself and I know what the smells can be, evidently something electric, tpu fan from sensor, cube burned, some short circuit somewhere, I don't know, some resistor, or something at the air conditioning, supply, maybe a resistor ...

sulof1601 · Answer

And you have no problems with the meter?

IgorEs2 · Answer

well, not, once the rest was already replaced, as I mentioned, everything works ...
