Okay, thanks for the info. I guess I can use it like that for now then, and replace it as I can

Thanks, I will do that! But to be honesty what is this part responsible for? Disconnecting the relay 103 the lighting stopped (I guess it disconnected this whole part), but the car still starts nicely even if it is cold.

it might be the case that the glow plug stayed on. I also realized that the heating is way less strong then before. So could be that you are mentioning. The engine temprature gauge works, but often falls below 90 (70-80). I attach how the glow plug was missfunctionating after changing the connector: I seems to me the the rubber holding of that unit is also broken. WhatsApp Video 2025-01-26 at 20.53.07 (1).mp4

Update: I have changed the burned out connector and the ignition switch next to it. After that the electrcity came back, but my glow plug was doing small lightbolts to the engine. I have removed the relay 103 so now no lighting is happining in the enigne (but i have no glow plug) Car still starts, and I have all features available

Update, I removed the plastic part from the wheel, and there is a connector unit which has a burned out cable. This cable goes to relay 103. Doesn anyone know why this cabel burned out? if I should replace the whole key whole unit and the cable, or something else?

I tried one more thing, I have disconnected relay 103 and with a normal wire I connected the 2 legs between the switch. I expected the same behaviour so it is not the relay itself that causing the problem.

I forget to add, what I also tried I have disconnected the related fuses from the fuse box (2, 12, 16, 18-27, 36 37, 40, 41), I have attached back all relays. But the 4th fuse next to the battery burned out again. My idea was that perhaps one of the things that dont work (i.e. windscreenwiper) does it, so I disconnected them by removing their specific fuses. But it didnt help

Hi everyone, I have an octavia 1fl 1.9tdi (660.000km). I recently have a bit of problem and would be really keen to avoid car service as I am in a foreign country. The 4th 50A fuse next to the battery is burning out as long as I have relay 103 attached. Because of that I dont have front light, turning light, horn, windscreenwiper, and air ventillator. I do have rear and break lights, parking front light, innerlight, and radio. The car starts like charm also. If I detach relay 103 the fuse is not burning out, but I still dont have electricity inside (frontlight,horn, windscreenwiper, airventillator). The fuse is burning out once I start the car, for just giving it electricity it does not burn out, but still I have no electricity available. I have measured relay 103 (trigerring the relay from the battery) and seemed to be working fine. I checked and measured all the other fuses in the fuse box and relays (the ones with circuit diagram) and didnt find any fault. I also tried to attach/detach the relays one by one and see which one burns out the fuse, but only relay 103 does that. At this point I have really no idea what could I do. Do you guys have any tip what could I check? Do you guys know what is relay 103 responsible for? Thanks!

Hello, I am happy joining to the community. I have a skoda octavia 1.9tdi from 2002. My father was the first owner of the car, and now I am using it. We are at 660.000 km. Will it make a million?
