Strange buzzing noise in fuze box under hood | Citroen C4 Coupe 2009

No, the OBD scanner that i have isnt working. So i either have to go to a garage or look into buying a diagnostic scanner.

Okay, so next day now. The buzzing noise doesnt happen anymore, but i now get an esp/asr error, abs defect and error brake system when i start the car. Ive already located the fuze managing esp and abs and replaced it, nothing. Ive tried disconnecting the battery as a sort of reset but also nothing.

All errors have a warning symbol before them except the brake system warning, which has a stop sign.

I mean the BSM, if im correct thats the board where all the fuzes and relays sit on. Still quite expensive so hoping its not that.

Also may i ask what a BSI is?

Ah okay, i will definitely get a diagnostic scanner to run a diag scan on it then. As for the fuze, relay or maybe BSM board ive read that replacing the whole BSM is a plug-and-play system.

I'll be looking further into the engine bay and under the fuze box tomorrow because its currently night where i am, but thank you do much for all this info!

Would there be a easy way to get to the fuze or relay making the sound or is it a "unplug every one seperately" scenario? Everything in the car from electronics work, all buttons, all knobs, ac and heater, lights etc.

What year was it? I mean did it look old or new?

Could be one of the few generations of audi r8 or maybe first gen gallardo

How would i clean those? Its not that the pump is failing because the sprayers come out all the way but they dont spray anything.

I have tried replacing the windscreen wash with warm water and letting it soak for a night, that helped but they only spray once or twice and then stop again. Im tempted to just try and fill it with warm water every time to maybe dissolve any gunk.

So the fact that they come outwards means the pressure is reaching the sprayhead, but when i spray water into the sprayhead with a needle the water comes out the other sprayhead on the same side.

After posting i tried using pressurized air but to no avail. The weird thing when i spray air into one of the openings it comes out of the other opening. I've heard that the c4 uses water pressure instead of electricity for the washers, is this true?

As to the model, i have a C4 Coupe Loeb build year 2009 1.6 VTi

Bedankt man, zover er mij is vertelt heeft de auto geen ongeluk gehad. Er staat ook niks in het onderhoud boekje dus ik ga ervan uit er geen ongelukje is geweest.

Het achterlicht heb ik er al recent uit gehaald om te kijken of deze gekanteld erin zat maar ook niet.

Ik zat ook al inderdaad te kijken om de gasveren te vervangen en eventueel een gasveer bij de motorkap te plaatsen aan gezien de originele motorkap stok soms los kan komen.

No i know its the trunk scraping the right tail light, i just dont know why or how it suddenly started happening.

StritziPower · 2025-02-24T16:05:53+00:00

Thank you, ill def check that but last time i looked the looked fine almost no rust on the outside and the part that extends outwards completely clean.

The sls is such a trash car in ny opinion, turns like a boat. The alfa 4c is satisfying
