Hey I bought this car from previous owner and few weeks back I started to hear some electrical buzzing while I use full throttle and it was like from fuses under steering column. I can’t find any sources for relays only for fuses and I found this weird relay plus 2 fuses and I don’t think it should be there anyone know what it is?

It's not a factory fit so trace the wiring and find where it goes, something aftermarket has been slung in there! Let us know what you find 
its not factory fitted, i ran my dash cam wiring in a very similar way but you wouldnt use a relay for a dash cam, follow the wire that goes up the A-pillar and see what it leads to, previous owner mustve installed some accessory (could be lighting or radar detector or a whole number of things)
That's like someone has done a retro fit push button start ....I have fitted one for someone before on a Ford and looked like that sort of relay
Unless its controlling the starter directly, then I doubt it as these cars start via can, immo signal, 25a relay & on an 8V, I just dont see it personally.
I don’t think it’s that coz I was looking at exterior equipment in my Audi app and there is trailer hitch. I don’t think it’s aftermarket
i don’t think so. Coz I have kesy door handles etc.
I’m a bit scared to do that. Hope I’m not gonna break something
And what about the electrical sound? Did u hear about something like that?
anyway thanks for all answers

With respect, we're ******* in the wind here, answer is simple, follow the cables as advised, pointless us pretending to be mystics here.
Its switching a load that is high, so time to get hands dirty.

i mean if you just want to get rid of the buzzing noise you could just unplug it and leave the wiring there, although i am curious and im sure the others are too, about what it is connected to
I'm making a guess that you mean keyless door entry. If so how would this limit you from having tow bar electrics?
